Rigid Gas Permeable Contact Lenses
Rigid gas permeable lenses offer greater visual acuity, though there are some disadvantages as well.
Specific Gravity of Contact Lenses
Specific gravity is a ration of the density of a substance to the density of water at a specific temperature. Studies show that in contact lenses, this may affect how well the lens holds its position.
Caring for RGP Contact Lenses
RGP contact lenses need to be cleaned carefully to remove deposits. They are stronger than soft lenses so this is easier.
Gas Permeable Lens solutions
Rigid gas permeable lenses must be kept clean as it is vital that they retain their gas permeable qualities.
