Vision Tests — Free Online Eye & Color Tests

Your visual system processes more information than any other sense, and individuals vary measurably in their color vision, fine color discrimination ability, and peripheral field width. These vision tests screen for common visual differences directly in your browser, without specialist clinic equipment or any download.

The Color Blind Test uses Ishihara-style plates — circles filled with colored dots that conceal numbers visible only to people with normal color vision. It screens for the most prevalent forms of color vision deficiency: red-green color blindness, which affects approximately 8% of men and 0.5% of women globally. The Color Hue Test challenges your fine color discrimination by asking you to arrange colored tiles in smooth hue order — a variant of the Farnsworth-Munsell 100 Hue Test used in professional color-grading and paint-matching industries. The Peripheral Vision Test measures the usable width of your visual field by detecting your response to stimuli appearing at progressively greater eccentricities from your central fixation point.

These are screening tools, not clinical assessments. They provide useful preliminary information about your visual system, but any concerns about visual health — sudden field loss, rapid color vision changes, or persistent visual disturbance — should be evaluated promptly by an optometrist or ophthalmologist. For the most accurate results, test in good natural lighting and when your eyes are well-rested.
