At Today’s Vision Pearland, we will perform a contact lens fitting to help you determine the right contact lens for your lifestyle. We have on-site or access to contact lenses from the nation’s top manufacturers (Vistakon – Acuvue, Oasys; ALCON – Air Optix; Coopervision – Bifonity, Proclear, Avaira, and Bausch & Lomb – Purevision, Softlens – to name a few). Depending on the lens, these can be for daily, two-week or monthly use.
Contact lenses are available for a myriad of eye concerns – dry eyes, astigmatism, difficulty reading and eye diseases like kerataconus. The major types of contact lenses include: soft; rigid gas permeable (RGP); extended wear; hybrid; disposable and decorative.
One of the most recent advances in contact lenses is silicone hydrogel that allow more oxygen to pass through the lens to the cornea than regular soft lenses. Silicone hydrogel contact lenses are the most popular type worn in the United States.
Prior to silicone hydrogel contacts, a condition called hypoxia occurred frequently, causing red eyes, corneal swelling, blurred vision and eye discomfort. Although silicone hydrogel lenses allow more oxygen to reach the surface of the eye, the added silicone can reduce the surface wettability of the lenses making it harder for them to stay moist on the eye. To combat this, new contact lens solutions have been developed that include special wetting agents.
According to ALCON Vision, nearly one in five contact lens wearers sleep in their lenses, and nearly two in three are wearing lenses that are not approved for overnight wear. To avoid problems, patient compliance in following the doctor’s instructions is critical. Disposable daily contact lenses can also help.
