BluBlocker, Black Viper Sunglasses with Scratch Resistant Lens | Blocks 100% of Blue Light and UVA & UVB Rays | Gender Neutral - for Men, Women & Everyone | Blue Light Glasses | Sunglasses | 2703K |

I found out I need to protect my eyes from the Sun. These look great and seem to do the job well.

My husband says, “I’m very happy with these sunglasses. It blocks the sun and makes my vision much more clear cut. Also, it very comfortable and makes it easier to drive during the day.

As advertised. I have dry eyes which are sensitive to light and air. The side shields help with both. I have two pairs of these so I am never without them. Well made and live up to the hype. Would highly recommend.

The lenses are awesome they really do help…but the nose pad fell with in a week

The Viper model is clearly high quality, well packaged and fits very well (I am a 5'1", 125 lb female). I bought them primarily to wear after 8 pm to block blue spectrum light primarily from HDTV, smart phone and computer screen, as evening blue spectrum light very effectively keeps me awake. If I need to read, I wear the Vipers over my reading glasses -- Vipers are not designed to wear over, but my reading glasses are small enough that it kind of works OK. I might order a pair of BluBlocker clip-ons later.My circadian rhythm usually has me beginning to feel slightly sleepy about 8 pm -- without the BluBlockers, I would get a "second wind" by about 9:30 pm and find it difficult to impossible to hit the hay by 10:30 - 11:00. Instead, it was oh so easy to stay up until 2 - 3 am. This wouldn't necessarily be a problem but I have to get up a 6 am to go to work! And even on weekends I am trying not to give in to my tendency to want to sleep later (apparently better sleep hygiene to wake at similar time each morning).Wearing these BluBlockers is a subtle effect, and combined with taking one or more sleep-inducing nutrients at 10 pm (Natural Calm and/or L-Theanine and/or Lactium), the strong "second wind" is almost non-existent. I find it much easier to get to sleep between 10 - 11 pm. To arise by 6 am, I also use Gullwing's Sunrise System Lightbox model 320. It is a combo alarm clock / dawn simulator / 10K lux lightbox. 15 minutes of dawn simulator plus 10 minutes at full 10K lux makes it a lot easier to get up (I've never been a morning person).

I have been wearing BlueBlockers for years. For a while I couldn’t find them but now I can. The world looks better through these sunglasses; natural environments in particular really pop. And this style looks good too, but honestly I am more interested in how the world looks to me when I wear these than how I look to the world. This particular model is very cool looking but I like it because it keeps light from getting into eyes via any route other than through the lenses, which protects the eyes more but also enhances vision in a way that you have to experience in order to appreciate it. I will never not have a pair of these. I give five stars for every category except value for the money; the non-polorized plastic versions are a lot more expensive than they used to be and the polorized onrs are expensive as sunglasses with glass lenses. But I a still buying them and always have a spare pair handy for whrn my primary pair gets lost.

Good fit work well

I put purchase these blue blocker glasses reduce my exposure to blue light at work during long night shift hours under fluorescent lights and in front of a computer screen.My initial reaction to these classes was that they felt pretty cheap, physically speaking, for the price.Upon wearing them, they did block a lot of the blue light, as evidenced by blue colors often being green or some dark color, but there were still things I looked at that were blue in reality and showed up blue with these glasses, which made me question just how much blue light is blocked by these.The description of the website does not say what percentage of blue light these glasses block out. Doing some research online I read suggestions that they block about 60%. I can’t say for certain how accurate that is, but there are other glasses out there that block higher percentage and may fit closer to the face than these.Depending on your needs, these may work for you or they may not. For me, I’ve returned them.
