If you use a computer all day like I do (all of us seem to be glued to our computers and smartphones these days), you’ll most likely suffer from eyestrain at some point. Many people suffer from it constantly.

Working in ophthalmology, I’ve had rigorous training under the supervision of an ophthalmologist and specialized in the cornea, cataracts, and retina as well as how systemic disease affects the eye. I am certified by JCAHPO as a Certified Ophthalmic Assistant. The most common complaint that I see daily is eyestrain. While some people have a medical reason for their eyestrain (macular pathology, cataracts, etc.), most of us suffer from the common causes. Symptoms of eyestrain vary from patient to patient, but here are some of the most common:

  • A burning Sensation
  • A “pulling” sensation
  • Irritation and redness
  • Itching
  • The sensation of something in the eye (also known as a foreign body sensation)
  • Headaches that begin in the afternoon

There are ways you can help prevent the common causes of eyestrain. Here are the most common causes and their remedies.
