General Questions

Answers to General Questions


What Is 20/20 Vision?

20/20 vision is a term used to express normal visual acuity (the clarity or sharpness of vision) measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at 100 feet.

What Is Myopia?

Nearsightedness, or myopia as it is medically termed, is a vision condition in which near objects are seen clearly, but distant objects do not come into proper focus. Nearsightedness occurs if your eyeball is too long or the cornea has too much curvature, so the light entering your eye is not focused correctly.

What Is Hyperopia?

Farsightedness, or hyperopia as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus. Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly.

What Is Presbyopia?

Presbyopia is a vision condition in which the crystalline lens of your eye loses its flexibility, which makes it difficult for you to focus on close objects. Presbyopia may seem to occur suddenly, but the actual loss of flexibility takes place over several years. Presbyopia usually becomes noticeable in your early to mid-40s. Presbyopia is a natural part of the aging process of the eye. It is not a disease and it cannot be prevented.

What Is Astigmatism?

Astigmatism is a vision condition that occurs when the front surface of your eye, the cornea, is slightly irregular in shape. This irregular shape prevents light from focusing properly on the back of your eye, the retina. As a result, your vision may be blurred at all distances.

Why Do I Need an Eye Exam Every Year?

Periodic optometric examinations are an important part of routine preventive health care. Many eye and vision conditions present no obvious symptoms. Therefore, individuals are often unaware that a problem exists. Early diagnosis and treatment are important for maintaining good vision and, when possible, preventing permanent vision loss. Read more here.

Why Do I Need a Contact Lens Evaluation Every Year?

Contact lenses are among the safest forms of vision correction when patients follow the proper care and wearing instructions provided by their eye doctor. However, when patients don’t use lenses as directed, the consequences may be dangerous. In fact, contact lens wearers could be damaging their eyes by not using proper hygiene in caring for their lenses.


Contact lenses and the solutions used with them are medical devices and are regulated by the Food and Drug Administration. It is extremely important that patients maintain regular appointments to ensure they are receiving clinical guidance from their eye doctor based on individual eye health needs. Read more.

What Are Cataracts?

A cataract is a clouding of the lens in the eye, which affects vision. Most cataracts are found in persons over age 55, but they are also occasionally found in younger people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery. Read more here.

 What Are Dry Eyes?

The tears your eyes produce are necessary for overall eye health and clear vision. With dry eyes, your eyes do not produce enough tears or you produce tears that do not have the proper chemical composition. Often, dry eyes are a part of the natural aging process. It can also be caused by blinking or eyelid problems, medications like antihistamines, oral contraceptives and antidepressants, a dry climate, wind and dust, general health problems like arthritis or Sjogren’s syndrome and chemical or thermal burns to your eyes.


If you have dry eyes, your symptoms may include irritated, scratchy, dry, uncomfortable or red eyes, a burning sensation or feeling of something foreign in your eyes and blurred vision. Excessive dry eyes may damage eye tissue, scar your cornea (the front covering of your eyes), impair vision and make contact lens wear difficult. Read more here.

What Is Glaucoma?

Glaucoma is an eye disease in which the internal pressure in your eyes increases enough to damage the nerve fibers in your optic nerve and cause vision loss. The increase in pressure happens when the passages that normally allow fluid in your eyes to drain become clogged or blocked. The reasons that the passages become blocked are not known. Read more here.

What Is Macular Degeneration?

Macular degeneration is the leading cause of blindness in America. It results from changes to the macula, a portion of the retina that is responsible for clear, sharp vision, located at the back of the eye. Most people with macular degeneration have the dry form, for which there is no known treatment. The less common wet form may respond to laser procedures, if diagnosed and treated early.


Some common symptoms are a gradual loss of ability to see objects clearly, distorted vision, a gradual loss of color vision and a dark or empty area appearing in the center of vision. Read more here.

What Is Keratoconus?

Keratoconus is a vision disorder that occurs when the normally round cornea (the front part of the eye) becomes thin and irregular (cone-shaped). This abnormal shape prevents the light entering the eye from being focused correctly on the retina and causes distortion of vision.

What Is Sports Vision?

Vision, just like speed and strength, is an important component in how well you play your sport. And there is much more to vision than just seeing clearly. Your vision is composed of many interrelated skills that can affect how well you play your sport. Just as exercise and practice can increase your speed and strength, it can also improve your visual fitness and accuracy. Sports vision training works on improving the visual abilities of an athlete.

What Are Floaters?

Spots (often called floaters) are small, semi-transparent or cloudy specks or particles within the vitreous, which is the clear, jelly-like fluid that fills the inside of your eyes. They appear as specks of various shapes and sizes, threadlike strands or cobwebs. Because they are within your eyes, they move as your eyes move and seem to dart away when you try to look at them directly.


Spots are often caused by small flecks of protein or other matter trapped during the formation of your eyes before birth. They can also result from deterioration of the vitreous fluid, due to aging, or from certain eye diseases or injuries. Most spots are not harmful and rarely limit vision. But, spots can be indications of more serious problems, and you should see one of our optometrists for a comprehensive examination if you notice sudden changes or see increases in them.

What Is Diabetic Retinopathy?

Diabetes is a disease that interferes with the body’s ability to use and store sugar and can cause many health problems. One health problem, called diabetic retinopathy, can weaken and cause changes in the small blood vessels that nourish your eye’s retina, the delicate, light-sensitive lining of the back of the eye. These blood vessels may begin to leak, swell or develop brush-like branches.


The early stages of diabetic retinopathy may cause blurred vision or they may produce no visual symptoms at all. As the disease progresses, you may notice a cloudiness of vision, blind spots or floaters. If left untreated, diabetic retinopathy can cause blindness, which is one reason why it is important to have your eyes examined regularly by one of our doctors. This is especially true if you are a diabetic or have a family history of diabetes.

What Is CRT?

CRT is a specially designed, oxygen-permeable therapeutic contact lens used in Corneal Refractive Therapy. Corneal Refractive Therapy is a sophisticated, non-surgical process that reshapes the cornea while you sleep. You remove the lenses when you are awake and able to go through the day without any other correction.

What Is LASIK?

LASIK, or Laser In-Situ Keratomileusis (meaning to shape the cornea of the eye using laser), is an advanced laser procedure for correcting nearsighted, farsighted and astigmatic vision. Read more.


This procedure is performed by an ophthalmologist using anesthetic eye drops that completely numb the eye, eliminating the use of needles. The surgeon begins by creating a micro-thin protective flap. The surgeon then uses state-of-the-art laser technology to gently sculpt the cornea for the intended purpose of reducing or eliminating the need for corrective lenses. The protective flap is then replaced and heals instantly without the need for any stitches.

What Is Vision Therapy?

Vision therapy is a progressive form of exercise and procedures for the eyes. It is a highly effective, non-surgical treatment for many common visual problems such as lazy eye, crossed eyes, double vision, problems with hand-eye coordination and some reading and learning disabilities.
