Disposable Lenses versus Extended Wear Lenses

Contact Lens or simply contacts are medical devices that are worn for accurate vision and are placed directly on the surface of the eye. The increased use of contacts over the years suggests that these are equally beneficial and many people prefer it more than the traditional spectacles. Contacts are known to provide better peripheral vision and they don’t collect moisture or sweat, which makes them ideal for sports and other activities. The two common types of contact lenses are disposable and extended wear.

Disposable Lenses

Disposable or daily wear contacts are made of soft, flexible plastic that permits oxygen to pass through the eyes. These are designed to be worn for a specific period of time and they are replaced with fresh lenses. As these contacts require no cleaning, these have become the most common type of contact lens available. There are also health and convenience benefits associated with it, which is why many ophthalmologists and eye experts suggest it. As these lenses are worn for a specific period of time, this greatly minimises the chance of deadly pathogen build up on the lens surface.

Extended Wear Lenses

As the name suggests, extended wear contact lenses are designed to be worn continuously and even up to seven days without any cleaning or removal. These are made with a special material called silicone hydrogel lens, which allow for better oxygen permeability to the cornea through the lenses than their disposable counterparts. Some extended wear lenses can even be worn for up to thirty days straight.
