Blinking and rest prerequisites for optimum eye health

Majority of the people ignore eye health and do not take precautions

HEALTH DESK

According to a recent study, lack of awareness about eye-related diseases and its symptoms leads to delay in seeking treatment. While diseases affecting the cornea (front of the eye) are easily diagnosed, those affecting the retina (back of the eye) are rarely recognized. Despite being one of the most vital organs of the body, eye health is ignored by many.

Retinal diseases such as Age-Related Macular Degeneration (AMD) and Diabetic Macular Edema (DME) lead to chronic poor vision. Diabetic macular edema (DME) is the most common causes of moderate vision loss in patients with Diabetic retinopathy (DR). AMD constitutes for 8.7% of blindness in the world.

Speaking about this, Padma Shri Awardee, Dr KK Aggarwal, President, HCFI, said, “Apart from the deterioration of eye health due to certain conditions, expanding areas of arid land, air pollution and greater exposure to ultraviolet (UV) radiation all present potential health hazards to the eyes. The cornea, eyelid, the sclera and even the lens—are all exposed directly to the environment. Rising temperatures and shifting atmospheric circulation patterns force dry air into regions. Drier air means that more people are likely to suffer from dry eye, a condition in which tears aren’t produced properly or evaporate too quickly. There is no evidence that drier conditions cause dry eye, but they can accelerate symptoms in people who are prone to dry eye. Air pollution has long been linked to respiratory disorders; more recently it’s been shown to play a role in eye disease.”

Recurrent infections over a lifetime lead to scarring inside of the eyelids, which in turn causes the eyelashes to turn inward and brush against the cornea, eventually resulting in damage that impairs vision.

Adding further, Dr Aggarwal, who is also the Group Editor-in-Chief of IJCP, said, “Eye exercises may not improve or preserve vision, help eye health, or reduce the need for glasses. Our vision depends factors such as the shape of our eyeball and the health of the eye tissues. Neither of these can be altered greatly by eye exercises.”

Using a computer does not affect eye health. However, staring at a computer screen all day can contribute to eyestrain or tired eyes. People who stare at a computer screen for long periods tend not to blink as often as usual, which can cause the eyes to feel dry and uncomfortable. To help prevent eyestrain, adjust the lighting so it doesn’t create a glare or harsh reflection on the screen, rest your eyes briefly every 20 minutes, and make a conscious effort to blink regularly so that your eyes stay well lubricated.
