It's important to choose the right type of contact lenses to get the best visual comfort.
Not everyone has the same needs, and each person must wear contact lenses that are specifically designed for their profile.
For example, some people are better off wearing scleral contact lenses.
Many people choose to wear contact lenses to correct a vision problem.
However, contact lenses come in different types, including soft and rigid.
Scleral contact lenses are large diameter, rigid surface lenses.
They are wider than the surface of the cornea, unlike soft lenses that only cover this area.
Scleral contact lenses get their name from the fact that they rest on an area of the eye called the sclera, also known as the white of the eye.
They are gas permeable, allowing oxygen to easily penetrate the cornea.
Scleral contact lenses contain a fluid that keeps the eye moisturised.
Because they are rigid, they stay in place, do not deform and can last a long time.
Scleral contact lenses are individually designed to fit the eye and meet the exact needs of the wearer.
A scleral contact lens requires regular care to ensure that it remains sterile, perhaps more so than a conventional soft lens.
Like soft contact lenses, scleral lenses can correct all types of vision problems.
As a matter of fact, they can correct myopia, astigmatism, presbyopia and hyperopia.
Therefore, the choice of scleral contact lenses is not based on the type of ametropia a person has, but rather on their specific visual profile.
In fact, scleral lenses are usually prescribed for corneal abnormalities such as keratoconus.
Scleral lenses may also be prescribed after refractive surgery.
This type of contact lens is also prescribed for people who suffer from dry eyes.
That's why it's important to have an eye exam before being prescribed contact lenses.
This eye examination will help determine your exact needs and the most suitable type of lens.
However, you should be aware that it takes longer to adapt to scleral contact lenses than to soft lenses and that they require special training.
What's more, although they last longer, they can also be more expensive.
Feel free to talk to your Optical Center optician to find out if scleral contact lenses are right for you.
