They fit perfectly over my prescription glasses. They are light and comfortable to wear. They certainly make my eyes feel much more relaxed when I read at night. Very impressed!

They were a success fitting over my own prescription glasses. Using them when under bright kitchen lights

I even wear these on my winter bike rides to and from work - and it's delightful not having the glare of oncoming cars now, in addition to knowing that it helps my circadian rhythm and prepares me for a good night's sleep

These fitter glasses were bought, along with the red lenses, because I have severe sleep problems. I use these when it first gets dark, & then progress to the red lenses about an hour before bed. I have their red globe in a lamp in my bedroom, & read for a while before trying to sleep. I believe I am falling asleep quicker than before since using them. They are a better fit than my old, cheap amber fitivers bought years ago from a different company. Thank you for a great product.

I wear the glasses for at least two hours while watching TV or using the internet on the phone. They have proved to be excellent, giving me better sleep. I am well pleased with them.

These fit snugly over my reading glasses when using my computer - or other close-up 'jobs' like reading - in the evening... or for using without the reading-glasses when watching TV (where there's inevitably some colour distortion - bright blue skies look green-ish, but you soon get used to that).

Noticeable impact on sleep quality. Less mental fatigue.

Great product.

I love these sundown blue blocking glasses. I previously had the red ones, but found them too dark. These ones are great to wear when the sun goes down and until I go to bed. They make it easy to watch any screen, and I am much more relaxed before bed.
