Hi,
Is there any research out there that shows at what point it makes and actual safety difference for a person to wear glasses?
I recently got a very mild prescription (-.75D and -.5D) and without them on, everything seems normal, but once I put them on, esp. at night I think "wow, things are much crisper now!".
I do feel safer driving with them on, but I was wondering, is there any research out there on the safety improvements of glasses vs. no glasses over various ranges of near-sightedness? Are there prescriptions that are so weak they wouldn't make a difference in terms of driving safety?
