Is it necessary to wear glasses if you have distant visual acuity?

No: If you see well at distance without glasses or contacts, that is fine. Not wearing glasses, even if needed, does not hurt or damage your eyes, if you are over 45, you may need reading glasses if you have good distance vision . Or, you can try monovision with a contact lens, with the non-dominant eye set for reading. Lasik in the non-dominant eye for reading might also be an alternative to explore.

Didtant vision.: If you have a distant vision problem and it is due solely to a refractive error, then glasses or contacts or refractive surgery will correct it. If it is due to a non-refractive problem then it will require other treatment.
