There are two main categories of contact lenses: hard and soft lenses. They each have different benefits and down sides. In this article we will compare hard and soft lenses to help you understand the difference between them.

The two categories of contact lenses

Hard lenses are made out of silicone polymers which facilitate the flow of oxygen to your eyes. This material is rigid which enhances the durability of hard lenses. It also means that they are likely to keep their shape.

Soft contact lenses are made of a plastic polymer that can combine with water. The water in soft lenses enables oxygen to pass through the lens to the eye. This increases comfort for the wearer.
