About this tool
Eye Vision is a free online visual effect. Simulate the human eye's lens accommodation and lens imaging principles interactively. Interactive eye-candy rendered live on your screen. It runs entirely in your browser — no download or sign-up needed.
After opening the page, a vision test interface will be displayed, where you can switch between different visual defect modes: color blindness (red-green color blindness, blue-yellow color blindness), astigmatism (light divergence), myopia (blur), presbyopic (near blur), etc. Each mode changes the display effect of the screen in real time.
The whole process is pure front-end animation, based on CSS filters and Canvas image processing, simulating the effects of various visual defects in real time. The interaction is smooth and the effect is realistic.
It is suitable for use as visual science, helping normal people understand the feelings of patients with visual defects, or testing their own visual health. The implementation principles are color matrix transformation and Gaussian blur.
Visual simulation is an interactive special effect that simulates the visual defects of the human eye, including the true restoration of visual effects such as color blindness, astigmatism, and myopia.
