RGPs are smaller in diameter than their counterparts soft.But the differences do not stop there. Due to its composition of partial silicone, PSI contact lenses are resistant, but much more flexible than traditional hard contact lenses in the world, known as eye PMMAs. Historically, silicone also helped RGP contacts allow more oxygen to pass through contact lens itself and in the eye.After all, silicone is known as oxygen permeable, you know. long-term, that little bit extra oxygen amount to eye health better long-term and greater comfort while the lenses are in the eye.
