I was trying to buy blue light blocking glasses to help my eyesight. I always feel like my eyes are strained in front of my iPhone, tablet or even computer. Especially in front of my iPhone. I tried the one sold by Amazon's MODA which I find the amber too dark, the Gamma Ray GR E-803 too small and the Gunnar Inception too tight and hurts my temple. Cyxus isn't as good as Gunnar but seems to work and my eyes don't strain as much in front of my iPhone. It fits me well and I believe you can easily ask the optician to adjust the strap for you if you find it too tight. Speaking of blue blocking, I think Gunnar will do the job better. As you can see in the Gunnar vs. Cyxus comparison image below, Gunnar blocks more blue light than Cyxus. Cyxus lenses are too yellowish for my taste. I wouldn't recommend buying it unless you can't stand too much yellow on the screen. Weight: 21 g (0.70 oz) Front horizontal length: 14 cm Front height: 3.50 cm Side length: 13.50 cm It's always difficult to find the best fit for you online. Finally, I want them to come up with an explanation about the glasses, not a piece of paper telling you to rate them 5 stars.
