When looking through the front screeen my vision is somewhat distorted due to the outer surface of the screen being wrinkley ,not smooth like most cars.

The screen looks to be the original one ,I'm not sure whether to have it changed, has anyone else got this problem, the car is an 02 Fabia 1.9 TDI Elegance.

Not got the problem but have heard of it. Certainly the replacement screen I had fitted due to a chip is better than the OE one but the OE one wasn't actually bad except for maybe at the very base.

Could be starting to de-laminate, get Autoglass or similar to check it out.
