Benefits of Extended Wear Contact Lenses

The idea of waking up every morning and seeing perfectly without surgery is an appealing concept, and one that prompts many people to use the extended wear contact lens. These lenses are made generally for weekly use, and some of the new technology has allowed development of 30-day lenses. While years ago the extended wear lens was subject to the usual large barrage of cleaners, enzymes, and conditioners, the extended wear contact lenses of today are thrown away at the end of the wearing period.

The Basic and Essential Benefits of Extended Wear Contact Lenses

Extended wear contacts are designed to be worn overnight. They have up to 6 times more permeability than regular soft lenses, and are divided into two categories: extended wear (lenses worn for around one week), and continuous wear contact lenses (designed for wear up to 30 nights).

How Extended Wear Contact Lenses Work

Although the increased oxygen permeability of silicone hydrogel makes it possible to wear these lenses longer and have good eye health, users still have a higher risk of complications. Ulcers of the cornea are more common among extended wear contact users, although this risk can be reduced by better care and handling. The risk of bacterial infections is higher with both kinds of extended wear contact lenses.

The Convenience of Extended Wear Contact Lenses

Still, most extended wear patients enjoy the convenience these lenses provide and are careful in their handling. Because more oxygen can reach the eye with the extended wear hydrogels, people who wear their contacts for long periods of time find greater comfort with them. Also, those who work different or longer shifts find them more convenient and comfortable as well, as do people who work on computers or do close work with their hands. Often they are comfortable enough that many opt to use them as daily wear lenses and not sleep in them.

Reducing Protein Desposits with Extended Wear Contact Lenses

One of the advantages to using extended wear contact lenses as daily wear contacts is that it reduces protein deposits; this is especially noticeable in the continuous wear, where 30 days of protein will accumulate. Patients with allergies will also want to consider shorter-term wear for extended wear contacts for the same reason, as well as for their general comfort.

Don't Forget the Importance of Proper Contact Lens Hygiene

Remember that hygiene is extremely important with lenses that will stay in your eye for long periods of time. With the proper care, your extended wear and continuous wear contacts can provide you with enormous comfort and clarity.  By making certain that you follow a proper course of contact lens hygiene with your extended wear contact lenses, you will be certain to maintain eye health today and well into the future.
