Is there a way (even if it's very rough) to know the amount of blur someone !
Question: Is there a way to know, say, how much blur someone with a -2.50 rx is experiencing (even if it's not accurate at all or very very rough)?
Is that the sort of prescription that should be worn "just for some occasions" or more of a should be worn full-time rx?
ps.I'm just curious about my sister's rx, mine is higher and I do wear contacts full time.

You can try on +2.50 ready made readers from the drug store or dollar store on top of your contacts. The resulting vision is how a -2.50 myope sees without glasses.
That is a pretty big correction, mine is three and I think I'm blind as a bat. She should probably wear the lens, especially when driveing.
Ball park that is like a 20/250 Rx. Which means that that person can only see (uncorrected) something that is 250 ft away from 20 ft away. I would highly recommend that you wear your glasses full time. (Dont want to meet you coming cown the road without them, lol)
