Magnifying Eyeglasses for crafts

Aspheric lenses: on the other hand, deviate from this uniform curvature, adopting a non-spherical curvature. There is a more gradual transition from the centre to the periphery, this variation from sphericity is often too small to be detected by the eye. This design allows for better control over aberrations and image quality, resulting in improved clarity and sharpness of vision.

The key to the superiority of aspheric lenses lies in their complex design. Instead of having a single radius of curvature, these lenses exhibit a varying curvature across their surface, meticulously calculated to counteract aberrations. This design enables aspheric lenses to focus light rays more precisely onto a single point, enhancing image quality across the entire visual field.

Traditional lenses: called spherical lenses, possess a uniform curvature across their surface, which often results in certain optical aberrations like distortion and blurring, especially toward the edges of the lens.
