We strive to create a society in which all its members have equal rights and opportunities, including access to open information and the ability to use it. There are about 250 million visually impaired people in the world. They are not on the same footing with other members of society in using Internet resources that are not adapted to their demands.
Weak vision is a broad concept that comprises various visual impairments. Symptoms may be different:
With all the variety of symptoms, they have the main thing in common – they can’t be corrected either by surgery, or medication or with the help of contact lenses/glasses.
In the context of Internet resources, it means that the website must meet specific requirements to make visually impaired people use web content comfortably.
The goal: Web content should be accessible to for visually impaired people also, people with musculoskeletal system disorders.
Implementation method: an international standard WAI-ARIA has been developed.
Adaptedness: nowadays, all popular web-browsers have accessibility settings and support WAI-ARIA eye markers to enable full-blow use of the Internet for visually impaired people.
The “accessibility” version is implemented by adding features that make it easier to perceive information. Types of adapted Internet resources are divided into 3 levels of accessibility for the visually impaired category:
The list of recommendations for developers:

In this case, you can find an example of the visually impaired accessible version – npu.gov.ua. The resource is designed in accordance with the requirements of WCAG 2.0. |
1. The site is displayed in black and white, according to standard A.
2. After the transition to the adaptive mode, all images are hidden, except for the National Police of Ukraine symbol, which is displayed in shades of gray.
3. Elements of forms, images, and navigation contain text descriptions.
4. Resolving capacities of all paged are saved for all sections, both for desktop, tablet, and for a mobile version.
5. Sequential browsing experience through controls and navigation components is achieved by pressing the Tab key on the keyboard.
6. Implemented markup for screen reader.
It is possible to adapt a website to a visually impaired accessible version without interfering with the site architecture. Let’s mention the following features:
Please, note that the visually impaired accessible version has a number of disadvantages compared to the standard page:
Although the WCAG 2.0 standard was developed quite a long time ago, it is still challenging to find a website with a high accessibility version. High-quality implementation is rather an exception.The resources and experience available to Evergreen provide an opportunity to adapt a resource for visually impaired people quickly and efficiently.
The Evergreen team can quickly adapt a website for comfortable use for visually impaired people!
