Blue Light Blocking Test

• We use the blue light torch to beam the sensitive area of blue light testing card through normal lens,the part of testing card beamed by the torch has turned purple.

User questions & answers

Question:	Why does only one pair have one blue lense? I thought I paid for four blue lenses
Answer:	According to the Description, it does prevent glare: Beyond blue light blocking our computer glasses have several coatins to improve your quality of life UV Light Blocking (100% Blocking UVA, 100% Blocking UVB) Anti-Scratch Anti-Reflective Anti-Screen Flicker Anti-Glare Anti-Fog Anti-Oil (Fingerprint Resistant) Electromagnetic Ray Blocking
Question:	Mine failed the blue light test. Has anyone ever had them replaced and had the replaceable pair pass or am I wasting my tome
Answer:	6.1 x 2.2 x 0.9 inches are the dimensions of the small size6.5 x 2.2 x 1 inches for the regular.I'm not totally sure if the two size options were available when I purchased mine - my spectrums read 6.5''. I assume I bought the regular. You'd want smalls for youth or smaller head size based on this, regulars for adults. That being said, my glasses aren't at all "snug," in fact the arms feel pretty generous. They stay securely on my face, and I run a medium women's head.
Question:	Are these non prescription
Answer:	DEFINITELY not! There actually is no tint at all, instead you will have all of the blue light blocked and nothing else, this eliminates glare not only on a screen but also if you drive with them. The best way to describe it is if you look at your computer screen you will see a yellowish haze where you usually would see white, yet not too much so you cant tell its white your looking at. This is easy on the eyes and soothing to look at for long periods of time compared to not having them at all, I tend to wear mine all day. You will never get that dry eye that your eyes produce tears to try and compensate for.
Question:	What are the dimensions of the frames
Answer:	While our glasses are tested to block 100% of UVA and UVB sunglasses have additional protection filtering down the total light that enters your eyes which can still be harmful. I would not and cannot recommend our glasses in place of sunglasses for daily use. Though they would be better than nothing if that is your only option.
