Are Your Contact Lenses Uncomfortable?

Most people are familiar with the traditional soft lenses which provide clear vision for those with nearsightedness (myopia), farsightedness (hyperopia), or astigmatism. In certain cases, particularly for those with corneal irregularities or astigmatism, Gas Permeable (GP), Rigid Gas Permeable (RGP) or Scleral Lenses are recommended.

Some people experience discomfort when wearing gas permeable lenses, and for those patients, scleral lenses are a much better alternative.

What Are Gas Permeable Contact Lenses?

Modern-day hard contact lenses often provide sharper vision than eyeglasses or soft contact lenses. Gas permeable lenses are made of hard plastic materials and are called ‘permeable’ because they transmit oxygen to the cornea, thus keeping it healthy. GP lenses are ideal for individuals with astigmatism that may have been told that they cannot wear soft contact lenses.

The rigid nature of the lens holds its shape on the eye, which allows for more clear and stable vision correction. Though it takes a little bit of time to get used to wearing GP contacts, the clarity of vision and durability that these lenses provide make it worthwhile. Gas permeable lenses are uniquely fitted to each patient and take about a week to manufacture.

What are Scleral Lenses?

Custom designed scleral lenses help patients with sensitive eyes or corneal irregularities achieve dramatic improvements in visual acuity and comfort. Scleral lenses vault over the cornea and rest on the sclera instead. This creates a new optical surface and prevents discomfort by minimizing irritation to the cornea. Moreover, the reservoir of pure saline solution between the back surface of the lens and the front of the cornea ensures that the eye is always in a liquid environment – making it optimal for health and comfort. This unique design makes scleral lenses the ideal lens for comfort, sharp vision, and healthy eyes.

We recommend scleral lenses for the-hard-to-fit eyes, those with keratoconus, or astigmatism, or for people with a medium-high astigmatism that other contacts can’t comfortably correct. Scleral lenses are also perfect for anyone wanting to wear comfortable lenses while keeping eyes hydrated all day.

Below are the advantages and disadvantages of wearing GP lenses. This information can better assist you in making a better decision with regards to whether to choose one over the other.

What are the Advantages and Disadvantages of Wearing Gas Permeable Lenses?

Advantages of Gas Permeable Contact Lenses

Gas permeable contact lenses have a number of distinct advantages over typical soft contact lenses. In many instances of various eye conditions, a GP contact is required as soft contacts will not be comfortable or deliver the vision correction required. Here are some advantages.

Health & Hygiene

close eye with scleral lenseBecause these lenses are oxygen permeable, they provide the wearer with better comfort and a healthy cornea. Their ability to transmit oxygen reduces eye problems, such as dry eyes, which is caused by diminished oxygen transmission to the cornea – common among most soft lens’ brands or hard (non-GP) lenses.

GP lenses are made from a firm plastic material and retain their shape when you blink. This tends to provide sharper vision than pliable soft lenses and are extremely durable; unlike soft contact lenses, they don’t tear easily. They are easy to clean and disinfect, and when properly cared for, a pair can last a year or more.

Gas permeable lenses are made of materials that do not contain water and thus don’t absorb water from your eyes. Moreover, they harbor fewer protein and lipid deposits from your tear film than other contact lenses do, which renders these lenses a more hygienic and healthier alternative for your eyes.

Comfort…After a Time

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 to get used to initially, ultimately, many wearers may find that, over time, these lenses become comfortable.

Improved Visual Clarity

Due to their rigid material, GP lenses have a smooth surface and maintain their shape, moving along with the eye to hold their place. This provides sharp and stable vision. Furthermore, because they do not dehydrate, they don’t cause reduced vision, which is usually the case with traditional contact lenses. GP lenses can be worn on all eyes, but are particularly fitting for those with astigmatism or bifocal needs.

