Contact lenses are a great form of vision correction. Two general categories of contact lenses are soft and rigid gars permeable (RGP). Contact lenses come in different types and colors, and can be used to correct different forms or vision disorders such as Myopia (nearsightedness), Hyperopia (farsightedness), Astigmatism, and Prespyopia (having difficulty when reading things closely).
Advantages about contact lenses: There are approximately 35 million contact lens wearers in the United States. It has been a great vision correction method for people who are looking for alternatives from regular eyeglasses mainly for their flexibility and convenience. The most common advantages we observe from our patients are:
If contact lenses are not properly cared for, it can lead to infection or discomfort (dryness, foreign body sensation, itchiness, etc).
Under the Food and Drug Administration regulation, all contact lenses in the U.S. require a valid prescription. They should be worn, cleaned, and replaced properly as prescribed by professional optometrists. The Ocular Surface Institute is here to educate all of our patients and study participants how to maintain safe, comfortable contact lens wear.

Dry eye disease is generally thought be due to a decrease in tear production or an increase in the evaporation of tears. Tears keep the surface of the eye wet and drains out debri that may fall into the eye, so without the tear film the eye is no longer protected.
Dry eye disease can be caused by many different factors. Some examples include hormonal changes due to aging, or living in an environment of low humidity for long periods of time. No matter what the cause of dry eye, a common side effect is irritation of the tissues on the surface of the eye and the glands that produce tears. Certain types of blood cells (white blood cells) that normally travel in your blood stream can pass into irritated eye tissue. These white blood cells help to fight infection and can release inflammatory substances (inflammatory molecules and chemicals) that can damage eye tissues and glands. This may lead to the development of dry eye disease.
Symptoms of dry eye include but are not limited to foreign body sensation, itchiness, irritation, discomfort, blurry vision, pain, and eye fatigue. Mild symptoms may be slightly discomforting, but severe dry eye can be disruptive in every day activities; therefore, catching dryness early is very beneficial.
