I've worn blue light glasses before but Ocusleep is on a whole nother level! I'm literally on my phone all day &, of course, I have issues with sleep. Something that helps me to fall asleep is reading a book on my phone but being on the phone before bed causes issues with me waking up multiple times throughout the night, which leaves me feeling tired & cranky most days. When I had the opportunity to try Ocusleep through a free sample program I was super excited as these glasses are specifically made to wear before bed. I was a little nervous about the tint but after a minute (or less) I don't even notice it. I have the size small glasses & they fit me perfectly! The glasses are incredibly comfortable to wear, are lightweight but sturdy & very well made. I noticed an improvement in my quality of sleep after the second night of wearing the Ocusleep glasses. I actually fell asleep even faster than usual & I was able to stay asleep for 6 consecutive hours. A huge improvement from two to four hours of sleep & then having trouble falling back to sleep. The longer I wear these amazing blue light blocking glasses the more my sleep quality is improving. I wake up less throughout the night (no more than one time) & even sleeping straight through the night most nights. Now I wake up feeling well rested & refreshed each morning, which is a blessing! I highly recommend Ocusleep!
