How to troubleshoot blurred headlights in my Audi 80?

I have noticed that the headlights on my Audi 80 have become increasingly blurred and foggy. I have tried cleaning them but it doesn't seem to make a difference. Is there a way to fix this issue?

Have you tried using a headlight restoration kit to remove the haze and restore clarity to your headlights? This could be a cost-effective solution to your problem. If that doesn't work, you may need to replace the headlights altogether.
