Details

The Burton BR8500 is designed for a relaxed refraction process. Spherical power ranges from -19.00D to +16.75D in 0.25D steps (-29.00DS to +26.75DS and ±0.12D steps with auxiliary lens). Cylindrical power ranges from 0 to -6.00D in 0.25D steps (0 to -8.00D with auxiliary lens). All the lenses are coated in high-grade plated film to eliminate any glare or ghost images. Precision excellence in refraction Cross cylinder and rotary prism Employs a state-of-the-art convergence system Greater testing range with the use of auxiliary lenses Free spinning bearings provide greater precision and durability Visual functions area available (binocular vision, stereopsis)
