Rigid gas permeable lenses (RGP’s) were the only contact lens available when contact lenses first became developed. Soft contact lenses have dominated the market place since then. RGP’s will never go away. They fill a special niche. Patients with irregular corneas, history of trauma, and certain conditions like keratoconus may benefit greatly from RGP's.
Hybrid contact lenses are a more recent product. The hybrid lens is a combination of RGP and soft contact lenses. The center of a hybrid is an RGP button, surrounded by a soft contact lens skirt. This lens type is becoming more popular for patients that need a special lens, but may be unable to wear RGP lenses or scleral lenses.
Myopia is also known as nearsightedness. People with myopia can see better up close (near) than far away. This type of refractive error is becoming more of a public health concern. Extreme myopia can create its own host of problems. Myopia control lenses are designed similar to a multifocal lens. The intent of the lens is slow the rate of myopia until children are old enough to reach adulthood. In adulthood, the axial growth stops.
