Why do car lights dazzle me more now that I have changed my glasses than before? (discuss.tchncs.de)

Until 2 years ago I started wearing glasses, and as soon as I started wearing them I noticed an immediate change in my perspective of the reflections, before it was not especially annoying, it was just that mainly the reflections of car lights were too noticeable to me, and a month ago I changed my glasses again after all that time and now I really wouldn't dare to cross a street at night because the reflection of certain car lights is too noticeable, it's basically as if the brightness of my sight lowered and focused only on the light of the car, basically I see like two suns in front of me when I have a car in front of me.

I am really worried about this, is it reversible?

I've worn glasses my whole life and never experienced what you're describing, but I wanted to point out that lenses come in many different materials and coatings. I once got glasses with some coating to reduce blue light, and experienced constant blue lens flares whenever sunlight hit them. I just went back to the optometrist and described the problem, and they got me replacement lenses without the problematic coating.

I assume not everyone experiences it the way I did, otherwise those lenses would not be on the market. The optometrist was aware that the lenses would have a blue tint to them due to the coating, though, so it was easy to know what to change.

TL;DR: Talk to your optometrist, they might know what's wrong and fix it for free.
