Review: The best 99.9% blue light blockers on desertcart - They explain well on the packaging why other blue blockers are a gimmick and give the exact Nm light that these block which are in the blue range... Don't buy stupid 'transparent' blue blockers because they just don't work.... They have to be yellow or amber orange tinted in order to block blue light effectively! These are great and sporty stylish too! You'd look like a bio hacker extravagant with these... Pricing is THE best i have come across on desertcart or anywhere!! Go ahead do yourself a big one and invest in these,, my sleep has improved significantly
Review: Best and unique product - Super feeling and stress free to eyes when wore in artificial lights in night. Protect your eyes from artificial blue light and feel the changes in you. Must recommended product.

## Questions & Answers

**Q: Do these glasses really help you to sleep better? I already have my iPad with night light on so the light is more yellow**
A: They helped me. I've found they block a slightly different spectrum than the Amazon kindle setting and then some other software I tired fur my phone. I did not do any testing to see if there was a noticeable difference between the glasses and software blocking. To me, the glasses are much clearer than the software. Though I think the glasses are less convenient than software.  But I also have lots of other dim sources of light around the house that the glasses can help with.  If you are in a dark room with basically only the iPad, you may not notice any difference.

**Q: Can these be worn forvdriving at night?**
A: No, these are not right for night driving, they block too much light. Do a search for ‘night driving glasses’ to find something more appropriate.

**Q: Why have you not added more info related to the exact product dimensions and potential day time use?**
A: Hello M. Hayashi,Thank you for your interest in our nighttime eyewear.It is a bit challenging to describe the dimensions but I'll give it a shot. The front is 5.5 inches across by 1.625 inches high. From the bridge of the nose to the tip of the arms is 7 inches.There is no such thing as "one size fits all" when it comes to glasses and I fully understand if they don't fit properly. We have a "no hard feelings" policy when it comes to refunds. If you are not 100% satisfied with your purchase just let me know, I'll make it right :-)As for day time use, they will help in situations where you need very fine visual acuity such as sharp shooting. However they are specifically designed for nighttime use. I do not recommend them for driving due to color distortion nor do I recommend them for daytime computer use. Blue light is beneficial and even necessary in the daytime, but highly disruptive at night. Thanks again for your interest

**Q: When will these be back in stock?**
A: Yes, they will.
