Regular eye exams are an invaluable tool in maintaining eye health by detecting and preventing disease. Some diseases, such as glaucoma, develop gradually without causing pain or vision loss, so patients may not notice that anything is wrong until significant and irreversible damage has been done. Early detection of eye diseases can allow for a choice of treatment options and reduced risk of permanent damage.

When Should I Get An Eye Exam?

Patients should see their doctor for a comprehensive eye exam every one to three years, depending on their age, risk of disease and overall physical condition. Children should have regular tests to ensure the proper development of their vision and prevent any interference with their academic achievements. Older adults are often at a higher risk for eye conditions such as glaucoma, macular degeneration and cataracts. Even if your eyes are healthy, you should still have regular eye exam to detect any problems as soon as possible and begin necessary treatment.

Who Should Get An Eye Exam?

An eye exam is different from a vision screening, which only tests vision and is commonly performed by a school nurse, pediatrician or other health care provider. Only your eye doctor can perform a comprehensive eye exam to evaluate the overall health of the eye and detect any changes that may indicate a vision disorder. During a routine eye exam, your doctor will evaluate your eyes for refractive errors, as well as common conditions such as:

  • Amblyopia
  • Strabismus
  • Presbyopia
  • Glaucoma
  • Diabetic eye disease
  • Cataract

This is done through a series of eye tests that examine all aspects of the eye, including visual acuity, dilation, glaucoma test, slit-lamp examination, cover test and refraction. These tests can all be performed in your doctor’s office and are safe for all patients.

After completing the comprehensive exam and coming to an accurate diagnosis, your doctor will develop a treatment plan based on the findings of the exam. This treatment plan usually includes a prescription for eyeglasses or contact lenses, medication, eye vitamins, vision supplements or surgery for serious conditions.

Common Eye Conditions

The most common eye conditions diagnosed during a comprehensive eye exam involve refractive errors that cause blurry vision for patients. These conditions affect millions of people in the US and often get progressively worse as patients age. Fortunately, refractive errors can be easily treated to let patients enjoy clear vision at all distances.

Or myopia, is a vision condition in which nearby objects are clear and distant objects appear blurry. This may be caused by excess corneal curvature or an oblong rather than aspherical shape to the eye, both of which affect the way light is bent upon entering the eye and whether or not it focuses properly on the retina.

Myopia affects nearly one-third of all people in the US to some degree, with symptoms usually appearing before the age of 20. Patients with myopia have difficulty focusing on objects in the distance, such as a chalkboard or TV.

Or hyperopia, is a condition in which the eye focuses on distant objects better than on objects closer to the eye, so nearby objects appear blurry. This happens when light rays refract, or bend, incorrectly in the eye. The eye is designed to focus images directly on the surface of the retina, but when the cornea is incorrectly curved light rays focus behind the surface, producing a blurry image.

Occurs when the cornea is curved slightly in one direction, causing blurred vision. While the cornea usually refracts to focus light on the retina, some of the light focuses in front of or behind the retina in patients with astigmatism. In addition to blurry vision, patients with astigmatism may also experience headaches, eye strain and fatigue. The severity of symptoms depends on the degree of astigmatism in the eyes.

Eye Exams

All of these vision conditions can be effectively corrected through eyeglasses and contact lenses. Eyewear may be used during certain activities, such as watching television or driving, or at all times. At our practice, we offer patients a wide selection of eyeglass frames and lenses in our optical shop.

For most residents of Philadelphia, eye exams should be scheduled regularly to keep the eyes healthy and free of any complications. Many of the most common eye diseases can be treated easily when caught early, but waiting too long can lead to permanent damage, including blindness. To avoid lasting consequences, call Allen C. Richmond, MD, P.C. for an appointment.

Though routine care is important for everyone, those in certain age groups need frequent tests. One example is children, whose eyes are constantly developing and may need some help in order to stay on the right track. The vision tests offered at school are just a small piece of the necessary care for children, as these do not detect developmental issues or diseases. Older patients are also encouraged to get regular care to avoid glaucoma, cataracts, and other visual issues that may include presbyopia, amblyopia, and strabismus.

Even healthy eyes may benefit from vitamins to improve vision, contacts to help correct astigmatism, or glasses to improve visual clarity. Regular eye exams can ensure that your eyes are always healthy and at their best, allowing you to see clearly while driving, reading, or just going about life.
