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, the vision test interface will be displayed. You can switch between different visual defect modes: color blindness (red and white color blindness, blue and yellow color blindness), astigmatism (light divergence), myopia (blurred), presbyopia (near blurred), 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 to help normal people understand how people with visual disabilities feel or to test 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.
