Need contact lenses? For individuals with vision problems, contact lenses remain an effective, nearly invisible tool. The ultra-thin plastic contact lenslenses fit over the clear, front part of the eyes to correct vision problems including astigmatism, farsightedness, and nearsightedness. Talk to your eye doctor about the best type of contacts for you. Linsey EyeCare in Wyomissing, PA, offers a full range of eye care services to their patients. Read on to learn about the different types of contact lenses that are available.

Soft Contact Lenses. Soft contacts are the most common lens material worn. Soft contacts are made of a soft, flexible plastic material that allow oxygen to pass through the lens to the cornea—the clear, domeshaped surface that covers the front of the eye. While soft contacts are commonly throwaways, there are some soft lenses that aren't. Soft contacts provide better initial comfort than hard contacts. As a bonus, many soft contacts provide UV protection.

Hard Contact Lenses. Hard contacts are rigid gas permeable lenses, which allows more oxygen to pass through the lens to the cornea. They offer crisp, clear vision and can correct most astigmatism. Rigid gas permeable lenses have been known to help slow down the development of nearsightedness in young adult and adult contact lens wearers. Additionally, these contacts are extremely durable and easy to care for.

Disposable Contacts. Disposable contacts are soft lenses designed to be discarded on a daily, weekly, bi-weekly, or monthly basis. With regular replacement, long-term protein deposits, which can affect vision, the health of the eyes, and comfort, do not build up. Disposable contacts are convenient and require less maintenance than soft lenses. It's important that disposable contact lenses be replaced at their designated time to avoid infection.

Extended Wear Contacts. Extended wear contacts are soft or gas permeable lenses, which are worn for up to 30 consecutive days. While extended wear contacts offer the convenience of not having to take them out at night, sleeping in contacts increases the risk of developing corneal ulcers, infections, and abnormal blood vessel growth in the cornea. Therefore, frequent follow-up visits are necessary. Some physicians will not recommend extended wear contacts.
