What Is Vision Screening?
Vision screening is a routine eye exam that can help to assess whether any eye problems are present. The purpose of vision screening is to prevent, diagnose, and treat any eye conditions.
How Is Vision Screening Performed?
Vision screening is a process that many establishments including schools and driving test centers, perform. It involves a series of tests executed by the examiner with the use of selected eye tools. The tests may vary depending on the person and their history.
Some of the tests include:
Corneal Light Reflex Testing
With a vision screener, these tests occur in one comfortable setting. There is no fumbling around with different equipment or tools. A vision screener carries all the functions and capabilities necessary to administer each vision screening test mentioned above.
Vision Screener Functions
While there are many degrees of screenings available, consistency and accuracy are essential for eye health. For this reason, there are some essential functions that every vision screener should have.
1. Acuity- A test that involves reading a chart of numbers and letters of varying sizes to determine the accuracy of vision.
2. Ambler- A grid chart that can help to establish the presence of macular degeneration and other eye diseases that could potentially cause vision loss.
3. Refractive Errors- This test checks common vision problems such as astigmatism, nearsightedness, and farsightedness. This test can help to determine whether glasses/contact lenses are needed.
4. Depth Perception- a 3D imaging test to assess whether the binocular vision is efficient and to rule out possible “lazy eye.”
5. Colors- Checks for color blindness, which is the inability to distinguish between certain colors.
6. Contrast- Checks for the ability to recognize light and dark contrast, this test can be particularly helpful in diagnosing cataracts.
7. Complete Visual Field- An eye examination that can detect dysfunction in central and peripheral vision which may lead to medical conditions such as glaucoma, stroke, pituitary disease, brain tumors or other neurological issues.
Are Vision Screenings Accurate?
Vision screening can assist in identifying visual impairments to decide whether a referral to a specialist is required. However, screenings and vision tester equipment vary greatly, and many checks must be made for the screening to be a truly effective method of eyesight assessment.
