Yes, they really work. Clipped them onto my Eyewear and wore them all day. They really blocked out the blue light. The visor diminished my eye strain and fatigue after a long day at the computer. I find them soothing to my eyes and I can tolerate the LED lights. Hate office lights love this product. Recommend. 💖 💖 💖 💖 💖

I have been using these clip-ons while at the computer for a couple of months now. They are really helping to cut my eye strain.I only gave a 4 star rating because they are so much bigger then my glasses they have a hard time staying on.

I used these lenses for a couple of months while working and they work well for their intended purpose. After a very few minutes, my brain adjusted and I saw white as white again, but without the harsh blue cast produce by LED backlit monitors. I eventually found some software to accomplish the same thing without the need for clip-on lenses on my glasses, so I stopped using them at work. Having them laying around, I decide to try using them as night driving lenses. I have found them very effective for this purpose. The tint is very light, so it doesn't feel like I am wearing sun glasses at night, but they do perform very effectively at cutting the annoying, piercing blue light that comes from the LED headlights of may luxury cars these days.

They fell apart after a few weeks, threw them in the trash. I went to an optometrist several times to tighten them, but finally the screws did not hold at all. I went to a repair place as a last hope, but they just laughed, saying: 'oh, these are disposable'. It was a frustrating experience. I do not recommend this bad quality product.

I work long hours with three monitors. I was finding myself taking breaks too often, was tired and my eyes always wanted to close. I would push myself to work at least 2 hours before taking a break. My breaks were sometimes too long and I found myself working from morning to night but only for 6-7 hours. I figured it might be eye strain, so I purchased these thinking that they will pay for themselves if they help me stay on the monitors longer. Today was my 2nd day with them and I worked a full 10 hours with only one long break for lunch. I'm still here typing this out before going to bed. I know I couldn't do it without these shades. My kids tease me but I'm no longer squinting and feeling tired!! Thank you so much for selling these!!!!

Selected these because the nominal dimensions (lens height, width & shape, and inter-lens distance) were a perfect match for my frames. However, the clip-ons don't snug all the way down to perfectly cover my lenses due to lack of clearance over the top bridge wire of my frames. In principle, this might be corrected by re-shaping the wires forming the "clips".Otherwise, the clip-ons work as promised. When viewing my laptop's screen, the filtered light is far more restful on the eyes.

I really wanted to LOVE these clip on's, and I do use them all of the time because of the health advantages, but they are WAY too big for my glasses and my little face. I fight getting them on and off, which does discourage me from using them. I hope they last a long time because I will NOT buy another pair that doesn't offer a smaller size.

I work in IT, go to school, and sometimes I'm on my computer in my spare time as well. I remember that there were lenses that block blue light from being a strain on my eyes and figured I'd go to Amazon to find a clip-on style. I decided on these since they had a fair price and seemed good based on the reviews.I've been using them for about a month, and I've definitely noticed the difference in eye strain. One thing I was worried about was quality, but they're decently made since I haven't had any problems. They also come with a case to place them in (not big enough for glasses, just the clip-on lenses), along with a small cleaning cloth and replacement grips. My glasses are just barely smaller than the clip-ons, but that's more of a glasses problem and not the product.Overall, I'd say if you're looking for a great pair of clip-ons that filter blue light, then I would recommend these. It's almost essential if you work in IT like I do, or you're in front of a computer screen a lot. If you need the orange-colored pair, then you might have to keep looking.
