Since understanding contact lenses types and wear schedules can seem overwhelming we asked Optician Claudia Rojas to answer some of our top questions. Through eye examinations and contact lens fittings, your Eye Care Professional will be able to assess the contact lens product to prescribe to you.

What are the different types of contact lenses?

The most commonly known lens material types in today’s market are soft lenses and Rigid Gas Permeable (RGP) lenses.

Soft lenses are made from an oxygen permeable material, such as hydrogel, that is both thinner and more flexible than RGP lenses. Most people are prescribed to wear soft lenses as they are more comfortable and easier to adapt to, are more affordable, and can be changed frequently.

RGP lenses may be prescribed if your prescription values and/or corneal surface is better suited to this type of lens. These lenses are made of rigid silicone material that allows more oxygen to pass through the lens than regular disposable contact lenses and are custom fit to the eye.

What types of prescriptions can be corrected by contact lenses?

Spherical Lenses

Lenses designed to correct myopia (nearsightedness) and hyperopia (farsightedness). These are the most common type of contact lenses.

Toric Lenses

Lenses designed to correct astigmatism, which occurs when the cornea (clear tissue covering the front of the eye) is abnormally curved.

Multifocal Lenses

Lenses designed to correct presbyopia by allowing multiple prescriptions in one lens (known as the ADD) so you can see both near and far.

What kind of contact lenses are prescribed by Eye Care Professionals?

Daily Contact Lenses

Daily contact lenses are very simple to wear as they do not require cleaning at the end of the day. Rather, they are disposed of and a new pair is opened from a sealed package the next day.

Bi-Weekly & Monthly Contact Lenses

Bi-weekly and monthly contact lenses are reused for 2 to 4 weeks. Your wear schedule is determined by the product type and under the advisement of your Eye Care Professional.

Rigid Gas Permeable (RGP)

RGP lens replacement schedules range from 1 to 2 years, with the exact modality dependent on your individual needs.
