Scleral contact lenses have been making waves in the world of vision correction for the past few years. These lenses have become increasingly popular because they help individuals with a wide range of vision problems to see clearly without any discomfort. However, despite their growing popularity, some people are still skeptical about whether or not scleral contact lenses are completely safe.
From my personal experience, I can say that scleral contact lenses are incredibly safe and effective. I’ve been wearing them for months with absolutely no issues whatsoever. They are designed to sit on the sclera, which is the white part of your eye, unlike traditional contact lenses that sit on the cornea. This design allows for more oxygen to reach your eye, which ultimately prevents any damage to the cornea.
It’s important to note that not all scleral contact lenses are created equal. Some are made of higher quality materials, and others are designed differently to meet the specific needs of different individuals. This is why it’s crucial to consult with a professional eye doctor to determine whether or not scleral contact lenses are safe and suitable for your needs.
What are scleral contact lenses?
Scleral contact lenses are a type of specialty contact lens that are larger than traditional contact lenses and fit onto the sclera, the white part of the eye, rather than just on the cornea. They are made of gas-permeable materials, allowing oxygen to reach the cornea while they are being worn.
Scleral contact lenses are typically prescribed for patients with irregular corneal surfaces, including those with keratoconus, corneal ectasia, and other corneal disorders. They provide a smooth surface for light to enter the eye, improving vision and reducing glare.
These lenses were originally developed in the early 20th century and have undergone significant improvements in recent years. They are custom-fitted to each patient’s individual eye and require a specialized fitting process by an eye care professional.
Pros and Cons of Scleral Contact Lenses
Scleral contact lenses are gaining popularity in recent years due to their unique design and ability to correct a wide range of vision problems, including astigmatism and irregular corneas. However, like all contact lenses, there are pros and cons that need to be considered before making a decision to use them.
- Pros:
- Comfort: Scleral lenses are larger in diameter as compared to regular contact lenses, which means that they do not touch the cornea directly and rest on the white part of the eye, known as the sclera. This reduces irritation and provides increased comfort for users.
- Improved Vision: Scleral lenses are known for their ability to improve vision, especially in individuals with irregular corneas or severe astigmatism. Due to their unique design and ability to re-shape the cornea, scleral lenses provide better clarity of vision.
- Longer Wear Time: Scleral lenses can be worn for longer durations than normal soft lenses, as they are made of rigid gas permeable (RGP) materials that allow for better oxygen flow. Some patients can wear scleral lenses for up to 18 hours without experiencing discomfort or dryness.
- Cons:
- Cost: Scleral lenses are more expensive than regular soft contact lenses and can cost anywhere from 2 to 3 times more. This is due to the specialized manufacturing process required to create the unique shape and size of the lenses.
- Difficulty in Fitting: Scleral lenses require a specialized fitting process, which is more time-consuming and requires more expertise than a typical contact lens fitting. This is because the lenses need to be custom-made to fit the unique shape of each eye in order to provide stable vision and comfort.
- Maintenance: Proper maintenance of scleral lenses is essential to prevent the risk of infection. This involves daily cleaning and disinfecting of the lenses, which can be time-consuming and inconvenient for some users.
In conclusion, scleral contact lenses provide a number of benefits to those with certain vision problems. However, they are not suitable for everyone, and it is important to discuss all options with your eye care professional to determine if scleral lenses are the right fit for you.
If you do decide to go ahead with scleral contact lenses, it is important to be aware of the pros and cons associated with their use. By taking this into consideration, you can make an informed decision about whether or not they are the right choice for your vision needs.

Comparing scleral contact lenses to other types of contact lenses
When it comes to contact lenses, there are several different types that are available. Each type has its own advantages and disadvantages, making it important to consider your individual needs and preferences when choosing the best option for you. In this article, we will be focusing on scleral contact lenses and comparing them to other types of contact lenses.
- Soft Contact Lenses: Soft contact lenses are the most popular type of contact lens. They are made from a soft, flexible plastic that allows oxygen to pass through to the cornea. Soft contact lenses are comfortable to wear and come in a variety of types, including daily wear, extended wear, and disposable contacts. However, they are not always ideal for people with certain eye conditions, such as severe dry eye or irregularly shaped corneas.
- Rigid Gas Permeable (RGP) Contact Lenses: RGP contact lenses are made from a rigid plastic that allows oxygen to pass through to the cornea. They provide sharper vision than soft contact lenses and are typically prescribed for people with astigmatism or other irregularities in the shape of their eyes. However, they can take some time to get used to and may not be as comfortable as soft contact lenses.
- Hybrid Contact Lenses: Hybrid contact lenses combine the comfort of soft contact lenses with the clarity of RGP contact lenses. They have a soft outer layer and a rigid center that provides clear vision. Hybrid contact lenses are often prescribed for people with astigmatism or other irregularities in the shape of their eyes. However, they can be expensive and may not be covered by insurance.
Now, let’s take a closer look at scleral contact lenses.
Scleral contact lenses are similar to RGP contact lenses in that they are made from a rigid plastic material. However, they are much larger in diameter and cover the entire sclera (the white part of the eye) rather than just the cornea. This provides several benefits for people with certain eye conditions.
Scleral contact lenses can be an excellent option for people with severe dry eye, as they trap a layer of tears between the contact lens and the eye. This helps to keep the eyes moisturized and can provide relief from dryness and irritation. Scleral lenses can also be prescribed for people with irregularly shaped corneas, such as those with keratoconus.
| Scleral Contact Lenses | Other Contact Lenses |
|---|---|
| Cover the entire sclera | Typically only cover the cornea |
| Can be an option for people with severe dry eye or irregularly shaped corneas | May not be ideal for people with these conditions |
| Can provide sharper vision than soft contact lenses | May not provide as clear of vision as RGP lenses |
While scleral contact lenses may not be the best option for everyone, they can be an excellent option for people with certain eye conditions. If you are interested in scleral contact lenses, talk to your eye doctor to see if they are a good option for you.
