Here we need to think a little more about the change in the pattern of use of our eyes. Our focus of use has shifted to a large extent from paper, print reading to screen reading. Screen reading can be on mobile or tablet or laptop, desktops. All these screens have an enlightened background. 

So, our eyes get exposed to direct light for long hours. Remember, in the past, we were never exposed to direct screen light so much. For studies, office work, writing pen, and paper were the medium. There was no direct light. The room was sufficiently enlightened, and we use to study or work, so it was always an indirect light. 

Dry Eyes

Continuous exposure to light increases the dryness of the eyes. If we talk about the working hours, they were limited before. There was a concept of “office hours” which used to be 8 hours a day. Then the rest of the day used to spend with family or friends, which means there was no continuous exposure to light. 

There were many other activities where our eyes were working in a relaxed manner, not much focused on any screen. Nowadays especially in the IT sector “Office hours” concept has almost abolished. People are always logged in, or available on call.

Environment also adds a lot to our eye-health. Dust, pollution in the air, seasonal pollens, continuous use of air conditioning, dry air, seasonal dryness in the air (like winter) contributes to eye drying.

What we eat reflects on our health and so is true with our eyes too. For food, it is important what you eat and when do you eat? Both have equally important effects.
