First off: I'm not an eye doctor; I'm just a guy who spends a lot of time in front of a computer! Double-check anything I'm telling you here with your optometrist or ophthalmologist before you do anything else with this information.
Secondly: This isn't a paid post; I'm not receiving any kind of compensation from it. I'm just a fan!
The last several years, I had been suffering from moderately severe eye strain while working in front of my computer all day. Even though I have a nice setup where my monitors are set up a a little over two feet away from me, after working for a solid hour two, my eyes would kind of "cramp up," feeling fatigued. I'd need to either close them for a couple of minutes, or at least spend time intentionally looking at a wall or object a longer distance away (e.g. across the room), in order to let my eyes recover enough to resume looking at my monitors and continue working.
At my most recent optometrist visit several months ago, my optometrist -- shout out to Dr. Staci E.! -- prescribed "Eyezen" glasses. The glasses that I got are designed specifically for "near-distance" vision: Things that I look at far away through them are somewhat blurry; but the glasses produce really excellent clarity when looking at my two-feet-away computer monitors!
These glasses have made a very positive difference in my day-to-day job. When I sit down at my computer, I swap out my "everyday wear" glasses for the Eyezen glasses, which I just keep at my desk. Wearing the Eyezen glasses while working, my eye strain symptoms have mostly disappeared! I no longer get eye "cramps" or fatigue that forces me to stop working to "un-strain" my eyes on a frequent basis.
When I get up from my desk, I swap my Eyezen "computer glasses" (as I think of them) back out for my daily wear glasses. This is obviously an extra step, but I haven't found it to be at all onerous. The cost has definitely been worth the benefit.
As I hadn't previously even been aware of the existence of specialized "near-distance vision" glasses, or Eyezen glasses, I figured I'd share my experience to spread the knowledge! My new glasses have really helped me; if you suffer from eye strain while working on a computer all day, consider asking your eye doctor if they might be a good option for you, too.
