RGPs effectiveness

I’ve been using RGPs for a month now but my eyes have become extremely sensitive to light and they’re droopy all the time. Vision has improved but i still have problems with reading, i still have to strain my eyes in order to focus at the letters. My optometrist has told me that it’ll get better when i get used to wearing lenses but i haven’t seen any progress in a month. And the optometrist also said that before going for sclerals the reason should be that RGPs can’t work for me while i don’t have that severe KC that RGPs can’t be enough (for health insurance to pay).
