Question 1: What’s a refractive error?

Answer: Refractive error is an eye condition when the eye is unable to properly bend and focus light on the retina. When the light bends incorrectly, and is focused in front of the retina, the person has myopia (nearsightedness). When the light is focused behind the retina, the person has hyperopia (farsightedness).  Astigmatism is another refractive error caused by uneven shaped cornea. At Disha Eye Hospitals, refractive surgeries are performed in order to correct refractive errors and reduce a person’s dependency on glasses or contact lenses.

Answer: The lens is the clear structure in the eye that focuses on entering light. As people age, a normally clear lens becomes cloudy. This cloudiness is called cataract. A cataract can block incoming light and affect vision in many ways.

Question 3: What are the symptoms of cataracts?

Answer: Cataracts can cause different symptoms for different people. During the early stages, a mild cataract may not signal any symptoms. But with time, as the cloudiness progresses, less light enters the eye and people start experiencing symptoms such as

    Question 4: What is glaucoma? And who gets glaucoma?

    Answer: Glaucoma occurs when the pressure of the fluid in the eye increases, leading to damage of the optic nerve and loss of vision, and possibly, blindness. Patients with diabetes and advanced retinopathy stand at a higher risk of glaucoma. You can read about more risk factors here

    Question 5: What are the symptoms of glaucoma?

    Answer: At first, there are no symptoms – which is why glaucoma is often called the “silent thief of sight”. As the condition progresses, the patient may notice his/her side vision worsen over the period of time, even if the central vision functions perfectly. In many cases, the loss of peripheral vision goes unnoticed by the patient. If left untreated, the patient may gradually lose their central vision.

    Question 6: What is diabetic retinopathy? What are its symptoms?

    Answer: Diabetic retinopathy is an eye disease that affects patients suffering from uncontrolled diabetes. In this condition, the tiny blood vessels that nourish the retina are damaged. Due to the damage, the blood vessels swell and leak. There are two stages of diabetic retinopathy: – Non-proliferative diabetic retinopathy and proliferative diabetic retinopathy. You can learn about these stages here . There are often no symptoms until the later stage of the disease. If you are a diabetic, then you must go for an annual eye check-up. If you experience blurred vision, floaters, dark spots, impaired colour vision, visit your nearest eye hospital immediately.
