Individuals who find regular contact lenses uncomfortable may switch to alternative lenses as there are lenses to suit many different visual needs. The various lenses are different in function and appearance. Before getting contact lenses, you should understand the different types available.
Specialty contact lenses address issues that conventional contact lenses cannot solve. Conventional contact lenses sit directly on the eye surface. They cover the cornea and fit correctly to ensure comfort. People with irregularly-shaped corneas find most contacts uncomfortable to wear.
These make it possible for patients with special requirements to enjoy good vision without wearing eyeglasses.
Specialty lenses are available as rigid gas permeable, soft, hybrid, or scleral lenses. Fitting for specialty lenses takes longer and requires more expertise than regular lenses. The specialist examines the patient’s eyes to determine the best lenses.
Patients who suffer from dry eyes can benefit from gas-permeable lenses. The RGPs allow oxygen to reach the cornea, which prevents quick drying of the eyes. The lenses keep the eyes comfortable, and the rigidity helps corneas maintain their shape. They are more resistant to the buildup of deposits, giving clearer vision than regular contacts. They are more durable and easier to handle than soft contacts.
Scleral lenses have a larger diameter than regular contacts, which means they do not sit directly on the cornea surface. They vault over the sensitive surface, creating a space between the cornea and the lens. They are ideal for individuals with corneal abnormalities such as keratoconus and surgical scarring. The space acts as a fluid reservoir that allows the eye to remain lubricated, reducing dry eye symptoms.
Orthokeratology lenses are special RGP contacts that help change the cornea curvature while the patient sleeps. The lenses are removed upon waking, and the individual can enjoy clear sight throughout the day. They improve the ability of the eyes to focus better on objects without wearing glasses. The lenses are mainly used for myopia control.
Soft contact lenses are soft, flexible materials that allow oxygen to reach the cornea. Soft lenses are more comfortable and are easier to adjust to than rigid gas-permeable lenses. New lenses, such as those made from silicone-hydrogel, help provide more oxygen to the eyes while wearing the lenses.
Unlike extended-wear lenses, disposable contacts are for daily wear. The frequent replacement schedule means that new lenses are worn each day. The single-use lenses are convenient for those who do not want to go through the daily cleaning and disinfecting process.
Contact lenses are beneficial for reasons such as practicality and appearance. People who do not wish to wear eyeglasses can get contacts. Other specialty contact lenses include cosmetic contacts that help hide certain eye injuries or disfigurements. They also help change the color of the eyes.
