Visual Screening Tests for Infants and Children
What is Vision Testing?
You might need to have an eye exam if you want to know whether your eyes are working perfectly fine or if you’re experiencing a vision problem. Part of a comprehensive eye exam is taking vision tests. This is important as vision tests check many different functions of the eye and detect possible problems that may arise. The earlier an eye problem is addressed, the earlier your eye doctor can provide you with solutions as to how treat it.
The most common vision test is the visual acuity test and the two common visual acuity test are Snellen and random E. In Snellen, a chart of letters or symbols is used. The letters are in different sizes and are arranged in rows in columns. In taking this test, you will be standing a few feet away from the chart while covering one eye and you will try to see the letters and symbols. You will repeat the same process with your other eye.
In the Random E test, you will try to identify the direction the letter “E is facing. You will look at the letter “E” in the chart and determine whether the letter is facing up, down, left, or right.
It is important to take note that the type of vision test you will take will depend on your doctor and the vision problem you have.
