A weekly blog, well let’s get started.
Quarantine
- from the French for 40, quarante, the number of
days a ship would be left in harbour if it had disease.
During these interesting times, most of us find ourselves at
home, in isolation or even quarantine, our time being spent in front of
screens, working, watching the Covid drama unfold, zooming with friends and
family or binge-watching 11 seasons of Friends.
And yes, our nerves are frayed and our eyes are not far
behind. It is a good time to remember
that positive steps can be taken to help your eyes. Your eyes start to dry when you stare at a
screen, because staring slows your blink rate down, as much as half for
some. The tear film evaporates on the
eye and causes drying to occur, with resulting redness, foreign body sensation,
and even transient blur. You need to
remember to consciously blink, so that your rate is more normal, about every
five seconds. If you still are getting
symptoms, then an artificial tear can be of help. And finally, if dry eyes still persist you
can turn the screen off and do something else for a while.
Then there is exposure to high energy visible light, the
blue-violet variety, that comes off of screens.
This exposure causes fatigue and messes with our sleep patterns. Blue filters are helpful if you can get a
hold of them, or you can change your display settings to reduce blue
light.
Finally, take breaks. Everybody knows it is the year of the
optometrist, 2020, which helps us remember the rule 20/20/20. The WSIB recommends that after spending 20
minutes on screen, take a 20 second break, looking at an object at least 20 feet
away from you. Another great habit you can
adopt.
All this should help your eyes during these trying times.
Keep Safe, until next week,
The Good Doctor
