What is 20-20-20 Rule of Eye Care
The eye is a vital body organ that we shall take
care of. Unfortunately, several habits seem to
impact the eyes health, such as computer usage,
TV screen, or mobile phones for a long time,
which cause eyestrain that leads to sore, tired
and itchy eyes. Add to headaches, soreness in the
back, shoulders, or neck. Jeffrey Anshel, an
American optometrist who developed the 20-20-20
rule for eye care (1), implies that every 20
minutes of screen time, we need to take a
20-second break to look at something 20 yards
away.

seconds is sufficient time for the eye to relax.
Someone can spend this break time far from any
digital screen by walking around, grabbing a
hydrating drink, and ideally looking at something
that is 20 feet away. It might be challenging
for someone to precisely measure the distance of
20 yards therefore, it can be estimated by
looking from the window at a tree down the street
or at other buildings across the street.
Alternatively, one can close their eyes for some
relaxation time. Looking at digital devices might
not directly damage eyesight. However, when we
look at screens or electronic devices, we tend
to look and blink less frequently, which causes
eye dryness, soreness, and redness. Therefore,
we need to remember to blink frequently to
prevent a dry eye.
