Cataracts and Glaucoma are two of the most serious eye complications. Both the degenerative eye diseases occur as the natural part of the aging process and cause vision impairment. However, the eye diseases have stark differences in between them.
Let’s uncover the key differences between these two serious eye complications to get a clear picture:
1) Symptoms: While symptoms including eye pain and vision blurriness are common in both eye complications, the other symptoms that are different:
- Double vision in the single eye
- Yellowing of colours
- Clouded vision
- Appearance of cloudy formation on eyes’ lens area
- Lowered vision in dimly lit areas
- Seeing coloured rings around lights
- Sudden disturbances in vision
- Eye redness

The way Cataracts and Glaucoma cause vision loss are completely different from each other, and so are the factors that cause them.
Cataracts: The eye complication occurs when the eye lenses become stiffer, start breaking down, and form clumps as you age. As the eye disease progresses, the clumps become denser and start clouding the lens. This, in turn, obstructs light to completely pass through and reach the retina which results in blurred vision. Cataracts can either develop in one eye or both eyes. In cases where cataracts form in both eyes, the clouding of the lens is not even.
Glaucoma: Glaucoma occurs when the intraocular pressure (IOP) increases above normal levels and damages the optic nerve. The IOP increases when the fluid (aqueous humour) in the front of the eye builds up when it is not drained as properly as it should.
As the IOP increases with time, more damage is done to the optic nerve, which, in turn, leads to gradual vision impairment.
3) Vision loss restoration:-
As discussed above, both the eye diseases cause vision loss. However, vision loss can be restored and reversed only in Cataracts and not in Glaucoma.
Cataract: Cataract surgery, the go-to treatment option for cataracts, involves replacing the clouded lens with an artificial lens. Before the surgery, the doctor takes into account the refractive error of the patient to choose an artificial lens accordingly to correct the vision.
Glaucoma: The goal of treatment options for Glaucoma, including eye drops and surgery, is to reduce and stop vision loss from worsening by lowering IOP. Depending on the severity of your Glaucoma, the eye doctor may start treatment by prescribing eye drops or schedule a surgery.
Both Cataracts and Glaucoma cannot be entirely prevented. However, you can take certain steps to lower the risks. Some of these include:
- A healthy and balanced diet:
Eating healthily is key to maintaining good eye health and lowering the risk of complications. Add green vegetables, colourful fruits, fresh eggs, and lean fish and meat to your diet to make sure you get proper nutrition intake.
- Regular exercise:
Exercising regularly helps improve blood circulation in the eyes. Another key benefit of regular exercise is it helps you maintain healthy body weight. Being overweight and obese increases the risk of diabetes which, in turn, can cause a vision-threatening eye disease known as Diabetic Retinopathy.
