I've been wearing 1-day Acuvue for the last five years, but now have to change as my optician tells me they are being withdrawn. I am very short sighted (-12) and have some blood vessels growing into my cornea so need to get more oxygen through.

I've tried a few different Silicon Hydrogel lenses - daily and 2-week wear, but my vision is not clear in them - and they don't make higher prescriptions.

Has anyone else found poor vision with Silicon Hydrogel lenses at high prescriptions?

Any other ideas for alternative lenses?
