SONAR GLASSES by G-Technology Group increase mobility independence for blind and visually impaired people by helping them safely navigate around obstacles in their path of travel.

SONAR GLASSES will alert the user about potential hazards that are beyond the reach of a white cane, such as parked vehicles, overhanging branches, street and traffic signs, construction scaffolding, and other pavement obstacles.

Sonar Glasses are used in conjunction with the white cane.
Clear, dark tint, photosensitive, and prescription lenses are available.
SONAR GLASSES Technology

SONAR GLASSES technology is based on echolocation, similar to the way bats navigate in the dark. The glasses emit sound waves and measure the time to receive sound reflected by objects in your path of travel. When an object is detected, you are alerted by a subtle vibration in the temple of the glasses.
SONAR GLASSES Options
SONAR GLASSES can be fitted with prescription corrective lenses to provide a comprehensive mobility solution, supporting our customers’ specific vision requirements.
Photosensitive lenses are clear indoors and become progressively darker when exposed to sunlight. This feature enables the use of SONAR GLASSES both during the day and night without impeding visibility.
Tinted lenses can help reduce glare, improve contrast, enhance depth perception, and reduce eye fatigue in different environments.
GRAY
Provides good protection from glare and does not overly distort colors.
GRAY-GREEN
Provides higher contrast and greater visual acuity. Enhances contrast in low-light conditions.
AMBER
Provides excellent contrast because they filter some blue light, but not as much as the yellow tint.
YELLOW
Often known as blue blockers, they provide excellent depth perception and low light contrast.
BLUE
Reduce glare, help define contours, and enhance color perception.
PLUM
Allows for natural color perception while offering shade from the sun.
SONAR GLASSES are BUILT TO ORDER. We can customize:
- Lens size and color
