Just because sunglasses may be knock-offs, it doesn't mean that they're going to be bad for your eyes. Sometimes sunglasses that are extremely cheap can have different opacity in the lenses, which causes problems with depth perception, but you should be fine with your fake Oakleys.
By having bad eyes.
No, 3D glasses are not bad for your eyes when used properly. They are designed to provide a comfortable viewing experience and do not cause any harm to your eyes.
Just is- in fact they are not bad for your eyes in any way! all the glasses do is filter light. they also do nothing to harm your brain also!cool huh!
Wearing the same glasses will not make your eyes go bad. It is likely that your prescription has changed and that you would see better with a new pair.
I would check with your doctor first.I wear glasses and I would not change unless she told me I could, I just do not like messing with my eyes like that if I am not sure, that I can switch to contacts. and my eyes are not that bad either
depends how close they are to your face (if light can get behind them) my friend has them and its not that bad but u can get new lenses from oakley or walleva or visionarylenses
Staring at the sun too long and wearing glasses when you don't need them
it wont harm you at all
Sounds like you may need glasses. Go get your eyes checked.
Well,it depends on how bad you pull your eyes because your eyes have been strained and they have to heal up and they may or may not need help to heal.
If you are using shutter glasses, your eyes may get tired if the glasses are not operating properly. Each side of the glasses take turns showing an image frame and a black frame at the same time. If the glasses are good quality and are properly charged, it should not be an issue. There is no evidence to suggest long term harm caused by 3D glasses.
I'm an ophthalmologist, so this is right up my alley. It is not bad for your eyes if the lenses don't have power in them, so if this is the case, then go right ahead! Truthfully, it is not bad for your eyes even if the lenses do have power in them, but doing so can cause symptoms such as eye strain, headaches, and fatigue.
