Test for visual processing disorders with this free eye test:
Free Eye Test & Visual Processing
Test for spatial and visual processing capacity, based on a popular neuroscience lab project. Remember the sequence of objects that appear in the grid below, and then duplicate this sequence. Most people are able to remember 5 to 8 blocks in a row. Users can change the “Span” of objects displayed below.
To make this test more challenging, switch from Forward to Reverse order, and change the test speed from Slow to Fast. Click on the “New Test” button to begin.

Visual Processing and Learning Disabilities
Visual processing problems are not considered to be a learning disability, but they can impact how people resolve a learning disability.
There are eight different types of visual processing issues, and people can have more than one. These issues often go undetected because most don’t show up on standard vision tests.
Visual discrimination issues: Difficulty seeing the difference between two similar letters, shapes or objects. So they may mix up letters, confusing d and b, or p and q.
Visual figure-ground discrimination issues: Difficulty identifying a shape or character from its background. They may have trouble finding a specific piece of information on a page.
Visual sequencing issues: Difficulty telling the order of symbols, words or images. They may struggle to write answers on a separate sheet or skip lines when reading. They also may reverse or misread letters, numbers and words.
Visual-motor processing issues: Difficulty using feedback from the eyes to coordinate the movement of other parts of the body. Writing within the lines or margins can be tough.
Long- or short-term visual memory issues: Difficulty recalling with what has been seen. May struggle with reading and spelling. May also have trouble remembering what they’ve read and using a calculator or keyboard.
Visual-spatial issues: Difficulty telling where objects are in space. That includes how far things are from them and from each other. It also includes objects and characters described on paper or in a spoken narrative.
Visual closure issues: Difficulty identifying an object when only parts are visible. They may not recognize a truck if it’s missing wheels, or a person in a drawing that is missing a facial feature. May also have great difficulty with spelling because they can’t recognize a word if a letter is missing.
Letter and symbol reversal issues: Unprompted switching letters or numbers when writing. Can also have trouble with letter formation that affects reading, writing and math skills.
