One of the main reasons of vision problems are refractive errors. Farsightedness (hyperopia), nearsightedness (myopia), astigmatism, presbyopia are all examples of vision impairment caused by refractive errors.
This is a common condition which generally occurs due to excessive drying out of the eye surface due to constant use with infrequent blinking. Although it’s a minor issue, regularly occurring symptoms of eyestrain could be an indication of something more serious.
This condition results due to insufficient production of tears by damaged tear glands or (excessive near work with infrequent blinking). Tear production is necessary to moisten our eyeballs and to wash away any foreign particles in it. Without this healthy coating of tears, the eyeball becomes dry, leading to blurred vision, itching or burning sensation, and a sensitivity to light.
Macular Degeneration is an incurable eye disease, which is also one of the leading causes of vision loss. This occurs because of the deterioration that is mostly age-related, but can also be accelerated by factors like the sun that causes damage to our eyes because of UV rays.
Cataract formation is caused by clouding on the surface of the lens that hampers with clear vision. It generally develops slowly, and is most commonly seen in elderly patients.
This disease directly damages the optic nerve in the eye, because of excess pressure due to fluid build up in the front part of the eye. Glaucoma is another leading cause of blindness in people, especially elderly patients.
Patients of diabetes who have had the condition consistently for longer time are at risk of developing Diabetic Retinopathy or Diabetic Eye Disease, where the retina gets damaged because of high blood sugar, causing complete or partial vision loss.
