13 Eye Health Related FAQs

Have doubts about eye health? Check out the FAQs below:

1) How do cataracts develop and what are the treatment options?

There are two risk factors for the development of cataracts; age and exposure to ultraviolet rays.

Age-related cataracts occur when proteins in the eyes form clumps and restrict the amount of light that enters the retina. Prolonged exposure to ultraviolet rays is another cause of cataracts. Other causes of cataracts include eye diseases and eye injuries.

Cataracts can be treated with an eye surgery in which the surgeon replaces the cloudy lens with a clear, artificial lens. But the surgery should be done from the best eye hospital in West Bengal.

2) How is cataract diagnosed?

Cataract can be diagnosed through a comprehensive eye exam, including dilated eye exam and visual acuity test.

In a dilated eye exam, the doctor dilates the pupils using eye drops. By doing this, the doctor can determine cataracts’ opacity and impact on vision. The doctor is able to determine the extent of vision impairment through the visual acuity test.

3) Can I get a cataract surgery done during summers?

Yes. You can undergo a cataract surgery during summers. In fact, you can undergo a cataract surgery during any time of the year. Cataract surgery not being feasible during summers is just a myth.

4) What is diabetic retinopathy and what are its symptoms?

Diabetic retinopathy is a complication of diabetes; the eye condition is one of the leading causes of blindness. It occurs when high blood sugar levels damage the tiny blood vessels in the retina.

The early symptoms of diabetic retinopathy go almost undetected, but can gradually worsen over time, leading to vision loss. Some of the common symptoms of diabetic retinopathy include eye pain, double vision, eye floaters and spots, and blurred vision.

5) Who are at the risk of diabetic retinopathy?

People suffering from diabetes, both Type 1 and Type 2, stand at the risk of diabetic retinopathy. Pregnant women with diabetes are at the equal risk. Disha Eye Care Hospital is the best among the top ten hospitals for retina treatment in Kolkata.

6) Can diabetic retinopathy be prevented? If yes, how?

There are several steps to lowering the risk of diabetic retinopathy. Managing diabetes is the first step to minimising the risk of onset of the eye condition. Other steps involve regularly checking blood sugar levels, testing urine for ketone levels, and undergoing an annual comprehensive eye exam.

7) Can eye injuries affect vision?

Yes, but it totally depends upon the severity of the eye injuries. Minor injuries can cause eye pain and temporary blurred vision while major injuries can have serious implications such as eye infection and vision impairment.

8) How to protect the eyes from diseases?

There are several ways how you can lower the risk of development of eye diseases. First off, maintain a healthy diet by choosing fresh vegetables, fruits, eggs, meat, and fish over unhealthy food items such as deep-fried snacks and frozen meat items.

Exercise regularly, drink plenty of water, and get your eyes checked every year. These steps help you maintain an overall good health and keep the risks of eye diseases at bay.

9) What is glaucoma and what are its symptoms?

Glaucoma is a group of diseases that can cause vision loss by damaging the eyes’ optic nerve. The eye disease is linked to the build-up of pressure (intraocular pressure) inside the eyes

Some of the common symptoms of glaucoma include eye pain, narrowed vision, nausea, vomiting, eye redness, vision loss, and seeing halos around the light.

10) What are the treatment options for glaucoma?

Your doctor may plan the treatment depending upon the severity of the condition. Eye drops for Glaucoma can either increase fluid flow or reduce its formation in the eyes.

Laser surgery is another treatment option for glaucoma. This procedure can help increase fluid flow in the eye. A surgery known as Trabeculoplasty involves opening a new channel to drain the fluid and lower eye pressure.

11) Why is it not safe to wear contact lenses past expiry/recommended date?

Contact lenses (as the name suggest) get into direct contact with the eyes when worn. Therefore, it’s crucial that you follow safety precautions to avoid serious implications. Wearing contact lenses past their expiry date can increase the risk of eye infections, which, in turn, can worsen and cause vision impairment.

