Topic: Contact Lenses
MDLinx.com reported: "Scleral and corneal rigid lenses represented 100 per cent of the contact lens market immediately prior to the invention of soft lenses in the mid–1960s. In the United Kingdom today, rigid lenses comprise 2 per cent of all new lens fits. Low rates of rigid lens fitting are also apparent in 27 other countries which have recently been surveyed. Thus, the 1998 prediction of the author that rigid lenses –also referred to as 'rigid gas permeable' (RGP) lenses or 'gas permeable' lenses–would be obsolete by the year 2010 has essentially turned out to be correct."
