For Opticians: What Kind of Prescriptions Work with Echo Frames?

Echo Frames have been tested for +3.00 diopter to -6.00 diopter prescriptions.

For best results, keep the base curve of the prescription lenses as close to 4.25 diopters as possible.

If desired, progressive lenses may be used but the pantoscopic tilt can't be adjusted. Do not use heat.

Aspheric polycarbonate, Trivex, or high-index lenses are recommended to minimize weight.
