What does "RGP" stand for?

The term "RGP" stands for Rigid Gas Permeable lenses. These are a type of contact lens made from a firm, durable material that allows oxygen to pass through the lens to the cornea. This feature is significant because it helps maintain eye health and comfort by ensuring that the cornea receives adequate oxygen, which is vital for cell function and overall eye health.

Rigid Gas Permeable lenses provide several advantages, including excellent vision correction for a wide range of refractive errors, and they tend to have a longer lifespan than soft contact lenses. They are also less likely to harbor allergens and deposits compared to soft lenses.

The other options, while creative, do not accurately represent the terminology used in the field of optometry or contact lens fitting. Knowing the correct terminology, such as RGP, is crucial for professionals in understanding and communicating effectively about various types of lenses and their characteristics.
