Some ocular conditions make it difficult for people to wear regular lenses. If you have dry eye or irregular corneas, you may benefit from scleral lenses. These are hard, large-diameter lenses that vault over the cornea, resting on the sclera. They are gas-permeable materials that are breathable to enhance comfort.
If you need lenses to correct your vision, you can choose between glasses and contacts. Many people choose contacts due to the convenience that they offer as they provide effective vision correction. Before you get contact lenses, you need to go through an eye examination.
Our eyes are very complex structures. One key component is the cornea. This is the clear, domed lens at the very front that protects the pupil and iris. It also serves to refract light as it enters the eye, bending it so that it is focused on the retina, which is the patch of light-sensitive cells found at the back of the eye. Normally, the cornea is a fairly regular dome shape. However, some people find that their cornea starts to bulge outwards in the shape of a cone. This condition is known as keratoconus.
Dry eyes occur when the tear glands in your eyes fail to produce enough tears. This condition leaves your eyes lacking in moisture and can be painful or uncomfortable. Dry eyes can be caused by environmental or medical factors. Certain daily activities such as wearing contacts and working with computers can aggravate the condition. Dry eyes can also be caused by allergies, exposure to dry air, and certain medications.
Have you been told you’re not suitable for contact lens wear? Perhaps you tried it but found wearing them difficult. If so, you may have eyes that are hard to fit. This means that you may have a condition that makes wearing contact lenses more challenging.
