There are two general categories of contact lenses: soft and rigid gas permeable (RGP).
According to the reference provided, these are the two main categories:
- Soft Contact Lenses: These are typically more comfortable initially and are the most commonly prescribed type.
- Rigid Gas Permeable (RGP) Contact Lenses: These lenses offer sharper vision and are more durable than soft lenses.
All contact lenses, regardless of the type, require a valid prescription.
