Its hardly ever used and its lenses have started to flake. Is there any fix to it or shall i sell it? There is a signature on the lense too, anyone knows who's signature is that?
You can get replacement lenses. The signature is Sebastian Loeb. The delamination most likely is from sweat or other contaminants not being washed off after use.
Unfortunately, there's no way to fix that delamination without hurting the lenses protective properties. There are videos on youtube where people put some tape on them and then take away the most external layer. They look fine after doing that but sadly have lost some of their capabilities to protect you. Ur eyes definitely deserve better. Replacement lenses are a great option. Fuse are great, kinda in the middle not cheap, not too expensive, amazing price-benefit balance.
