Gas Permeable Lenses

Gas Permeable Contact Lenses are today’s most state-of-the-art “hard” contact lenses.

Hard lenses were made of a material known as PMMA, and before 1971, when soft lenses were introduced, just about all contact lenses were PMMA. PMMA lenses were difficult to get used to, and uncomfortable to wear. They also did not allow oxygen to pass through them and hence caused long term complications.

What makes GP Lenses different?

Introduced in the mid 1980s, they are actually a newer technology than soft lenses. They incorporate silicone, which makes them more flexible then PMMA whilst also being more oxygen permeable. This results in greater comfort and better eye health.

Gas permeable lenses can also provide better vision, more durability, and increased deposit resistance than soft lenses. They are also easier to clean, are longer lasting and less expensive in the long term than soft lenses.
