BluBlocker Black Viper - 2703K

They Work !I am delighted to be able to get the fabulous Blublockers again. Thes sunglasses are without daunt the best I have ever found! Have been wearing them for years- got them on qvc years back but then they stopped so I am really pleased to be able to buy new ones! Mine are getting more than a bit the worse for wear ! Would recommend to everyone who wants Good Subglasses!

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).

Excelente estilo y visibilidad única, muy recomendado.

El color no es muy agradable al principio ,pero después de unos minutos se acostumbra la vista ,todo se ve nítido pero para cubrir de los rayos del sol siento que no protege nada ,solo los uso para cubrir del aire ya que uso lentes de contacto y los laterales están protegidos cubriendo todo alrededor

This is a qualified 5 star rating. I have worn this style for years. I'm a real fan of the sidepiece design as it allows for side vision and the wrap of the frame gives a close, light blocking, fit. I'm pretty light sensitive and find the lenses superior to many other pairs of sunglasses I've owned. My only small complaint is that I find I have to replace them more often that I would like as the rubber nose pieces break off long before I've worn out the sunglasses.
