For more than thirty years, contact lenses have been an option for those who want the versatility, depth perception, and peripheral vision lacking in traditional eyeglasses. Available in hard and soft varieties, contact lenses are thin prescription-grade discs that fit over the cornea to dramatically improve vision. If you are tired of your glasses and want to try contact lenses to improve your vision, contact our experienced optometrist, Dr. deMello, at our office in Wilmington, Delaware. He has extensive experience fitting contact lenses of all types for all patients, from children to adults.
Contact lenses are not only a helpful alternative to eyeglass for improving the vision of healthy eyes, they are also used to help correct the vision of those with eye diseases, such as keratoconus—a degenerative corneal disorder. An alternative to refractive surgeries , contact lenses offer a practical, comfortable, and easy way to correct vision while remaining free from eyeglasses
Types of Contact Lenses
Contact lenses are available in two types. Each has advantages and disadvantages. The main advantage that soft contact lenses have over rigid lenses is the initial comfort, and the ease with which you can switch back and forth from eyeglasses to contact lenses. For some patients, rigid lenses provide sharper vision. Dr. deMello and the optometrists at Eye Physicians and Surgeons, P.A. in Wilmington, Delaware will discuss your options and help you choose an option that fits your needs and lifestyle.
Soft Contact Lenses
Soft contact lenses are thin, flexible discs that absorb water, allowing them to sit comfortably in the eye for extended periods of time. Advancements in technology allow the newest generation of soft contacts to be infused with more moisture, ensuring a more comfortable fit even when worn for longer periods of time.
Most brands of soft contact lenses are disposable, meaning that you wear them for as long as the box advises—1 day to 2 weeks—and then throw them away, replacing them with a fresh new pair. Some brands are also approved for overnight wear, though this method may increase the risk for infection in certain patients. Though not a replacement for sunglasses, many brands of soft contact lenses have ultraviolet blocking built into the lens to help prevent UV rays from harming your eyes. UV light is a leading cause of cataracts and macular degeneration.
Rigid Gas Permeable Lenses
RGP contact lenses are made of rigid, gas permeable plastic, which allows oxygen to flow more freely to nourish the cornea, a significant improvement from previous generations of hard contact lenses. Since RGP lenses do not absorb possible contaminants from the hands or proteins that naturally occur in the eye, a single pair of hard contact lenses may last several years. These lenses can also be custom made to correct a variety of eye and vision problems.
Contact Lens-related Infections
Infections can occur with improper handing of the contact lenses. A careful fitting by an experienced professional, such as Dr. Tuyen or Dr. deMello, and thorough training in insertion, removal and cleaning, is critical to the safe use of contacts. For example, chemicals, make-up and hairspray can be irritants, and swimming in the ocean or exposure to tap water can introduce bacteria into the eye. Smoking not only hurts your lungs, it also dries out your eyes, which can make wearing contact lenses an uncomfortable experience. Always practice good hygiene and storage to keep your contact lenses clean and your eyes infection-free. In fact, under certain circumstances, Refractive Surgery can be a safer, as well as more convenient, alternative.
