Optometry and contact lens
Introduction
Contact lenses enhances the vision of the the wearer by reducing spectacle aberrations and increasing the visual field, thus giving a natural vision
Soft contact lenses
Standard Contact lenses : These lenses are available as spherical lenses and toric lenses which can be used everyday for about 8 hours and should be replaced every year.
Disposable contact lenses : These latest generation lenses are available as spherical and toric contact lenses which can be disposed as either quarterly, monthly, fortnightly, weekly or on a daily basis.
Cosmetic contact lenses : As the name suggests, these lenses are worn to enhance cosmetic appearance by changing the eye color.
Bifocal contact lenses : These lenses correct presbyopia by correcting both distance vision and near vision by a single pair of contact lenses.
Semi soft contact lenses When a person is intolerent to soft contact lenses due to allergy or under correction of high astigmatism, he will be adviced to wear semi soft contact lenses.
Special Contact Lenses
Keratoconus Lenses:
Keratoconus is a progressive disease that involves the thinning and steepening or “bulging” of some, but not all, of the cornea. The area affected is usually at or near the center of the cornea. In keratoconus, the cornea becomes very irregular in shape and increases in astigmatism. Because of the cornea’s unusual shape, eyeglasses and soft contact lenses can’t fully correct vision to an acceptable level.
In keratoconus for good vision we need alternative in form of special contact lenses like- YK contact lenses, scleral contact lenses,corneal GP lenses, piggyback lenses,hybrid keratoconus lenses etc. At SECC we provide you these lenses after careful examination.
