The contact lens fro dry eyes tries to make sure that it won’t cause corneal scars and damage to eye tissues. Since the eyes fail to produce enough tears, thus it is unnourished and does not have stable tear firm. Leading manufacturers and brands continue to invest on research and technology to make sure they can make the proper contact lens for dry eyes. They employ different materials like polymers and gels that has long water retentions.
Contact lenses for dry eyes are made from special compounds that keep the dryness in check and serve a special purpose. Silicone hydrogel not only controls water buildup but it gives a soothing effect to the eye. It provides moisture despite having lesser water.
Silicone hydrogel lenses are made up of materials that have high oxygen permeability, very ideal for the cornea.
New polymers are being developed and employed to combat dryness problems. One polymer that manufacturers developed with biocompatible contact lenses is Omarfilcon A. It is specifically designed to fit comfortably and adjust to the characteristics of the eyes.Hydrophilic polymers is the main component of soft contact lenses, it keeps the lens moist and easy to wear. These lenses would make sure your eyes are properly hydrated.
It is also important to note that rigid gas permeable lenses are good contact lenses for dry eyes. It does not dehydrate the eye because this type of contact lens of rigid plastic. The plastic that makes up gas permeable lenses is oxygen permeable.
Just a reminder, it is wiser to visit an eye practitioner to check if you are suffering from dry eyes. To avoid eye complications, you must make sure that you follow all the instructions given by the eye care practitioner.
