Boston Gas Permeable lenses

Insist on the highest quality materials for your vision, comfort and eye health

Boston is a recognized name in innovative materials and solutions for gas permeable (GP) contact lenses. We provide exceptional contact lens materials for your eyes, as well as peace of mind—so you know you're getting the best in vision care.

GP lenses are made of rigid plastic materials and can provide crisp vision for a range of irregular cornea shapes

Some GP lenses are smaller in diameter and float on the pupil and some on the iris (the colored part of the eye). Other GP lenses, called scleral lenses, have a larger diameter and float over the entire iris and onto the sclera (the white part of the eye). Your eye care professional will order GP lenses in exact parameters for your prescription.

Whether you're new to contact lenses, looking for contacts with updated features, or just ready to replace your old lenses, make Boston your choice for corneal health and exceptional vision.
