    Any Eyediya ?

    Cornea isnt AR coated but it beats in performance to any and every AR Lens. If that is so, cannt we dream to have a Hard Coat lens without AR but Cornea Quality ? What makes the light reflect back on atomic level ?

    Oops! I think you dropped something.

    You forget the intention of AR coatings - to prevent glare caused by the eyeglass lens itself. The healthy cornea without an eyeglass or CL to contend with most certainly will outperform the circumstance that requires such a device.

    AR is meant to reduce light reflectance of devices used such that only reflection at the corneal level is present.
