Question 1

Do these glasses really help you to sleep better? I already have my iPad with night light on so the light is more yellow

Accepted Answer

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.

Question 2

Can these be worn forvdriving at night?

Accepted Answer

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.

Question 3

Why have you not added more info related to the exact product dimensions and potential day time use?

Accepted Answer

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
