Are contact lens prescriptions generally a half point higher than ones for glasses?

[eflat]

I used to wear contacts but then went back to glasses but now want to go get contacts.

My vision has not changed for years but for some reason the contacts I had were the same as my eyeglass prescription (-4.75) but I could not see right at all.

Contact perscriptions are usually higher (or lower, I cant remember) becasue the optics are much closer to your eye.

Usually by a whole point.

I cant speak for someone who may be farsighted, but I am quite nearsighted, and my glasses perscription is one point higher than my contacts

[edit] I no can speel.. sigh [/edit]

Mine are the same (-2 left eye, -1.75 right eye).

I'm nearsighted with a -0.75 to -1.00 astigmatism. My contacts are 0.25 lower than my prescription. It's lower cause the lense is closer to your eye, so less correction is needed; just push your glasses closer to your face and you should see the effect.

I do have an astigmatism though. As a result, my optometrist initially made my contacts 0.50 higher to 'compensate' in hopes of saving some money. NEVER do this. I wore these for a few days and my vision was unacceptably blurry. After getting toric lenses, I have been very happy.

When I had contacts, I remember both of mine being +/-.5 of my glasses prescription. Not sure which one + or -. I'm up to 5.75 and 5.25 with glasses I'm fucking blind.

More than likely you were having astigatism corrected with the glasses and not the contacts, or corrected to a better level than available in contacts.

give me a break I'm close to 5 and my dad has -8 in one eye (well, before surgery now both eyes are still good 6 + years later.) And I have a pal with -11. He's blind.

I'm nearsighted and my contact prescription is about .5 lower than glasses. -5.00 for contact and -5.50 for glasses

The answer is vertex distance. Google it...
