I have noticed getting a lot of eye strain while spending time using my computers for long periods. I don’t remember having much of that issue in years past. So some thing or things have changed.
I spend a lot more time at the home computer in blog writing, CAD (Computer Assisted Drawing/Drafting), photography editing, and other screen intensive tasks. I did the same at my office before I retired. I had a desk job.
The first thought are my eyes. Definitely the number one suspect. I admit I am overdue for another exam. I wear glasses and at age 70 and above, the eye lens is less flexible and the tiny muscles have to work a lot harder. I really need another pair of glasses especially for the computer screen and desk work in general.
There is another big issue. It’s screen brightness. Monitors have significantly changed. All mine are now LED illuminated. Lighting is even over the entire surface and intensity levels can be set very high. What is happening is my iris muscles are struggling to dial down to tiny openings to compensate for over brightness.
I now usually sit in a darkened room. The screen is the brightest lighting in the room. That’s not real good for the eyes. My work office had a window wall behind me and constant overhead lighting. Lots of ambient light keeping my irises dialed down.
I know my ares are no longer very good at dialing down. Just walking outside on a sunny day is, for quite a long time, a blinding experience. They slowly compensate but sunglasses are a real need for comfort.
I checked my brightness setting on the screen I am currently using. The display was sharp , crisp and uh… very bright! The brightness setting was around 75 percent. Hmm… that seemed to be pushing it a lot for long term web browsing and text writing.
I dialed it down to 50 percent and immediately noticed an improvement in viewing comfort. Yes, it IS dimmer, but that is a very good thing. I have no problem viewing and the visual “pressure” instantly went away. A pressure to which I wasn’t paying adequate attention.
A suggestion I’ll share. Check your monitor settings. A brightness over 50 percent is probably too high. If you are like me and spend a lot of time at the screen, turn the intensities down on every control. Use more room lighting but avoid glare on the screen. The monitor shouldn’t be the brightest light in the room.
My eyes have thanked me.
