Close: Commonly it is slightly higer like -4.50 and -5.00 but this depends in part on the goal and how long since your last examination. Also at your age there is the issue of bifocals due to near vision needs. Useful to check with your ophthalmologist for the best information on this.

What would you suggest I do to convert my glasses prescription to contact lens prescription?

Slightly tricky: Mostly straightforward if there is no astigmatism but a little involved if there is astigmatism. I assume you are ordering lenses online and will need that conversion. There is also some experience functions depending upon the type of lens. Check with your ophthalmologist to get this done for you. Optometrists are unlikely to do it as they prefer to sell you lenses.
