Introduction to Contact Lenses
Contact lenses are thin, curved discs made of plastic or glass that are placed directly on the surface of the eye to correct vision problems. They work by refracting light properly, allowing it to focus on the retina. There are several types of contact lenses available, including soft contact lenses, rigid gas permeable lenses, and hybrid lenses. Each type has its unique characteristics, advantages, and disadvantages.
Types of Contact Lenses
There are two main categories of contact lenses: daily wear and extended wear. Daily wear lenses are designed to be worn during the day and removed at night, while extended wear lenses can be worn continuously for several days. Extended wear lenses are further divided into two subcategories: continuous wear and flexible wear. Continuous wear lenses can be worn for up to 30 days without removal, while flexible wear lenses can be worn for up to 7 days.
Risks Associated with Extended Wear
Wearing contact lenses for extended periods can increase the risk of complications, including eye infections, corneal ulcers, and vision loss.
