I bought these to assist with resetting my circadian rhythm as I have experienced poor sleep for the last number of years. I wear these as soon as the sun goes down until sleep time, whether I'm on a device or simply walking through the house with lights on. It has helped immensely. My usual 2 hourly wake ups turned into 6-7 hours sleep straight. The effect was immediate. So glad I made the decision to purchase these.

Arrived on time. I really like how light they are. My eyes feel a lot less tired when I wear them.

These are the best, no doubt. My wife tried a different brand and it distorted the colors, but these don't. They block the blue light but everything is still clear. Highly recommend.

The UNIVERSAL size does not fit over my prescription glasses - not high enough and awkward placement of temples. Wish they came in different sizes; at least two like S/M and L/XL for the lens height. Also the temples design is not comfortable. They press too hard against the scull and cannot be adjusted to fit behind the ears.

Glasses work great. Fit over my prescription glasses perfectly

I have been wearing these glasses every night since I received them, and I have been sleeping well. Before that, I would often feel a bit 'buzzy' when it was time to sleep, after being on my laptop all day. I plan to take these with me overseas, to use on the plane because the screens are so bright, and to help me with my circadian rhythm. They also fit well over my glasses.

Though relatively sturdy the plastic feels cheap and they didn’t fit over my glasses, perhaps they are in need of some clearer dimensions on the name of the product or so. The lenses themselves work fantastically however, they just just didn’t fit over my glasses

Hands down the best purchase I have ever made to aid in resetting my circadian rhythm. My entire system calms down and prepares for sleep. Thank you for such a remarkable product.

I have noticed a difference within a week and now off my sleep medication.
