Many people wear contact lenses for different reasons. Some wear them for fashion and most wear because of the health condition of their eyes. They are popularly used as substitute to regular eyeglasses.
What are contact lenses? They are small plastic visual devices with a curve shape that will follow the shape of the wearer’s eyes. They are used to correct vision problems (myopia and hypermetropia). They are corrective measures for the eyes and also, for therapeutic and cosmetic reasons.
There are types of contact lenses: the soft and the gas permeable (RPG) or rigid contact lenses. But the question as to which type is good for you, the choice depends on your eye care practitioner. Soft types are made of hydrophilic plastics that absorb liquid and must be kept moist for softness. This kind is extremely comfortable and gives easier molding to the corneal surface. It is commonly used over the other. Rigid lenses are composed of durable and flexible plastics. It allows oxygen to pass through to the cornea. It is also easier to maintain. Another type is the corrective versus the cosmetic contact glasses. Corrective type enhances eye vision while cosmetic type is used for fashion or functional perks. Daily and extended wear contact lenses are another pair of the different types. Daily type is used only during day time while extended type can be worn overnight up to six or more successive nights. The last pair is the toric and the spherical contact lenses. In spherical type, the power correction focuses on all meridians while in toric contact lenses, the power correction is different meridians.
