Age-Related Accumulation and Spatial Distribution of Lipofuscin in RPE of Normal Subjects


The fact that fluorescence at equal eccentricities between 2 and 7° along the horizontal meridians are higher than those along the vertical meridians (Fig. 5) could be explained if greater melanin concentrations occurred superior and inferior to the fovea. However, monochromatic fundus photographs at 570 nm,60 which delineate higher RPE melanin, are not consistent with such distribution: the area of high RPE melanin is either circular or slightly elongated horizontally. It is difficult to ascertain the role of RPE melanin at larger eccentricities: not only was the spatial resolution of ex vivo measurements of melanin38 53 too low to account for asymmetries, but information about RPE melanin along the vertical meridians is currently, to our knowledge, unavailable.

Is it just a fancy name for brown polarized lenses from VE?

My understanding of the Vision Ease Sun Melanin lens is that it has an artificial melanin which offers further protection.


Also, it is the only lens that has the Skin Cancer Foundation Seal of Approval.

It's a different color of lens from the "regular" brown polarized lens.
