Our contact lens specialists at Zacks London Eye Clinic (Warren Street, Fitzrovia, London W1) fit hard, rigid gas permeable contact lenses also known as GP or RGP contact lenses from several different suppliers so that we can prescribe the most appropriate visual solution for your eyes and lifestyle. Hard, RGP contact lenses are tailor made from rigid plastic materials which are now generally called gas-permeable (GP) due to their oxygen permeability.
Hard contact lenses offer health benefits over soft contact lenses: They don’t dehydrate, are less likely to harbour bacteria and they allow more oxygen to pass to the eye by floating on the tear layer.
Since they retain their shape, rigid gas permeable contact lenses usually provide sharper vision than soft contact lenses. Though because of their rigid structure, gas permeable contact lenses do require some adaptation, becoming more comfortable over time with regular wear.
‘Very thorough exam and superbly fitted lenses… the aftercare and support were exceptional’
