  2. Bi-weekly (Two-week) Disposable Lenses
    • Lifespan: Up to two weeks
    • Description: These lenses are meant to be worn daily and removed each night for cleaning. After two weeks of use, they should be discarded. Bi-weekly lenses offer a balance between convenience and cost.

    • Lifespan: Up to seven days and nights, or up to 30 days for some brands
    • Description: They are convenient but carry a higher risk of complications like infections and corneal ulcers.
  5. Rigid Gas Permeable (RGP) Lenses
    • Lifespan: Up to one year or more
    • Description: Unlike soft lenses, RGP lenses are made from durable materials that allow oxygen to pass through to the cornea. They provide sharp vision and are often used for complex prescriptions. RGP lenses require proper care and handling but last much longer than soft lenses.
