Does staring at your Mac’s screen all day give you eye strain? Yeah, there’s that whole LCD and blue light problem to worry about and it’s not like we don’t have too many devices with LCD screens, right?
A quick Google search can reveal plenty of options to block blue light but there is more to eye strain than LCDs and blue light. Sometimes just staring at the screen for too long can cause other issues. Thankfully, there is an easy fix.
Yes, the 20-20-20 rule to prevent or reduce eye strain is a thing. How much of a thing? For many, it works well, but you need to be conscious while you’re staring at the Mac’s screen or have a reminder.
If you find yourself gazing at screens all day, your eye doctor may have mentioned this rule to you. Basically, every 20 minutes spent using a screen, you should try to look away at something that is 20 feet away from you for a total of 20 seconds.
That seems reasonable enough. What about the reminder? Yes, there’s an app for that. It’s called EyeDrop and it’s about as inexpensive as apps can be these days. Also, it’s not a reminder in the typical sense with a beep or alert or obtrusive noise.
EyeDrop helps you using the 20-20-20 rule by dimming your screen every 20 minutes for 20 seconds. This entices you too look away from your screen. The amount of dimming is configurable. Once it is dimmed, it can be easily cancelled at any time by double-clicking anywhere.
Well, that’s different, but seemingly very effective. If you can’t stare at your Mac for half a minute, then stare at something else in the room that is farther away. EyeDrop has some configurable settings, though. The actual intervals can be set to 10, 20, 30, or 60 minutes of time, each followed by 10, 20, 30, or 60 seconds of dimming the Mac’s screen.
Easy peasy, right?
There’s more. The interval resets automatically after sleep or when the Mac’s screen is locked (for example, if you step away from the Mac for awhile). The dimming is configurable, too– low dim, medium dim, high dim (ostensibly so you don’t cheat). And, EyeDrop works on Macs with multiple screens.
Easy to set up and configure. Easy to use and mostly unobtrusive. Inexpensive. And if you need to stand up to focus your eyes on something 20 feet away, probably good for your overall health, not just eye strain.
