What are some of the must things that a person should do to take care of his eyes?
Surprising to many- not much!

Our eyes are designed to self-service itself.

Just the act of blinking has several functions:

Blinking lubricates the eye with tears

The tear film forms a layer of optically smooth surface for you to have clear vision.
Tears contain antibacterial substances and enzymes which protects the eyeballs against
infections and inflammation.

Blinking cleans the eye of dust particles and dirt just like a wiper of your car.

​​If your body is healthy, your eyes will be too.

Everything that is required for a healthy lifestyle also applies to the eyes.

A balanced antioxidant rich diet
Regular exercise
7-8hrs of uninterrupted sleep
Positive attitude.
Eyes are the windows to the body

One of the very less known facts about the eyes is that many of the effects of diseases
in the body- Diabetes, Hypertension, auto-immune diseases, brain disorders, etc.- can
be observed by looking at the eye with a microscope. Many diseases can be diagnosed
by examining the eyes with certain instruments. This video by national geographic is a
brilliant demonstration of what I'm saying.

However modern lifestyles can give rise to several occupational problems.

Computer vision syndrome.

With the advent of modern technology and our work involving spending long durations
staring at screens, it does impact the eye. Staring at bright screens causes you to blink
less causing your corneas to dry up. Eyes drying up causes corneal epithelial erosions
which causes irritation. When you sleep the corneal epithelium heals and hence you feel
better after that rest.

The ways to counter this problem would be

To use over the counter tear substitutes which are preservative free. (Genteal /Refresh
Plus) for symptomatic relief.

But mainly one has to make a lifestyle modification to improve one's dry eye condition.

Do not work with screens for more than one hour at a stretch.

Take a break every 45-60 mins for 5 mins and close your eyes for that period and then
focus on some distant object and then resume working on your computer.

Also whenever you stare at screens blink more often (and you have to do that consciously).

Self Diagnosis over Google

This is also a hazard of modern living. I have at least two newly minted software
engineers coming to my office every week thinking they are smarter than all doctors
because they know how to google stuff on the internet. I'm bemused that they treat
internet like some God having all the answers to life's problems.

Sorry to burst the bubble- not everything on the internet is true just because it is there.
The reliability of the source is important. There will be several websites claiming if you
instill 'cow urine' into your eye that will cure you of 'eye disease'. That doesn't make it
true!

Protection against external trauma

It is a very important aspect and I would like to stress that protection to the eye and
head is very important.

Many eye and face injuries can be prevented by just using helmets while riding bicycles,
motorbikes and other activities which involve a high risk of falling down.

Using eye protection while playing contact sports or any sport where injury to the eye is
a possibility is important. For reference read about how the cricketing careers of Saba
Karim and Mark Boucher ended.

Protective eye gear while working in hazardous occupations like welding, polishing and
grinding cannot be overstated. It prevents unnecessary hospital visits.
