About Peripheral Vision
Peripheral vision refers to what you can see outside the center of your gaze. It's critical for:
- Detecting movement and potential threats
- Spatial awareness and navigation
- Sports performance and driving safety
Conditions like glaucoma, retinitis pigmentosa, and stroke can affect peripheral vision. Regular eye exams can help detect these issues early.
