I found a cheap Quest 2 on facebook marketplace, but it has a cracked lens. As a person who has some pc building experience, but none in repairing whatsoever, would it be possible for me to repair it/ get it repaired?
It can be done, but Meta does not provide official replacement lenses. My recommendation is to find the lenses secondhand on eBay, or see if you can buff them out with some kind of polish/scratch remover.
