Rigid gas permeable contacts do not CORRECT your vision. What they do do, is slow down the deterioration of your vision.
They are uncomfortable compared to soft lenses and can take months to get used to. RGP lenses work by floating on your cornea. Soft lenses sit directly on the cornea. I’ve tried on a pair of RGP’s before and they were awful.
To tell you the truth, I don’t really know any OD’s that prescribe these types of lenses for just any patient. I’ve seen them prescribe them to people who have large changes in their prescriptions every year, to try to slow down the process. Also, people with kerataconus (a thinning and steepening of the cornea) wear these types of lenses. So unless there is an underlying problem, the doctor’s that I’ve worked with only prescribed them for those types of cases. Occasionally, you have the person who’s been wearing RGP’s for 20 years and they don’t want to switch to soft lenses. RGP’s are definitely easier to handle because they are like small hard plastic discs that are about the size of a pencil eraser. They aren’t as fragile so they don’t tear, BUT, they can break. They can also spontaneously pop-out more often. They are specially made for the patient and usually run between $150-$225 for one pair. They are ALWAYS a special order lens. These aren’t the type that they would be able to pull from stock if you lose or break one. With soft contacts there is a “small awareness”…with RGP lenses, you will DEFINITELY feel them in there until you almost wear up a callous under your eyelids from them. Like I said, they take a while to get used to…
Talk to your doctor…he may not feel that RGP’s are right for you…
There are contacts called Ortho-K lenses that work by re-shaping the cornea while you sleep. You wear them at night, and take them out in the morning and it lasts just about all day. Not all Optometrist’s are licensed to fit these and they cost between $800-$1000 for both eyes.

I would not bank on them to correct your vision (not back to zero, or stopping them changing)
There are lenses designed to do this (orthokeratology) but that’s a whole different field.
Statistically, GP lenses do tend to slow the rate of myopic shift, but the effect should not be exaggerated.
They are the second healthiest type of CL, after daily wear soft lenses used correctly (trying to re-use daily lenses wrecks that !)
In general GP lenses offer the sharpest vision and best contrast sensitivity but can suffer from glare at night especially if you have large pupils.
The comfort is usually fine, provided people persist through the acclimatisation period (1week to 1 month)
The exceptions are for very active sports and windy dusty conditions. Arizona is not a place for GP lenses.
I’m not up-to date on current prices.
