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.

These full block out glasses are the real deal. I put them on just as the lights come on, and I feel my body drop into rest and night mode. I wear them doing my evening taichi class and sleep so well not having to do taichi under fluro lights. They are really worth it!

Really good glasses. Fits with most reading glasses. 🤓

I now wear them every evening. I seem to fall asleep much quicker. (They do make me look like I'm trying to do an Ali G impression, though!)

Fantastic glasses. Fit over ny reading glasses when on computer in the evening. And also for around the house if have main light on. Look pretty good too.
