These test aim to analyze your eyes and provide accurate assessment of how well you can see. These tests vary from popular ones, like having you read an eye graph, to intricate examinations, such as making use of a high-powered lens to check out the tissues within your eyes.

Comprehensive Eye Exams

Routine eye and vision exams are an important part of preventive health maintenance, whether your a child or an adult. Numerous eye and vision conditions have no evident signs or symptoms. Because of this, patients are frequently blind to the fact that concerns are present. Early diagnosis and treatment of eye and vision conditions are very important for preserving good vision and eye health, and when attainable, reducing the chances of vision loss. A thorough adult eye and vision exam may include, but is not limited to, the following tests. Unique patient signs and symptoms, as well as the skilled judgment of the optometrist, might greatly influence the tests the eye doctor chooses to use.

Patient History

A patient history helps to determine any type of symptoms the patient is experiencing, the time they began, the existence of any kind of overall heath conditions, medications being taken and occupational or environmental conditions that may be impacting sight. The eye doctor may ask questions relating to any eye or vision troubles you may be having, and about your overall health. The doctor may also inquire about any previous eye or health issues that you and your family may have experienced.

Visual Acuity

Reading charts are typically used to determine visual acuity. Visual acuity measurements analyze how accurately each eye is seeing. As an aspect of the testing, you will be asked to read letters on far and near reading charts. The final results of visual acuity testing are written as a fraction like 20/40.

When assessing distance vision, the top number in the fraction is the usual distance at which the evaluation is done, twenty feet. The lower number is the smallest letter size you managed to read. A patient with 20/40 visual acuity would need to get within 20 feet of a letter that should be seen at 40 feet for them to view it clearly. Normal distance visual acuity is 20/20.

Preliminary Tests

Preliminary testing could feature assessment of particular parts of visual function and eye health such as depth perception, color vision, eye muscle movements, peripheral or side vision, and how your pupils respond to light.


This kind of examination checks the curvature of the cornea, the clear outside area of the eye, by directing a circle of light on the cornea and checking its reflection. This measurement is especially essential in figuring out the ideal fit for contact lenses.


Identifying refractive error with a phoropter and retinoscope

Refraction is conducted to figure out the suitable lens power called for to compensate for any refractive error (nearsightedness, farsightedness, or astigmatism). Working with an instrument known as a phoropter, your optometrist places a number of lenses before your eyes and determines how they focus light making use of a hand held lighted instrument referred to as a retinoscope. The optometrist may decide to use an automated instrument that automatically evaluates the focusing power of the eye. The power is then fine-tuned by the individual’s feedback to determine the lenses that permit the clearest sight.

This testing may be performed without the use of eye drops to establish how the eyes react under typical seeing conditions. In some cases, for instance for people who aren’t able to answer verbally or when part of the eyes focusing power may be hidden, eye drops are utilized. The drops briefly keep the eyes from changing focus while the examination is conducted.

Eye Focusing, Eye Teaming, and Eye Movement Testing

Evaluation of accommodation, ocular motility and binocular vision establishes how successfully the eyes focus, move and work as a team. In order to attain a precise, single image of what is being viewed, the eyes must successfully adjust focus, move and function in unison. This assessment will find problems that keep your eyes from focusing efficiently or make using both eyes simultaneously difficult.

Eye Health Evaluation

Tonometry measures eye pressure. Elevated pressure in the eye indicates a heightened danger for glaucoma. External observation of the eye includes assessment of the cornea, eyelids, conjunctiva and encircling eye tissue working with intense light and magnification. Examination of the lens, retina and posterior part of the eye may be undertaken with a dilated pupil to show a clearer perspective of the internal structures of the eye.

Measurement of pressure within the eye (tonometry) is performed at a comprehensive eye exam. Normal eye pressures range from 10 to 21 millimeters of mercury (mm Hg), averaging about 14 to 16 mm Hg. Any individual with eye pressure greater than 22 mm Hg is at a raised chance of developing glaucoma, although many individuals with common pressure also develop glaucoma.

Additional testing

Further evaluations could be needed based on the results of the earlier tests to verify or preclude possible problems, to illuminate ambiguous results, or to offer a more detailed evaluation.

At the conclusion of the exam, your optometrist will assess and review the final results of the testing to establish a diagnosis and develop a treatment plan of action. Your optometrist will explain the symptoms and causes of every optical or eye health issue discovered and explain available treatment approaches. Sometimes, referral for consultation with, or treatment by, another optometrist or other health care specialist might be indicated.

If you have inquiries concerning any eye or vision disorders diagnosed, or treatment advised, don’t ever hesitate to ask for further information or explanations from your eye doctor.
