Hello my brother was born with congenital cataracts (Removed without IOL) and is looking to replace his current progressive aphakic glasses. they are apsheric essilor varilux digital lenses 1.74 index. he is blind in one eye and as such has a balance lens in the bad eye. These glasses work well but is there anything else out there that can further reduce the distortion and lens thickness. I heard there may be double aspheric lenses? any tips would be greatly appreciated.
