So good.

I llllllllove my Clyde Night glasses. I've worn them every night since they arrived and find it much easier to fall asleep. Really diggin’ the clear frames too, which makes it feel like they aren’t even there once you get used to the color shift. I’ll be picking up a pair of daylight’s ASAP.

Thanks JK! We are very excited to hear that the Night Lenses help you sleep and STAY asleep! Keep on rocking' the look!

These glasses help me sleep!

I have the same style in the day lenses, but I wanted the night version too, to be fully protected. So much more light at night, with all the light bulbs on, and these ones block it all out. I fall asleep within 10 mins now, instead of my regular 30 or so...And haven't been waking up at 3am like I used to. They have helped me become a morning person too, because I get my full sleep at night time. I wake up full of energy and ready to go! I also watch the sunrise first thing in the morning (good health tip) to get my circadian rhythm rocking for the day. This style is super comfortable and they feel like they are so well made. Not like the cheap, clear pair I bought before I knew better....Highly recommend these if you want to sleep better!
