Depth perception is the ability to accurately judge the distance between objects. It is an important skill for everyday life, as it helps us to navigate our environment and interact with others. If you have difficulty seeing distance, a depth perception test can help you determine if your eyes are working together to see in three dimensions. There are many different types of depth perception tests, but one of the most common is to use a pair of three-dimensional glasses to look at a brochure with test patterns.
Your task is to point out which of the several circles in each pattern looks closer to you than the others. If you can correctly identify the “closest circle” in each pattern, your eyes are likely to better perceive depth. Depth perception tests can be done at home or in an optometrist's office. At home, you can use a variety of objects such as books, toys, or other items that have different sizes and shapes.
Place them at different distances from you and try to identify which one is closest. In an optometrist's office, you may be asked to look at a chart with various shapes and sizes and identify which one looks closest. You may also be asked to look through a device called a stereoscope, which uses two images that appear slightly different when viewed separately. When viewed together, they create a three-dimensional image that can help determine how well your eyes work together. Depth perception tests are important for determining how well your eyes work together and if there are any vision problems that need to be addressed.
If you have difficulty seeing distance, it is important to get tested by an optometrist so that any vision problems can be identified and treated.
