Okay, let’s get realistic. If money is tight or your prescription is new, you have one temporary trick: tilt your glasses slightly. Seriously. Just push them a millimeter up your nose or angle them down. Changing the angle of the lens changes how light bounces off it.
It’s not a cure, but it’s a cheap hack for that one moment in the supermarket checkout line when the overhead lights blind you. Also, keep your lenses super clean. A greasy lens is a glare magnet. Clean lenses = less glare, even without the fancy coating.