The same applies to the cleaning solution. Make sure that you replace it after reaching the expiry date.

12) Will reading in dim light damage my eyes?

Reading is a precision activity, and when you do it under dim lighting, you increase strain to your eyes. As a result, you can suffer from symptoms such as eye redness, itchiness, pain, and dryness. The best practice is to read under bright lighting.

13) How to avoid eye injuries?

Eye injuries cannot be completely avoided. However, you can take steps to drastically lower the risks. For example, wear a protective eyewear when working at the workshop or travelling outdoors.

Glaucoma is one of the most common eye diseases as it affects millions of people worldwide. The eye disease is common in older adults. It involves build-up of pressure in the eyes and impairment of vision.

Glaucoma can affect the quality of life as patients face discomfort and difficulty in doing regular activities with deteriorating vision.

Coping with changing vision:-

As Glaucoma starts to worsen, it affects the vision. Low vision is one of the most common symptoms of the eye disease. Low vision can hamper the quality of life as it can cause difficulty in doing everyday work such as reading, working on a computer, driving, cooking, etc. In most cases, patients aren’t able to cope with low vision caused by Glaucoma even by wearing prescription glasses or contact lenses.

The best way to cope with low vision is to use visual aids or visit the best eye care hospitals in Kolkata for glaucoma treatment. There are a number of visual aids available including colours lenses, magnifiers, and computer text enlargers. Talk with your doctor to choose the visual aid that best suits you.

Getting organized:-

Getting organised is the key to dealing with vision changes caused by Glaucoma. It’s important to designate a specific place for every item. For instance, keep the keys, medicines, and your purse in a specific place where you have no difficulty reaching for them. It’s highly important that other members of the family respect and maintain the organisation system.

Marking and labeling items:-

Glaucoma patients with low vision face a great deal of difficulty working with specific items such as washing machine, microwave oven, etc. If you are on the same track, use a dimensional fabric paint to mark everyday items to feel the correct positions with your fingers.

Label your medicines with a highlighter to properly store them and have no difficulty finding them.

Improving lighting:-

One of the most important changes to make for dealing with low vision caused by glaucoma is to improve lighting in the home. Make sure that your home is properly illuminated. Use additional lights while working on a specific task. Also, improve lighting in rooms such as kitchen, hallway, and bathroom where there are risks hazards. When your home is properly illuminated, dealing with low vision becomes much easier.

Increasing contrast:-

Increasing contrast in every item helps you to better cope with low vision. For instance, use a white cup for your tea and coffee, use white chop boards for dark coloured vegetables. Increasing contrast is the key to effectively dealing with vision changes.

Listening to audiobooks:-

Googling all of your concerns can be a difficult task when you have low vision caused by glaucoma. This is where Audiobooks come as a great help as you don’t have to rely on your vision while taking in information.

8 Questions on Cataract Surgery

8 Questions on Cataract Surgery

Cataracts are one of the leading causes of vision loss all over the world. Fortunately with, advances in medical science, the eye disease can be treated through a specialised surgery known as cataract surgery.

Although cataract surgery is the sole treatment option for the eye disease, there are confusions and misconceptions about it. Here, we seek to clarify them by these 8 commonly asked questions:

1)  How is cataract surgery performed?

Before the surgery day, the doctor will give you medicines to relax you and numb your eyes. The doctor uses a local anaesthetic which makes the surgery virtually painless. The first part of the surgery involves removing the clouded lens. To do this, the surgeon, with the help of precision tools, makes a small incision in the eye to remove the natural lens. The surgeon will use the same incision to place the artificial (intraocular) lens. To get the best cataract surgery in Kolkata, contact Disha – Best Eye Hospital in West Bengal.

2) What is the success rate of cataract surgery?

