Q: What are the disadvantages of using aspheric lenses?
A: Aspheric lenses have some limitations, including a relatively smaller light area, potentially causing slight blurring of objects viewed through the lens’s edge when the eye rotates. Additionally, due to the natural spherical shape of the eyeball, wearers may need time to adapt as objects viewed through aspheric lenses may appear protruding when the eye rotates towards the edge.
