Can Scleral Lenses Improve My Eyesight?

a scleral lens is a high-contrast

If you need vision correction, but you have had poor results with contact lenses, you may want to consider the use of scleral lenses. Also called clear lenses, a scleral lens is a high-contrast, rigid contact lens which rests directly on the sclera in the eye and produces a tiny tear-shaped vault above the cornea. Unlike traditional, contact lenses, which can be worn with any eye color, scleral lenses must be worn with a specific color of vision condition in order to correct that vision condition. The FDA has approved the use of scleral lenses for correction of myopia, hyperopia, and astigmatism. Scleral multifocal lenses, or scleral contacts, have also been approved by the FDA for this purpose. These lenses are available for sale in retail stores and via online retailers.

The primary function of scleral lenses is to reduce the eye’s sensitivity to light, which can be undesirable in some conditions, including nearsightedness, farsightedness, presbyopia, and astigmatism. In addition, they can help to improve the eyes’ drainage of waste products from the upper respiratory tract, and they may help prevent some irritations, such as itching and redness, that occur when the eye is irritated by foreign matter. The sclera is the sclera, or top of the eye, and therefore they are normally clear. However, in some conditions, such as cataracts, the sclera may be mildly stained or browned, and the oxygen permeable layer may be thinning or breaking, allowing some light to pass through, causing blurry vision and increased discomfort.

to improve visual clarity while restricting the growth of wrinkles and improving dry eye

Since the goal of scleral lenses is to increase visual clarity, it is important to note that some people experience adverse responses to them. For example, those with nearsightedness may notice an increase in glare or blurred vision, but will not suffer from discomfort. Scleral design also causes some irregularities to the front surface of the eye, causing pain and irritation if they rub or are rubbed on the eyelids, but since they are designed to improve vision, most users do not experience this discomfort.

Another type of corrective surgical procedure available to improve visual clarity while restricting the growth of wrinkles and improving dry eye is through the use of rigid gas permeable lenses. Unlike scleral lenses, rigid gas permeable lenses have a thin layer of gas within the eye itself. This allows the eye to retain a better balance of oxygen and carbon dioxide, which can cause dry and flaky eyes, which is why this is an easier and safer alternative. However, the benefits of this type of corrective eye surgery come with some risks, including potential damage to the eye’s delicate structures and the potential for the eye to become overwhelmed by the gas, which can cause an allergic reaction.

One other issue that is often noted with patients using scleral lenses is the discomfort associated

In addition, patients who have undergone an ophthalmologist-recommended refractive surgery may experience the development of cataracts, if they have had their eyes done using scleral lenses. Cataracts occur when fluid builds up behind the lens in the eye and hardens into tiny capillaries surrounding the lens. This condition is known as “chronic cataracts” and can be very serious if left untreated. These types of problems can usually be corrected with glasses, but scleral lenses can help patients prevent the development of cataracts, reducing the risk of developing severe dry eye and eliminating the need for glasses. Furthermore, patients who wear scleral lenses may notice that their eyes feel fresh and are not as dry and as congested as before, which can help reduce the need for glasses.

While some people report a slight stinging sensation when using several lenses, other patients note irritation or a burning sensation, leading many doctors to believe that this discomfort is caused by the material the scleral material is placed over. The materials that are typically used for scleral lenses are polycarbonate and hydroscopic silicon hydrothermal resin, which have been shown to cause less irritation to patients’ eyes than other materials. Additionally, these materials are hypoallergenic, meaning that they do not irritate the eye like other materials commonly used in contact lenses. These factors make scleral lenses an excellent choice for patients who are concerned about their eye’s comfort and overall appearance.
