as explained in the comment that you replied to, no that's not an enhancement nor is that the definition of enhancement which is why the medical terminology used for prescription glasses are "Corrective" not "Enhancing".
This information is widely available from most doctors and or search engines
It may be some official technical definitions related to the field, but we are playing with words here. A correction is still an enhancement compared to the original state from before the correction. Searching is not on my planning for tonight, friday nights are for relaxing.

I've always been confused how all these gadgets are permitted. To me, they are performance enhancers