Cataract surgeries have a high success rate. In fact, cataract surgeries are one of the most successful surgeries performed the world over. It’s because of the high success rate of cataract surgery that it is chosen as the sole treatment option for cataracts.

3) How do I determine whether cataract surgery will benefit me?

There are several ways how you can benefit from a cataract surgery. First, the eye surgery is a quick procedure and can be completed within 2 hours. Plus, you don’t have to get admitted to the hospital as it’s required with other surgeries.

By undergoing a cataract surgery, not only is your eye disease treated but you also have your vision corrected. Lastly, the recovery period for a cataract surgery is quite short. It may take you as less as a week to fully recover.

4) Are there any side effects of a cataract surgery? 

After the surgery, you may experience itchiness, slight discomfort, and redness. But these effects only last for a couple of hours and eventually subside. Your eye doctor may suggest you tips to fully take care of the operated eye(s) post-surgery.

5) What is phaco?

Phaco, or Phacolemulsification is a technique used during a cataract surgery. In this technique, the eye surgeon makes a small incision to insert a tiny ultrasonic probe. The doctor uses the probe to break cataracts into tiny pieces. The next step involves removing the tiny pieces using a suction. After the cataracts are completely removed, the doctor inserts the intraocular lens.

6) What is an intraocular lens?

Intraocular lens is a small convex-shaped lens and is harmless to the eyes. Apart from being an alternative to the natural, clouded lens, intraocular lens also helps correct vision. Once the intraocular lens is placed during the cataract surgery, it does not move and remains in the eye permanently. There are several types of intraocular lens and your eye doctor can choose the best lens for you.

7) Is it true that I have to wait for my cataract to become ripe in order to undergo a cataract surgery?

Previous cataract removal methods involved heavy sedation and making large incisions so that the entire affected lens could be wholly removed from the capsular bag. As such, ripe cataracts would make the removal process easier.

But with technological advancements, modern-day cataract surgeries require a small incision and minimal sedation as the lens is suctioned out. In other words, you don’t have to wait for your cataracts to become ripe for undergoing a cataract surgery.

8) Where can I opt for a safe and quality cataract surgery in West Bengal?

If you or someone in your family is planning to undergo a cataract surgery, then our advice would be to get a precise diagnosis at Disha Eye Hospital, one of the best eye hospitals in West Bengal.

Teens and Contact Lens: Useful Guide for Parents from Disha Eye Hospital

eye care professionals

Are your teenagers tired of wearing heavy spectacles? Are they asking for switching to contact lenses? It’s usual for the teenagers to feel that clunky and thick glasses cramp their style.

By the time the children turn 13, they become aware of the way they look. And as parents, we understand that you are concerned about your teen’s eyes, and so we are too! That’s why we have tried to address your concerns in this guide.

Let’s dive in.

Wearing Contact Lenses: What’s the ideal Age?

The issue is not the age but it’s whether they are mature enough to handle the responsibility that comes with wearing lenses. Usually, eye care professionals never recommend contact lenses to kids until they are at least 13 years old.

It’s because younger kids aren’t mature enough to handle contact lenses properly. It is often suggested that if you are considering contact lenses for your teen, it’s important that you first evaluate how they handle their responsibilities, especially personal hygiene.

You need to be vigilant about whether your teen is handling the contact lenses properly or not. Kids and teens often tend to moisten the lenses using saliva or buy coloured lenses from beauty stores just for the sake of fashion.

These are extremely dangerous behaviour and can put their eye safety at stake. If only the teen is mature enough to care for the lens properly and use it as per the recommendation of the eye care specialist, you may consider allowing them to use contacts.

Determining the Best Contact lenses for your teenager

There are a number of factors that should be considered to determine which contact lenses suit your teen. But before that, let’s take a look at the type of contact lenses that are available.