Cost of Gas Permeable Lenses

GP lenses are durable and long-lasting. Though costs are initially higher than traditional contact lenses, in the long term they are more cost-effective, and unlike disposable lenses, they don’t require ongoing replacement.

So why doesn’t everyone wear gas permeable lenses? Primarily because soft lenses are instantly comfortable, whereas GP lenses require an adaptation period before they reach the same level of comfort.

Disadvantages of Gas Permeable Contact Lenses

Sometimes, whether due to sensitivity, corneal irregularities, or various eye conditions, a gas permeable contact lens isn’t the ideal solution and scleral lenses may be required or preferred.

Requires an adaptation period

To achieve maximum comfort with GP lenses, you need to wear them regularly. If not worn for a week, you’ll require a few days to adapt and get comfortable wearing them again. This distinguishes them from soft contact lenses, which, even if not worn for a long period of time, are comfortable upon insertion.

Unstable on the eye

GP lenses are smaller in size than soft lenses, which means that they are sometimes prone to shifting or popping out. If stability is essential, scleral lenses are a better bet.

Dust and debris

If you’ve tried gas permeable lenses and have experienced any of the above, or if you’re seeking a more comfortable alternative to wear all day, it’s worth looking into scleral lenses.

Visit us to find out how scleral lenses can be a better option for you. At the The Sclerals Center At Coastal Family Eyecare, in Pensacola our eye doctors specialize in fitting custom contact lenses, including sclerals, which provide excellent, effective vision correction for many hard-to-fit eye conditions, such as keratoconus and irregular corneas. We also recommend scleral lenses for astigmatism, when other types of contacts don’t work well.

We fit sclerals for patients from the Pensacola area, as well as Orange Beach,Tallahassee, and Mobile, throughout FL.

What are the Benefits of Wearing Scleral Lenses?

Scleral lenses provide the very best level of comfort, visual acuity, and stability.

Stable Vision

With scleral lenses, you’ll experience consistently clear vision. Their large diameter ensures that they stay centered and stable on your eye. Their size also prevents sclerals from popping out easily, even if you play sports or lead a very active lifestyle.

Long-Lasting Lenses

Constructed from high quality, durable materials, these gas permeable lenses typically last for the long haul. Therefore, while the initial cost of scleral lenses may be higher than standard contacts, you’ll benefit from the maximum value for your money.

Safe and Easy-to-Use

The large size and rigid material make scleral lenses much easier to insert and remove from your eyes. These features also reduce the risk of accidentally injuring your cornea while you handle your lenses.

Comfort for Dry Eyes

While the scleral lenses vault over your cornea, they contain a pocket filled with moisturizing tears. This wet, lubricating cushion offers a very comfortable wearing experience, as well as healthier eyes. In addition, because sclerals don’t touch your corneal surface, rubbing is minimized and your risk of corneal abrasions is drastically diminished.

Wide Visual Field

The wide optic zone provides wearers with a wider, more precise peripheral vision. They also reduce sensitivity to glare and light.

Cost-effective

Scleral lenses are custom-fit to each eye. Though the fees for fitting sclerals and the cost of the lenses are higher than standard lenses, their life span and benefits make the cost worthwhile.

Though coverage rates and restrictions vary among providers, if considered a medical necessary, most insurance companies will reimburse the cost of scleral lenses. Consult with our eye care team at the The Sclerals Center At Coastal Family Eyecare to discuss your specific payment options and cost of scleral lenses.

Are Scleral Lenses Better Than Gas Permeable Lenses?

In terms of comfort, visual clarity, and stability, scleral lenses are superior to gas permeable lenses. In cases of corneal irregularity or severe sensitivity, scleral lenses are often the only viable option. However, they are more costly than GP lenses as well.

The question of which contact lens is best for you should ultimately be decided in conversation with us. Trained in fitting specialty contact lenses of various types, from the simple near-sighted first-time wearer to the complex astigmatic, bifocal or diseased cornea patient, Dr. Leonard will consult with you about your best options.
