About This Condition

Peripheral vision loss narrows the usable field of view over time, often without early warning. Interfaces that place critical actions, labels, or alerts at the edges of the screen may be completely invisible, even when central vision remains functional.

Digital Challenges

Navigation menus, notifications, and action buttons positioned at screen edges fall outside the usable visual field. People with glaucoma may miss critical prompts entirely, leading to incomplete tasks, missed errors, and growing frustration with interfaces that assume full peripheral vision.

Assistive Technologies

• Screen magnifiers
• screen readers
• keyboard navigation

Design Considerations

Place all critical alerts, errors, and calls to action in the central visual zone. Avoid edge-only notifications. Use inline alerts adjacent to triggering elements and ensure screen reader announcements duplicate all visual feedback.

Clinical Examples

Open-angle glaucoma, angle-closure glaucoma, normal-tension glaucoma
