It is not possible to tell from a glasses RX what the vision is. Just like looking at a pair of shoes you can't tell how tall the person is.
Assuming you have a eye free of disease your distance vision without glasses is likely 20/200 or worse. Your near vision without glasses is likely 20/20.
Since this important call your "eye doctor" and find out. If you need to see better for a career in rescue then see an eye MD ophthalmologist and discuss refractive lasik surgery. Find one near you at www.aao.org

if my prescription is -3.25 and -3.50, what would my visual acuity be? need to know this before applying for a job in the rescue sector!

I generally do not do glasses tests in an infected eye. Better repeat after the infection has cleared.

I'm a 42 year-old generally healthy woman residing in Europe, with bilateral moderate nearsightedness (-5.5 and -5). I happened to see my doctor at the time when I was just suffering from an eye irritation with increased lacrimation. She diagnosed an eye infection and prescribed local antibiotic drops. At the same time she gave me a visual acuity test (for which I had scheduled the appointment in the first place so as to order a new pair of glasses) and the result was a very disappointing: -6.5 (aggravated) myopia. I was wondering if I can rely on this result, or better have the Snellen test repeated in a week or two when the infection will have subsided? Is it OK to give a prescription for new glasses at the time of conjunctivitis anyway? Thank you, C.Teszler
I would not put much stock in your "finding" on the web. I doubt if it has any basis in fact. Plus a patient with normal eyes and a RX of -2.00 will see 20/20 at 18 inches and the visual acuity will continue to change out to 20 feet.
