Contact Lenses, Conshohocken PA
A contact lens is a corrective lens placed on the cornea of the eye to improve vision problems such as farsightedness, nearsightedness, astigmatism and presbyopia. An estimated 125 million people use contact lenses worldwide.
Types of Lenses:
There are many different types and brands of contact lenses. Dr. Fracht can help you determine which type of contact lens is right for you.
Soft Contact Lenses: The most common option for contact lens patients is soft contact lenses. These lenses are made of hydrophilic or water-loving polymer. The oxygen-permeable soft lenses allow for comfortable extended periods of wear. Their comfortability combined with their ability to provide clear, stable vision makes soft contact lenses the popular choice. However, soft contact lens do not correct all vision problems, the vision obtained from them is not as sharp as with other lenses, and they tend to soil easily, and therefore need to be replaced more often.
Rigid Gas Permeable Contact Lenses: Another option is the rigid gas permeable (RGP) contact lens. These contacts are made from rigid waterless polymer, and are oxygen permeable. RGPs transmit more oxygen to the eye than soft contact lenses, and therefore promote good ocular health. RGPs are generally prescribed to patients with irregular ocular surfaces, astigmatism not corrected by soft lenses, and to those patients who require a multifocal or bifocal lenses. They are longer lasting, easier to clean, and usually provided better vision than soft lenses. However, RGPs tend to slip off the center of the eye more easily, tend to collect debris under them more than soft lenses, and must be worn consistently at length to promote adaptation.
- Unlike glasses, which tend to interfere with sports and exercise, contact lenses do not. This allows you more freedom to engage in any activity you want without worrying about your vision.
- Contact lenses generally offer better improved sight than glasses.
- For patients concerned with physical appearance, contact lenses offer an invisible option for improving vision.
- One of the main disadvantages of choosing contacts is that unlike glasses, contacts require consistent care. Each night, contacts must be removed from the eye, cleaned in approved solution, and placed in their airtight container. The container must be replaced every month and kept dry when not in use. Failure to adhere to proper cleaning procedures could lead to infection.
- The risk of infection is another disadvantage of contact lens use. Excessive wear of the lenses, particularly overnight wear, is associated with many safety concerns, and could lead to infections in the eyelid, conjunctiva, and cornea. Bacterial infection resulting from improper cleaning of lenses should also be a considered risk.
