What might be a consequence of achieving good cosmetics in lens design?

Achieving good cosmetics in lens design often refers to the aesthetic aspect of the lenses, ensuring they look visually appealing. However, this cosmetic focus can sometimes lead to compromises in other essential optical properties. One significant consequence can be compromised peripheral vision.

When a lens is designed to prioritize aesthetics, it might involve utilizing materials or shapes that enhance the visual appearance but do not adequately account for the optical performance of the lens at its edges. This can create distortions or a reduction in clarity in the peripheral areas of vision, negatively affecting how a person perceives objects outside of their direct line of sight. Therefore, while the lens may look good, its functionality—particularly in terms of peripheral vision—might suffer as a result.
