AI Technical Summary
Existing underwater vision systems, such as swimming and diving goggles, suffer from significant visual distortions due to the difference in refractive indices between air and water, particularly causing image dilation and horizontal expansion, which affects clarity and peripheral vision.
The goggles feature lenses with varying thickness and curvature, including a cylindrical front vision part with 2.0 mm to 4.0 mm thickness variation and a lateral spherical vision part with 2.5 mm to 5.0 mm thickness variation, combined with cylindrical and spherical curvatures on horizontal and vertical axes to minimize distortions.
The solution provides virtually undistorted panoramic vision of approximately 170°, reducing horizontal distortions and enhancing clarity and focus while maintaining a wide field of view, with minimal hydrodynamic drag and improved stability.
