There already is Reparo, which is used to repair everything. Why is there a specific version for just glasses? And even then, Oculus means eye, not glasses, so it could just fix Harry's near-sightedness immediately. There are spells that can fix up the human body (see Lockards Brackium Emendo to fix Harry's broken arm or Vulnera Sanentur, although that's more of a counter-curse)
