Excel Optometry

We all know that excessive screen
time can have negative effects on things like attention span, mood, obesity,
and circadian rhythm. However, what you may not know is that screen time is
also linked to an actual condition called Computer Vision Syndrome or CVS–and
this condition is accompanied by a myriad of symptoms such as:

• dry eye
• headache
• blurred vision
• neck pain
• shoulder pain

If you suspect that your vision has changed or you are
experiencing these symptoms, consult a licensed optometrist and ask for a
vision test and eye exam. Mild over the counter eye drops which are only for
hydration are safe to use if you are experiencing dry eye. 

Interestingly, dry eye occurs not because of the screen
itself but because the eye does not blink as often when looking at a screen.
Less blinking means less lubrication because blinking is what keeps our eyes
moisturized. In addition to this, the eye being exposed to air for a longer
period causes the existing moisture in the eye to begin to evaporate. This
combination of factors causes our eyes to become drier than usual. 

Another thing you can do while you wait for your eye
appointment is to change the settings of your phone, tablet, or computer. Most
if not all devices give the option of emitting either cool or warm light, and
some have the option to switch to warm light in the late afternoon or evening,
mimicking natural light temperature and thus interfering less with your body’s
natural neuro- and physiological response to light.  However, if possible,
nothing helps quite as much as reducing screen time–although considering the
amount of people who work on a computer all day, this may not be
realistic. Take breaks and close your eyes periodically while working.
Getting on your device outside of working hours–or at least before nine
pm–will also make a large difference, especially if you are having difficulty
sleeping.
