Contact Lenses

Listed are some of the contact lens options to consider:

Soft contact lenses

These lenses are made of soft, flexible plastics that allow oxygen to pass through to the cornea. Soft contact lenses may be easier to adjust to and are may be more comfortable than rigid gas permeable lenses. Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses.

Rigid gas permeable contact lenses (RGPs)

RGPs are durable and resistant to deposit buildup. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses. They are easier to handle and less likely to tear. It may take a few weeks to get used to wearing RGPs, compared to several days for soft contacts.

Extended wear contact lenses

Extended-wear contacts are available for overnight or continuous wear ranging from one to six nights or up to 30 days. They are made of flexible plastics that allow oxygen to pass through to the cornea. There are also a very few rigid gas permeable lenses that are designed and approved for overnight wear. Length of continuous wear depends on lens type and your tolerance for overnight wear. It’s important for your eyes to have a rest without lenses for at least one night following each scheduled removal.

Disposable (replacement schedule) contact

Disposable contacts offer both comfort and convenience for most contact lens wearers. Disposable contacts are usually available as follows:

    • Daily disposables― Single- use (daily disposable) lenses are designed to be replaced every day. They are typically best for patients with eye allergies or other conditions, because they limit the deposit and build up of antigens and protein. Single use lenses are also useful for people who use contacts infrequently, or for purposes (e.g. swimming or other sporting activities) where losing a lens is likely.
    • Two-week replacement disposablesThese lenses can be worn daily for two weeks (taking them out every night and putting them in every day). The main advantage of wearing disposable lenses is that you put a fresh pair of lenses in your eyes every two weeks, limiting protein and antigen build up. Another advantage is ease of care with multipurpose solutions.
    • One-month replacement disposablesThese lenses are similar to two-week replacement lenses but are thrown out every 30 days.

Bifocal or Multifocal contact lenses

The lenses are designed to provide good vision to people who have a condition called presbyopia. A sign that you are developing presbyopia is that you need to hold menus and other reading materials further from your eyes to see it clearly. These types of contact lenses are available in soft disposable or rigid gas permeable designs.

Toric lenses

Toric lenses are designed for people with astigmatism. They have two powers in them, created with curvatures at different angles (one for astigmatism, the other for either myopia (near sightedness) or hyperopia (far sightedness). There’s also a mechanism to keep the contact lens relatively stable on the eye when you blink or look around.

Properly fitting a toric lens takes time and requires more expertise than regular contacts. Consequently you can expect that a fitting for torics will be more expensive than a regular contact lens fitting. The lenses themselves also cost more than spherical lenses.
