Presbyopia

An age-related vision condition where the eye gradually loses its ability to focus on nearby objects, typically becoming noticeable in the early to mid-40s. Presbyopia affects virtually everyone as they age and significantly impacts web accessibility, making small text difficult to read and requiring users to hold devices at arm's length. Web design accommodations include adequate base font sizes (at least 16px), resizable text that maintains layout when enlarged up to 200%, sufficient line spacing, and avoiding text in images. Unlike other visual impairments, presbyopia is universal with age rather than a disability, reinforcing that accessible design benefits everyone.
