Review on 👓 Livho Blue Light Blocking Computer Glasses: Say Goodbye to Eyestrain and Sleep Better - Designed for Women and Men by John Espindola

These glasses are fantastic. The only reason I give them 4 stars instead of 5 is because of a small defect I had. The right rosette on my glasses wouldn't screw in properly (I'm not sure if it was the screw, the hole the screw goes through, or the rosette itself that was defective). As a result, the screw attaching the nosepiece to the glasses fell out once a day or more, which in turn meant the nosepiece fell out. The first few times this happened I just screwed it back in as best I could, but now I've decided to just remove the nose pads entirely. I don't mind that (nose pads aren't particularly important to me anyway), but others like it, and this review is for others, so I decided to downgrade a star for this small flaw. The reason these glasses are awesome is because they: 1. Look good. I received the bronze version.2. Very difficult. I bent the frame on purpose to make it more comfortable after removing the nose pads, but I certainly wasn't afraid that something might break.3. do your job They don't let through a noticeable amount of blue light. I have keratoconus so I have to wear rigid gas permeable contact lenses to keep the disease under control. In keratoconus, the light seems to spread out more, creating more halo effects and the like around light sources. Since blue light moves more than the rest of the spectrum (at least to my knowledge), blue light blocking should block the worst offender when it comes to light sources that create nasty halo effects. So I bought these goggles to protect my contact lenses from the wind and what the wind brings and to mitigate some of the uncomfortable light effects associated with keratoconus. These goggles do the job pretty well. For those of you wondering if there's a noticeable effect on color when you wear glasses, there certainly is, but it's not uncomfortable at all and is only noticeable when you compare colors with and without glasses. This is most evident when looking at white, where pure white becomes the white of diplomas (and many books) and the paper has a slightly yellowish tint. Thus, pure white looks like white paper. However, these glasses definitely do not block 80% or even 40% of blue light. They almost certainly only block 12-20% of blue light. If you're looking for something that blocks large amounts of blue light before bed (so as not to upset your biological clock), get something that distorts your color vision a lot more, even with yellow lenses. If you're looking for something to make all-day screen-watching a little more bearable, these glasses do the trick, and they worked for me. Perhaps it is better to buy computer glasses with magnification, since the main cause of screen eye fatigue is not blue light, but the fact that when we look at screens we only focus on something very close and the magnification that comes with it B .of computer glasses, disturbs that focus just enough to not strain your eyes. In general, my glasses arrived with a small defect, but I am very happy with them. They fill a niche need (because they don't block as much blue light and also don't have magnification) of people who want to wear blue-blocking glasses all day that don't distort color vision on things that are uncomfortable. Wise and have no potentially confusing magnification. They won't help you sleep too much at night or completely reduce eye strain from viewing screens, but they will make a small (but noticeable) improvement in both things. If that's all you're looking for, this is a good option.
