Frequently Asked Questions

How does it work?
Check out our Technology page.

Do I need these if I already have F.Lux, nightmode, smart bulbs, computer glasses, etc?
Red is how we help you block over 99.8% light in the melanopic spectrum. If you are OK with solutions to filter out on the order of 50% (i.e. letting in >250x more light that interferes with sleep), then no. Otherwise, buy Carbonshades. 

Why >99.8%?

So you know it isn't 97% or 51%  being rounded to 100%. 99% might be enough, but better safe than sorry when it comes to your health.

What is your return policy?
We have a 100% Satisfaction Guaranteed return policy that lasts for one (1) year from the date of purchase. Contact us at if you would like to request a return or exchange.

Do you have prescription glasses?
Unfortunately we do not currently offer prescription or reading lenses, however they are certainly on our radar. We are also looking into overglasses and clip-ons as potential future products. If you are interested, please let us know via social media or email, and subscribe to our mailing list so we can let you know if we release them!

How do you ship?
We ship all of our orders from the United States with USPS First Class or Priority Mail to ensure they arrive in as timely a manner as possible. For most orders, we will dispatch your package within one business days of receiving order confirmation, after which it will take 1-3 days to arrive at most US addresses and 3-12 days to arrive at most international addresses.

I live internationally – will I need to pay customs? 
We try our best to avoid incurring customs fees, but occasionally local post offices can hold packages until a fee is paid (particularly in Europe). If this happens to you, just let us know and we'll take care of it!
