Google Chrome introduced a feature that allows to simulate disturbances when viewing web pages. The function is primarily intended for developers: when viewing the page, for example, color blindness and blurred vision in the window to change the color and sharpness that allows to efficiently configure these settings for people with disabilities. About this in his Twitter said one of the researchers of the company.
Some sites use special modes for people with visual impairments can increase the font of text, change the color scheme, to make the page brighter or darker. Despite the existence of ready-made solutions to adapt the pages, many of them do not cover all common vision disorders. The developers are not often thinking about how to adapt the site design for people with visual impairments because they do not always understand what and how things need to change in order to facilitate the perception of information for these visitors.
A new feature from Chrome you can enable on any page. Among the available visual impairments, which it simulates, there is a decrease in visual acuity, and various disorders of vision, including not only all known types of color blindness (e.g., the most frequent type — deuteranomaly, which interferes with the perception of colors in the red and green part of the spectrum), but the complete absence of color vision.
A function available in the menu for developers. Assessing the look of the web page through the eyes of people with visual impairments, developers can customize the appearance of your site. A similar function for developers have recently revealed Firefox.
