Contact lenses are a popular alternative to eyeglasses for correcting vision. They are small, plastic lenses that sit directly on the surface of the eye, and they can correct a wide range of vision problems, including nearsightedness, farsightedness, and astigmatism.
There are two main types of contact lenses: soft lenses and rigid gas-permeable (RGP) lenses. Soft lenses are made of a flexible, water-absorbing material that conforms to the shape of the eye. They are the most popular type of contact lens and are most commonly available in daily and monthly disposable options. RGP lenses are made of a harder, gas-permeable material that maintains its shape on the eye. There are some specialty lenses that utilize this material like scleral lenses and ortho-K lenses. RGP lenses are less common but are increasing in use for certain conditions such as keratoconus, dry eyes, and myopia control.
When fitting a patient for contact lenses, we will take several measurements of your eyes. Some of these measurements may include the size and shape of the cornea, the curvature of the cornea, and your prescription. We will then use these measurements to determine the appropriate type and size of lens for the patient.
If you are new to contact lenses, we will also teach you how to properly apply, remove, and care for the lenses. This includes how to clean and disinfect the lenses, proper solution to use, as well as how often to replace them.
Wearing contact lenses requires proper care and maintenance to avoid complications such as infection and irritation. Patients should be advised to follow good hygiene practices and to never share their lenses with others. They should also be advised to remove their lenses before sleeping, showering, swimming, or doing any activities that may cause the lens to dislodge from the eye.
Additionally, as a contact lens wearer, you may need to have follow-up appointments with us to monitor the health of your eyes and the fit of your lenses. This is important because contact lens wear can lead to changes in the eye over time. Dryness and inflammation are the most common changes which can affect the comfort and vision of the contact lens wearer.
Overall, contact lenses are a safe and effective option for vision correction, but it is important as a patients to work with our experienced optometrists and staff and to follow proper care and maintenance instructions to avoid complications.