Types of Contact Lenses

There are several varieties of lenses to choose from:

  • Soft contact lenses: Most of the people opt for soft lenses as these are comfortable to wear. People who have sensitive eyes can easily wear soft lenses. Standard soft lenses can correct vision issues such as farsightedness and nearsightedness. Specially designed soft contact lenses are known as Toric Contact Lenses and can also correct Astigmatism.
  • Gas permeable (GP) contact lenses. These lenses are made of a rigid plastic that’s oxygen-permeable. These lenses do not allow oxygen to reach your lenses. These lenses provide sharp vision than soft lenses but these take longer to adjust. These lenses can correct farsightedness, nearsightedness, and astigmatism.
  • Hybrid contact lenses. The central part of these lenses is made of a GP material. This gives you a crisp vision. The central part is surrounded by a soft lens that allows you great comfort. These lenses can correct astigmatism, farsightedness, and nearsightedness.
  • Daily wear Contact lenses. These lenses come in categories such as extended wear, planned replacement, disposable and daily wear contacts.
  • Contact lenses with sun protection. There are many lenses that safeguard your eyes from UV rays. However, if you are using these lenses, always use UV protected sunglasses while stepping out in the sun.
  • Tinted Contact lenses. There are many contact lenses that have a light “handling tint.” These are colour enhancing lenses and can give change the appearance and colour of your eye lenses.Teens who do not have vision issues can also use coloured lenses. Particularly, if they are into sports, there are lenses available with a special tint that can increase contrast. So, your teen can see the baseball or tennis ball clearly. Before wearing any lens, always consult an eye care expert.
  • Customised contacts. These contact lenses are used to mask scars or corneal irregularities cause by eye disease or injury.

How to determine the type of contacts your teen needs?

Consider these factors while selecting the best contact lenses:

  • Choose extended wear contacts if your teen has the habit of wearing lenses for long hours and forgets to take them out before sleeping. However, not all eyes can tolerate extended wear lenses.
  • Bifocal or multifocal contact lenses can be used if your teen has presbyopia. However, if these are of not much help, consult the doctor and see if your teen has monovision or not. In that case, the doctor may suggest monofocal lenses for one eye with distance vision and another lens for near vision.
  • If your teen wants the sharpest possible vision but cannot wear gas permeable lenses comfortably, then go for hybrid contact lenses.

Consult an Optometrist or Ophthalmologist before selecting any contact lenses for your teen’s eyes.

Talk to the doctor. See what he/she suggest. If they suggest your teen to wear a disposable lens then always go for daily disposable soft lenses instead of the cheaper disposable lenses that are usually worn for two weeks before disposing off.

Taking care of these lenses is simple. Your kid need not disinfect and clean them daily. Moreover, your kid will learn how to wear them in and take them off faster if they have to change it every day.

What about Decorative Contact Lenses? Are they good for your Teen?

Coloured and cosmetic contacts have fast become a teenage fad. And it’s usual for you to be concerned about your kid’s vision. Your teenager child may want lens colours like his/her favourite actress or actor.

But it has to be kept in mind that using coloured lenses without consulting an eye specialist can be risky. Low-quality lenses may cause injury, serious eye infection, and even vision loss.

Coloured or decorative contact lenses can change the way the eyes look. For instance, if the eye lenses are black, using coloured lenses you may turn them blue, brown, or green. However, these lenses do not correct vision. Never buy coloured contact lenses from flea markets or beauty stores and without prescription. It comes with numerous risk factors.

Contact lenses not only help the teenager see better but also makes them feel better. Glasses often block the peripheral vision or the side vision. This can be problematic for them.

With contact lenses, peripheral vision won’t be an issue. Also, glasses go out of style with changing fashion norms (in case your teenager is fashion conscious). Some may not like wearing glasses at all, especially when their vision issue is severe and they are using super-thick glasses.
Often they might get ridiculed for it. Contact lenses are an effective solution for it. However, in any case, contact lenses should not be considered as a fashion accessory.

