Since the thread is for food "or anything," I've got something in the latter category: Blue-light blocking glasses.
I imagine most of us are staring at screens excessively. By the end of the day, my eyes would be pretty bad. I already have to worry about my eyesight for other reasons, but having your eyes feel pretty bad at the end of the day is not helpful. Plus, I should reduce stress, also for healthy eyes, and worrying about your eyesight is not a way to reduce stress.
After Amazon lost the initial order (detailed in another thread), I finally received my blue-light blocking glasses yesterday. I am getting new glasses from the eye doctor and those will be coated to block blue light, but I had already had these ordered prior to my eye doctor visit and didn't see the harm in extra protection.
There is much discussion online regarding the harmful effects on blue light on our eyes. At minimum, it can disrupt sleep cycles. I haven't really noticed that as a problem, but all the time staring at screens does seem to do a number on my eyes. There also seems to be some debate over whether the problems caused by blue light exposure are temporary or permanent. I don't want to take the chance on the latter.
I've looked at these kinds of glasses before, but never got around to ordering them. I wish I had. I don't know if they would have prevented any damage but they certainly reduce eyestrain.
I received them yesterday and have been wearing them since. I still have some problems since I need glasses to see close and so there is still strain on my eyes trying to focus, but the discomfort at the end of the day is significantly reduced.
I got ones that claim to block 95% or better of the blue light. I have no idea whether that's true and no way to verify the claim. It does seem to help though. Hopefully, it's not a placebo effect. Blue light does not show up as white as the ads claimed. Some blue light appears less blue and maybe, kinda, sorta almost whitish, but not white white. In other cases, I can still tell the color is blue. And, in other cases, the blue is almost black. In the case of hyperlinks using the standard blue color, they appear almost black, which does make seeing them a bit more difficult. Also, my eMail inbox uses blue to indicate new mail and that shows up as almost black too. Fortunately, it's also bold, but bold and black doesn't stand out as well as bold and blue.
The world is orange-tinted now. Amber, really, I guess. It's not too bad. I can still tell white from off-white and stuff. I do work in printing so when I need to see exact colors, I just take the glasses off.
Lights aren't as bright. It's not quite the same as wearing sunglasses or polarized lenses. Clarity is still there. In some cases, things appear clearer perhaps because you're not being overwhelmed by the blue light. I don't know. They seem to remove some of the harshness of bright white lights.
Downside is that you need to keep the lenses clean. A little smudge is noticeable and annoying. The frames are not the best. There were plenty of reviews on Amazon on how easy they break. The plastic doesn't seem like a high quality plastic, especially not for the price paid. But for the apparent effectiveness of the lenses, they've been worth it so far.
Despite the color change, I often forget I'm wearing them. An amber-tinted world is less noticeable than sore, watery eyes.
It's also nice because when I drive home at night and it's dark, I can see better. Not with the glasses on, but with them off and wearing my regular glasses. My eyes aren't as messed up as before. And this is only day two of wearing these glasses.
So, yeah, I wish I had bought these (which have been in the "later" part of my shopping cart on Amazon for two or three years) sooner. So far, they really do seem to help.
