Eye and Vision Examination

Routine eye and vision examinations are imperative to preventive health care. Many eye and vision problems have no glaring signs or symptoms. Hence, people are often unaware of existing problems. Early diagnosis and treatment of vision problems maintain good vision and eye health and prevent vision loss when possible.

A comprehensive adult eye and vision examination are not limited to the following tests. Individual patient signs, symptoms, and the doctor’s professional judgment, may significantly influence the testings.

  • Patient History

    Patient history records symptoms experienced at the beginning in the presence of any general health problems, medications taken, and occupational or environmental conditions affecting vision. Our doctor enquires about any eye or vision problems, your overall health, any previous eye or health conditions about you and your family members.

  • Visual Acuity

    It evaluates the clarity of each eye’s vision. As part of the testing, you must read letters on distant and near reading charts. The results are written as a fraction, such as 20/40.

    When testing distance vision, the top number in the fraction is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read. A person with 20/40 visual acuity would have to get within 20 feet of a letter that should be seen at 40 feet to see it clearly. Normal distance visual acuity is 20/20.

  • Preliminary Tests

    Preliminary testing evaluates the visual function and eye health aspects such as depth perception, color vision, eye muscle movements, peripheral or side vision, and how your pupils respond to light.

  • Keratometry

    To measure the cornea’s curvature, the clear outer surface of the eye, a circle of light on the cornea is focused on measuring its reflection, a critical part in determining the proper fit for contact lenses.

  • Refraction

    Refraction determines the appropriate lens power needed to compensate for any refractive error (nearsightedness, farsightedness, or astigmatism). Refraction is performed by placing a series of lenses in front of your eyes and measures how they focus light with a hand-held lighted retinoscope. An automated instrument can also automatically evaluate the eye’s focusing power, which is then refined by the patient’s responses to allow the clearest vision.

    The charge for Refraction may not be covered by all insurances. 

  • Evaluation of Extra Ocular Muscles

    The eyes’ smooth movement is tested by assessing accommodation, ocular motility, and binocular vision. To obtain a clear, single image of what is being viewed, the eyes must effectively change focus, move and work in unison. It looks for problems that keep your eyes from focusing effectively or make using both eyes together difficult.

  • Eye Health Evaluation

    External eye examination evaluates the cornea, eyelids, conjunctiva, and surrounding eye tissue using bright light and magnification. Lens evaluation, retina, and posterior section dilate the pupil to better view the eye’s internal structures.

    Eye pressure measurement (tonometry) is performed; the normal range is 10 to 21 millimeters of mercury (mm Hg). Eye pressure greater than 22 mm Hg may increase the risk of developing glaucoma. A complete evaluation will determine the relative risk and/or the need for treatment. 

  • Supplemental Testing

    Additional testing based on the results of the previous tests clarifies possible problems, uncertain findings, or an in depth assessment.

    Dr. Rubin will assess the results of the examination and any testing completed to determine a diagnosis and develop a treatment plan. He will discuss the pattern of any visual or eye health problems found and explain available treatment options. 

    If you have questions regarding any eye or vision conditions diagnosed or treatment recommended, get in touch for additional information or explanation from your doctor.

  • What is “Lazy Eye”?

    Amblyopia, or “lazy eye,” means unequal vision between the two eyes despite using corrective measures such as glasses, caused by unequal errors of refraction, misalignment of the eyes, or cloudiness in the line of vision due to conditions such as cataracts.

    Amblyopia may be reversible if detected at an early age and treated by patching the better-seeing eye or blurring its vision using atropine drops. It is the leading cause of unilateral vision loss in children and young adults.
