Gas Permeable (GP) Contact Lenses

Gas Permeable (GP) or Rigid Gas Permeable (RGP) contact lenses are an alternative to soft contact lenses that are made from a hard, oxygen permeable material.  GP lenses are currently less popular than soft lenses but offer a number of advantages and are continuing to improve as research and technology advance.

GP contacts are made of a firm plastic material which allows the passage of oxygen through the lens to your cornea and the front surface of your eye - essentially allowing your eye to “breathe”. This increases comfort, health and safety during contact lens wear.

Benefits of GP or RGP Contact Lenses

Because of the strong material and the ability to diffuse oxygen, GP lenses offer a number of advantages over soft contact lenses.

Health and Hygiene Benefits:

Unlike soft lenses, GPs don’t contain water which makes them less likely to attract and breed bacteria that can cause eye infections. Further protein deposits won’t build up on the lens, keeping them cleaner and healthier.

Because they are made with a strong durable material, GP lenses won’t tear and are easy to clean and disinfect.  RGPs maintain their firm shape and will not dehydrate.  Further GPs last longer than soft lenses - when cared for properly, a pair can last a year or more.

Comfort

GP contact lenses are custom made for each patient based on the eye’s individual curvature, size, corneal shape. Their ability to transmit oxygen reduces eye problems such as dry eyes caused by reduced oxygen that are common in many brands of soft lenses or hard (non-GP) lenses.

GP lenses have a smaller diameter than soft contacts, meaning that they cover less of the surface of your eye. While this may take some time getting used to initially, ultimately many find that they are just as if not more comfortable than soft contacts.

Better Vision

Due to the rigid material, GPs have a smooth surface and maintain their shape, moving along with the eye to hold their place.  This provides sharp and stable vision. Further they do not dehydrate, which is often a cause for reduced vision with other lenses.

Cost

Because they last so long, GPs are much more cost effective than soft lenses, especially disposable lenses that require a constant supply. Because they are made to order, there is an initial cost investment and they will take up to a week to manufacture if you do need a replacement pair.

GPs for Astigmatism

GP lenses are ideal for individuals with astigmatism that may have been told that they cannot wear soft contacts. Because of the rigid nature of the lens, they hold their shape on the eye allowing for more clear and stable vision correction.

Adapting to GP lenses

One of the downsides of GP contact lenses is that they require an adaptation period, particularly if you are used to soft lenses with a larger diameter.  One of the major differences is an experience of “lens awareness” in which you feel the edge of the lens when you blink. It could take up to a few weeks to get used to the lenses but many people report that after this initial period they find that GP lenses are just as if not more comfortable than soft lens varieties.

GP Lenses for Myopia Control and Ortho-K

Research shows that gas permeable lenses might be effective in slowing the progression or worsening of myopia or nearsightedness, particularly in children. They are also used in Orthokeratology (ortho-k), a vision correcting procedure in which you wear the lenses at night to reshape your cornea for improved vision during the day.

We are pleased to announce that all three of our Vision Source locations will be reopening for service during the week of May 4th, 2020.

During this difficult time, we have made adjustments to our services to ensure the health and safety of your patients, our staff, and our Doctors.

For the Protection of Our Patients, we have implemented the following procedures in our clinics:

Limited Appointment Scheduling - in order to ensure we are able to properly disinfect and adhere to Social Distancing Guidelines set forth by our local authority.  Certainly, urgent and emergency patients will be prioritized.

Fever Free Environment - Temperatures will be taken upon entering the clinic of all patients, staff, and doctors.  Anyone with 99.5 degrees or higher will be asked to reschedule.  Anyone who is taking a fever-reducing medication such as ibuprofen or acetaminophen will be asked to reschedule once the medication is clear from their system so we can be sure of an accurate temperature reading.

Pre-Screening Questionnaire - We will continue to ask any patient with URI symptoms to reschedule their appointment until they have been asymptomatic for 3 days or have a negative COVID test.

Face Covering - We are requiring everyone entering our clinics to wear some type of facial covering such as a homemade mask, scarf, bandana, or handkerchief.

Wash hands and sanitize - Upon entering the office, everyone will be asked to sanitize their hands.  Additionally, we will request they sanitize their hands before re-entering the business area.

All Vision Source staff with direct patient contact will be required to wear a mask.

Social Distancing - We are limiting the number of patients in our office and are asking, when possible, only the patient enters our clinics for their visit.  Please ask the person with your patient to stay in their car.  We can text them if they need their assistance.

When scheduling patients, we will be:

  1. Asking them if they have been diagnosed with COVID or been in contact with someone who has been diagnosed with COVID.  In those cases, we will postpone seeing the patient unless emergent.
  2. We will ask if they have any current symptoms of COVID.
  3. They will be notified that upon arrival to our office they will have their temperature taken.
  4. We will ask the patients NOT to bring family members with them into the office and we ask patients to wait in the car until they are called inside for their appointment.
  5. We will ask the patient to bring their own mask or face covering.  All of our doctors and any staff who will have direct patient contact will be masked.

Thank you for your support and understanding during these unprecedented times.

Please stay safe and healthy.
