Soft Contact lenses

Soft contact lenses are made of soft flexible silicone hydrogel material that allows oxygen to pass through to the cornea. This lens material is easier to adjust to and provides better initial comfort than hard contact lenses. Soft contact lenses are the most common lens material worn.

The majority of soft contact lens wearers must replace their contact lenses according to a particular schedule.

Daily Disposable

Daily wear contact lenses are intended to use during the day. They are not designed for overnight wear. Once it is used, then it must be thrown away. A brand new pair of lenses is used each day. Sleeping in daily wear contact lenses can increase the chances of getting a serious eye infection. Wearing daily disposable contact lenses for more than one day may cause eye discomfort, dry eye, redness, or irritation.

Extended Wear

Extended wear contact lenses are available in two weeks or monthly modality. These contact lenses must be removed every night and can be re-worn for the period of either two weeks or one month.

Wearing contact lenses longer than recommended replacement schedule can lead to possible corneal ulcers, eye infections, and overall discomfort.

Overnight Contact Lenses

There is one lens on the market for overnight wear ranging from one to six nights or up to 30 days. Overnight contact lenses are usually made of material that allow more oxygen to pass through to the cornea while sleeping at night. It’s important for the eyes to rest without contact lenses for at least one night.
