Eye Exam Process

eye exam west chester paA comprehensive eye exam differs from a vision screening. The latter only tests visual acuity and is commonly performed by a school nurse, optician, pediatrician or other healthcare providers.

What Tests Are Done During An Eye Exam?

In order to evaluate the eyes thoroughly and detect any problems, the following tests are performed by an eye doctor during an eye exam:

  • Visual Acuity
  • Visual Field
  • Retinal Examination Under Pupil Dilation
  • Slit-Lamp
  • Tonometry (Tests Intraocular Pressure (IOP))
  • Keratometry (Measures Curvature of Cornea)
  • Refraction

Tonometry checks for the presence of glaucoma, and keratometry for astigmatism. All of the above eye exam tests are safe for all patients.

Common Refractive Errors Found during Eye Exams


Also known as nearsightedness or shortsightedness, myopia is a condition of the eyes in which nearby objects are clear, and distant objects are blurry. Almost a third of people in the United States have some degree of nearsightedness.


Astigmatism occurs when curvature of the eye is irregular. There are two types of astigmatism: corneal, in which the shape of the cornea (the clear covering of the eye) is irregular, and lenticular, in which the lens is imperfectly shaped. Corneal astigmatism is more common. Astigmatism can result in blurred vision at any distance.


Also known as farsightedness, hyperopia is a condition of the eyes in which the focus on distant objects is better than the focus on objects closer to the eye, making nearby objects appear blurry. The eye is designed to focus images directly on the surface of the retina; with hyperopia, light rays focus behind the surface of the retina, producing a blurry image.


Presbyopia, meaning “old eye,” is a condition in which the eyes lose their ability to focus on close objects. It is considered a normal part of the aging process. Symptoms typically begin when patients are between 40 and 45 years old.

Can Refractive Errors be Corrected?

All of these vision conditions can be effectively treated with either eyeglasses or contact lenses. Corrective lenses may need to be used only during certain activities, such as reading, watching television or driving, or may be needed at all times. To determine which treatment is right for you, schedule an eye exam appointment with an eye doctor at Vistarr Laser & Vision Centers.

Why Get Comprehensive Eye Exams Regularly

Early intervention is crucial in preventing vision loss from a disease such as glaucoma, which may not cause symptoms until significant and irreversible damage has taken place. Early detection of eye problems by an eye doctor gives a patient a choice of treatment options and reduces the risk of permanent damage.
