BluBlocker Men's Official Viper Sunglasses Large Black

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!

Very good pace of kit Id happily recommend them great for headache because of the blue light blocking as well of the UV blocking

Love the comfort and fit. Completely blocks blue light. I've bought 3 pairs of these. They fit my small head and also my husband's larger head due to the rubber on the inside of the arms and bridge of nose.

Brilliant sun glasses

Excellent sunglasses, the clearest & lightest I've ever worn. The 2 rubber flaps which fit the sunglasses on your nise

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.

I’ve purchased 2 pairs just so I have one as a back up. These are the best sunglasses I have ever owned! Totally blocks out blue light and great coverage. I can actually stand outside in the hot Hawaiian sun and not squint at all. The size and weight is perfect too. Totally satisfied with the polarization and it’s very durable. Great value! Try one!

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

Mi idea era que los lentes me protegieran al 100 del sol...pero oh sorpresa...a la hora que me salgo...sigue el sol fuerte y el grado de ayuda fue poco....entonces...no me gustó el resultado..esperaba más..y resultó poca ayuda..pero bueno...ya encontraré unos que si protejan del sol.
