An introduction to high base curve lenses
Modern sports sunglasses often have a highly curved design. The lenses can fit tightly around the eyes and block the sun from all directions. They offer excellent protection and are very stylish.
If you need to make prescription lenses, the highly curved design is an optical challenge. The optical deformation (aberration) caused by the uneven distance from the pupil to the lens causes severe image distortion.
