Which lens treatment is effective in reducing edge thickness for high minus lenses?

Choosing edge polish as the lens treatment effective in reducing edge thickness for high minus lenses is based on the specific optical properties and aesthetics of these lenses. High minus lenses, which are prescribed for myopia, often have significant thickness at the edges because light is bent inward to compensate for the refractive error.

Applying an edge polish can help create a smoother transition from the thicker edge to the center of the lens, giving the appearance of a thinner lens overall. This treatment can enhance the cosmetic appeal by creating a more finished and refined look, which is particularly important for patients who may be concerned about the visual bulk of their lenses.

By contrast, treatments like scratch coating or anti-reflective coating mainly focus on enhancing the durability and visual clarity of lenses rather than altering the physical dimensions or thickness. Similarly, UV coating protects against harmful ultraviolet rays but does not affect edge thickness. Therefore, edge polish directly addresses the concern of visual bulk by refining the edges, making it the most effective option for high minus lenses.
