Sleep ZM Fit Over Blue Light Glasses for Computer, TV, Gaming Improve Sleep by Naturally Producing Melatonin for Women + Men

Sleep ZM Fit Over Blue Light Glasses for Computer, TV, Gaming Improve Sleep by Naturally Producing Melatonin for Women + Men

Q: Is it really block 95% blue light as in the description?

why would anyone want 95 to 99% blue light blocking? blue is a prety color and if you remove the color from the spectrum you will greatly modify all colors and cant enjoy blue at all non light emitting blues will suffer and light emitting blue is completely lost and not sure if you ever see color wheel when you remove colors. 60% should meet and exceed the medical needs for eye strain and circadian rhythm. the real question is what wavelengths are your glasses? and next question do they have anti reflective film on 1 or both sides of lenses?

Q: What exact spectrum of blue light does this block? Is there a transmission chart?

Please see the new chart provided in the images. Sleep ZM glasses block an average of 99.9% of all light in the 280-510 nm "Melatonin Suppression Zone". It's good for blue light to suppress your Melatonin during the day - that's what helps you to stay awake. But we need to reverse this process at night before trying to go to sleep by blocking the blue light from our eyes.

Q: I bought a pair less than 6 months ago and one of the handles is already broken. Are these break resistant?

No they are not break resistant. U must also take into consideration that these are very inexpensive glasses that do work but are a bit delicate. I knew right from the start that I would have to take care of them. So far they've lasted over a year for me & still going strong. If ur interested in glasses that are much sturdier ur going to have to spend over $100. I did my research before buying these. Good luck!

Q: What size eyeglass case will these fit into?

Don’t think they’ll fit into most eyeglass cases..but they do come with a drawstring bag, cleaning cloth & box which would be ok for traveling but not so much in a handbag. They’re designed to go over prescription glasses..so prob size of regular sunglasses. But they’re not unattractive either. I’m very pleased with them. So if a pair of sunglasses fit in any of your cases these probably will too. Hope this helps.