Decorative Lenses: Know the Risks

Wearing decorative contact lenses is risky. Even if your kid is using contact lenses for vision correction, not using them properly can cause serious damage to the eyes.

The risk includes:

  • Corneal Abrasion (A scratch or cut on the cornea, the topmost layer of your eye)
  • Itchiness and redness of eyes
  • Excessive tearing
  • Hazy vision
  • Infection
  • Blindness

Eye infection is pretty common when your teen wears any type of lens without any prescription or without consulting the doctor. Rush to the eye specialist immediately of they complain of:

  • Redness
  • Pain in the eye(s) that won’t go away for long
  • Hazy or blurred vision

These are symptoms of eye infection and if not treated properly, it might even cause complications and even blindness.

Ensure that your teenage kid is following the doctor’s instruction regarding cleaning, disinfecting, and wearing the lenses.

Taking Care of Contact Lenses: the Do’s and Don’ts

If your teenager is considering wearing contact lenses then ensure that they should be following these tips:


  • Ensure that they always wash and rinse their hands properly before handling the lenses or before touching the eyes. For washing the hands, they must use mild non-cosmetic soap. It important to dry the hands with tissues or a lint-free cloth before handling the lenses.
  • After removing the lenses, ensure that they clean their lenses as instructed by the eye care practitioner. Never use anything except the recommended solution to do so.
  • At least once in a week, clean the lens storage case with warm water. Make sure to rinse them properly and wipe dry with clean tissue.
  • When handling lenses always make sure to work over a clean flat surface. Never handle the lens over a sink and even if you do, plug in the sink first.
  • If you drop your lenses, clean and rinse them thoroughly (using the solution) before wearing them.
  • Consult an eye care expert if your teen experiences pain, discomfort, redness, excessive tearing for no apparent reason. These are symptoms of an eye infection.
  • Always replace the lens solution one month after opening. Throw it away even if you haven’t finished the container.
  • Let you teen carry the storage case and solution with them wherever they go.
  • Always keep their eyeglasses up-to-date so that they may use them in case the lens is broken or if they have lost them or have been advised to not use them for a certain period of time.
  • Do not let any chemical get into their eyes. Ask your teenage child to close their eyelids while using hairsprays and any other cosmetic sprays. These sprays may form a residual layer on the lens.
  • Ask them to always wear goggles when swimming while wearing contact lenses. Ask them to wear protective glasses or sunglasses in situations when there are chances of dust, sand particles and grit entering the eyes. For instance, wearing protective glasses is a must while gardening, riding bikes, sanding etc.
  • In case foreign material has entered their eyes, ask them to clean and replace the lens. If you aren’t sure that the dust particle is removed, avoid rubbing the eye and immediately contact the eye care specialist.


  • Do not wear lenses if you are not feeling well.
  • Never wear lenses if your eyes are unusually red, itchy, and uncomfortable
  • Never put a lens in your mouth or use saliva for cleaning or lubricating them.
  • Do not use tap water for cleaning lenses. Never soak them in water or rinse them.
  • Avoid rubbing your eyes while wearing lenses.
  • Avoid mixing up your lenses. Your teenager might get confused when using a lens for the first time. The best way to avoid this confusion is to always wear the right lens first. Ensure that it sits safely on your eye or in the storage case before trying out the left one.
  • Avoid exposing the lenses or storage case to extreme temperature or heat.
  • Never apply eye makeup inside the waterline. Teenage girls must use eye makeup sparingly if wearing lenses. Even if they are applying then they should do it on the upper lid only.
  • Do not swap contact lenses with anyone and know when to replace a contact lens.
  • Always ask your teenage daughter to use hypoallergenic skin products and products that are specially made for those who wear contact lenses. Also, ask them to always put eye makeup after wearing the lenses and not before them. This saves the lenses from chemical contamination.

If your teenage kids have seasonal allergies, then wearing lenses is not recommended for them. An ophthalmologist or eye care practitioner is the best person to guide you in this regard.
