BluBlocker Small Rimless Clip On Sunglasses 56mm width lens

I bought these to block blue light when working on my computer in the evenings. Sadly, they don't suit my purpose, as they distort the colours on the screen so much that I can't use them. So if that's what you're looking for, I don't think any of the yellow light-blocking specs are going to work for you unless you're just working with black&white text.However, the pros are:- good size coverage for my small prescription reading glasses.- Lenses don't get in the way of view or bump against your face.- Clips attach firmly and unobtrusively to spec frames (though a bit stiff and fiddly to attach)

I am sensitive to blue light so I bought these to wear at night in my house. I am going to get the larger ones since my regular glasses are wider, but they fit great. I plan to use these in my office to block out the light of the computer. I held my breath for a moment when I saw that they arrived in a bubble envelope with no packaging. The box inside was crushed...but because they are BluBlockers, there was no damage to the actual lenses.

the clip mechanism is super....works well, easily, and doesn't hurt my glasses. The blue-blocking is good; I can feel my eyes being less fatigued. The only thing is that these lenses don't deliver as good contrast as the UVEX ones do....but I'm using these rather than those because these are more comfortable on my face.

They work great to block the blue rays from my Kindle reader, however they already show an area on the front of the glasses where they are scratched. I have been careful to not lay them down on their face, so they are very delicate. I've only had them a week. Not a good sign for long usage.

I can really tell that I have these on. They fit my smallish glasses well, even though the clips set the top of the clip ons kind of far from my lens. This may be why I'm having trouble getting used to them. They work as advertised, though, and really make light coming from the Fire tablet amber. I think I'll stick with them.

I love the concept of these, and they do help with the blue light issues, but when on my glasses, I can see the black hooks that hold it in place. It is very distracting and makes me feel like I am going to go cross-eyed. Not the best product.

So, I returned the product but still am giving it 5 Stars.The reason for the return is something I'll note for others but in no way is a negative on the product.I measured the dimensions of my glasses and compared to the dimensions given for the BluBlocker product. Those dimensions were good so I ordered the Small size. However, having never used clip-on sunglasses I failed to think about the space taken up by the actual clip-on piece so that after I attached them to my glasses there was about 1/2 inch of uncovered space on my glasses at the bottom. I have returned and ordered the larger size.However, for the few minutes I was looking at my computer monitor with them I did see the color change that I have read indicates blue light blockage and my eyes immediately felt better.

The clip is very bulky; it obstructs your field of view. The lens also sits pretty far from the front of your glasses so it doesn't block much. Buy a much bigger size than your glasses and it might be fine, assuming you won't mind the black bars in the middle.
