The quality of filtering the blue light from the screens makes it great

I highly recommend this for anyone who spends hours on a computer each day and already wears glasses. This completely blocks blue light and prevents irritation and soreness of your eyes. This will also prevent eye damage caused by years of screen time.

I bought these to help with glare from computer work. I tend to get headaches and I was hoping that if I could cut the amount of blue light, the number of times I get a headache would decrease. Have only used them about two days now. I can tell they help.

My eye doctor recommended I start using blue light blocking lenses at this years eye exam. I found these on Syght and decided to try them as it was much less expensive than lenses at the doctors office. They are easy to place on my existing glasses and do not scratch the lenses.

Love the glasses. I have had driving at night due to glare and when raining, impossible. I tried the glasses driving at night and they made a world of difference. I could actually see the road and no glare. There isn't anything I don't liked.

These arrived on time, well packed, professionally & as advertised. They are very light weight & work well nonetheless. The lenses are good, light & no bulky.

I loved it. I tested it for a few weeks. Without them and with them. When I use them I don't get headaches from the eyes when I play games for a while.

I have recommended these to a lot of my coworkers. And now that I am used to it, I don't even use computer without it ever again.

I have been having issues with computer eye strain. I where prescription glasses and was looking for a compatible clip on lens filter. Product is quality material and works very well. The lens easily mounted my glasses and has swivel to flip lens up vice taking them off. After 2 days of use, I found that I no longer experienced the eye strain and discomfort. For the price and convenience and effective, these are a highly recommend.

I got these as a gift for my mother. She spends a lot of time editing photos on her laptop, and have been having eye strain issues for a long time. These did the trick, and have made a huge difference. I definitely recommend these glasses if you are having issues with eye strain & prolonged computer use.

I'm a graphic designer and avid pc gamer so I spend around 8-12 hours in front of my screen everyday. These things really DO reduce eye fatigue. Build quality is excellent. Feel very high quality and the included case and micro fiber cloth is also nice. I would not hesistate to buy this again. If you're on the fence, DO IT!

As much as I hate to m admit it, my eyes feel great after wearing these all day when I'm on the computer. I'm a believer.

Just as expected. It works like the blue blocker glasses, but the quality on these are very good and sturdy. I've noticed less eye strain as I play online games, and the contrast was rough on the eyes. It also helps with converting all the brightness of many websites. They fit well and flip up when not in use.

I play a lot of Video games and I work staring at computer screens all day and I developed a bad twitch/irritation in my left eye. Since I wear glasses I couldn't afford prescription glasses. I decided that I would give these a try and I really like them. Only down side is they are much bigger than my glasses so if I'm not careful the SYGHT lenses touch my face.

Work quite well for my intended use. The nature of clip-ons that fit a multitude of frame and lens sizes cannot be perfect in all situations. I noticed the "clips" in my field of vision as well. As with most things of this nature it is simply a matter of adjustment. After a period of time goes by, you will no longer notice this and it will not be an inconvenience.

Don't buy Acer Led monitor unless you like going blind. The white's are way to bright and no contrast or brightness control. You can use the graphics card to control the contrast and brightness but your games will be very dim. These glasses save my eyes from viewing such a bright screen

Bought these to see if they would help with my headaches and now I almost never take them off. I'm in front of a computer 10+ hours a day and these are a huge help. If you have issues with blue light, give these a try. I'm pretty sure I'm going to be getting my lenses changed out permanently for these type of lenses.

These are really great! I don't know why, really, but I know my eyes appreciate whatever they do. I can tell the difference. I also like being able to flip them up instead of having to take something off. I wish there were a lighter design, but I'm not an engineer, so I can't really criticize, I guess. Still, it's great that the pinchers which hold it to your glasses have soft material, so I feel assured it's not going to harm my lenses. Also, they are stylish.

Fits over my prescription glasses perfectly, easy flip up, CRYSTAL CLEAR is good choice for me - not to dark and doesn't severely change color perception. I must say, the blocking effect advertised does work and I'm able to fall asleep faster than not wearing it after working with my computer for hours. Really worked for me, and this was a good buy!

This is the 3rd pair of different clip-on blue blockers that I have ordered and finally received the one that is just right! The first pair was too heavy, the second didn’t flip up and were too small and this one is a clip on that flips up, that is light weight, covers my glasses, and does an excellent job of blocking the blue light. Yipeeeeeee! These are just right! Thank you

Convenient to just clip them on my glasses. They don't get in the way of my vision. Much cheaper than buying dedicated prescription computer glasses. I sit in front of my computer all day. My eyes felt a sign of relief once I put them on. Nice design and nice carrying case with tool. Highly recommend.

I'm a person who's always looking at a computer monitor, so I can say with confidence that these glasses work pretty well. Better than I expected. Noticeable difference after hours of computer use in a dark room. Significantly less eye strain and my eyes don't tire. Pretty good. The clips are surprisingly unobtrusive. Read some of the reviews and was worried about them as they do look pretty large in the picture. But at least for my glasses, they didn't get in the way at all. Overall, they do what I want them to, and are good computer lenses.

Yes, these are a little geeky but WOW!!! I've been spending an average of 15 hours a day in front of various digital screens and my eyes were very fatigued. So out of desperation I gave these a try and I regret not getting them years ago. My eyes are less fatigued and I'm getting a better quality of sleep. I love them so much that I bought a second pair as gift. I highly recommend.

I bought these for work. I really like these. So much so that I take them home every night and watch TV with them on. They really cut down on eye strain. Yes, they are bit heavy and my coworkers tease me and say I look like an accountant. Don't care! They do exactly what they are supposed to. Between these and the humidifier at my desk, my eyes are grateful.

I Highly Recommend These clip ons and This Company. Thank you syght!

These glasses can clip into any other existing glasses. For those that may suffer from eye pain or problems due to the blue and white lights from LED monitors, this may alleviate the pain and make it bearable to view again. Everything about the glasses work as advertised, I can't find any faults in the simplicity of this item.

These Glasses are Top of the Line and I would recommend them to anyone looking for this type of Glasses.

These are excellent quality. They come in a cool case with accessories (cloth & bag). And when I put them on, I could feel my eyes relax. They do what they say they do, This is an excellent product and so very well worth the money!

I've owned these glasses about 6 months now and as a software developer and generally as someone who spends a lot of time in front of a computer, these filters WORK. My eyes are so much more relaxed and it's so much more pleasurable working now. Before, when I sat down in front of my computer, I had a timer in my head that would count down before I had to just stop and look away to avoid "dry eyes" and headaches. Previously I tried tinkering with the computer brightness, backgrounds of coding windows, etc - those made minimal differences and I still always left the computer "fatigued" from eye strain. These filters have changed all of this and to be honest, for $30 it's a STEAL. I am probably just going to buy another one so I have a pair in my bag when I travel and one for home. Highly recommend.
