fit perfectly over my large ray ban glasses. They are lightweight and don’t interfere with how my glasses or hearing aid sit.
I have had these for a long time. I mostly wore them outside but vision kept getting worse. Then I noticed I could see better without them so they sat on my bookshelf for a long time. Then I read that these could help me sleep better if I used them while watching TV at night. After a few days I started to notice that within a half hour of use I would get a low grade headache. I stopped using them for a few days and then started up again just to make sure it just wasn’t a coincidence. Yep within a half hour the headache started to come on. I did some research and found out that the claims for blocking blue light may not be true but if it works for you and you have no side effects I say go for it. For me they did not do anything but make things worse.My wife loves those glasses also looks good on her.
