Which accessibility feature helps users with visual impairments?

High contrast display is an accessibility feature designed specifically to enhance visibility for users with visual impairments. By adjusting the colors on the screen to create a stark contrast between the text and the background, it significantly improves readability. This is particularly beneficial for individuals who may have difficulty distinguishing colors or who experience low vision, making it easier for them to interact with the content on the screen.

Other options, while related to different aspects of technology, do not specifically aid users with visual impairments. Mouse keys assist those who may have difficulty using a standard mouse by allowing control of the cursor through the numeric keypad. File encryption is focused on securing data privacy and protection, unrelated to accessibility. Data recovery pertains to recovering lost or corrupted data, and likewise does not address visual accessibility needs.
