Blue light from digital devices can be real problem if you educate yourself youll find scientific proof

These have a clip to clip onto your glasses and 2 feet will touch your lenses

Work great if they had some kind of anti reflective coating theyd be 5 stars if you have light coming from behind you can get a noticeable reflection on the lenses

The clip mechanism is pretty flimsy so i would be pretty careful with it

Overall these are a cheap alternative for those of us who cant afford prescription blue filter glasses

They work great to block the blue light but i find them hard to attach to my glasses and the black part of it that attaches to your glasses is too big

The glasses seem heavy to me and definitely not worth the money

When you flip them up things will look more blue than before momentarily as your eyes adjust
