There are some important things to know
about computer and video display terminal use in regards to your eyes and
eyestrain. Staring at your computer screen, smart phone, video game or other
digital devices for long periods won’t cause permanent eye damage, but your
eyes may feel dry and tired.
Although there are no long-term studies at this time, we do not believe there
is any reason to be concerned that 3-D movies, TV or video games will damage
the eyes or visual system.
Normally, you blink about 18 times a
minute, but you only blink half that often while using computers and other
digital screen devices, whether for work or play. Reading, writing or other
intensive “near work” can also cause eyestrain of a similar nature.
It is helpful in avoiding computer
related eyestrain if you first position yourself about24” from the screen you
are viewing and with your eye gaze is slightly downward. It also helps to
reduce glare from the screen by lighting the area properly and if possible use
a screen filter if needed. It may seem silly but post a note that says “Blink!”
on the computer as a reminder. Then, use the “20-20-20” rule. Every 20 minutes,
shift your eyes to look at an object at least 20 feet away, for at least 20
seconds. It is also helpful to use artificial tears to refresh your eyes when
they feel dry. Make sure that you take regular breaks from computer work, and
be sure to get enough sleep at night. Now, if you wear contact lenses
for the computer screen it’s important that you use and care for them properly
in order to avoid eye irritation, swelling, infection and vision problems.
Also, give your eyes a break and wear your glasses instead of your contacts
sometime. Consider a special prescription and lens coating for computer
use to help manage eyestrain and fatigue.
