The frameless - rimless prescription glasses that are round shaped use are SILHOUETTE "TMA The Must Collection"; the temples and bridge are Titianium.

In regard to the lenses: I have seen photos Roger Daltrey wearing Silhouettes with light blue tinted lens that are of the old Bausch & Lomb "Ray Ban" round shape. SILHOUETTE does not offer that "form" (lens shape) for the U.S. The other lens shape is slightly more oval than round & appears to be 5 - 7 mm larger.

In regards to lens brand & material: more than likely the lens are "progressives". This multifocal lens that has normal distance in the upper half. Just below the pupil is a channel for intermediary distance (computer), that goes down into an area that is 18 - 25mm wide for the reading power.

I wear SILHOUETTES & Varilux "Physio 360" progressives because they are so light weight, @ 1/3 the weight of other RX eye-wear. They offer all day comfort unlike other eye-wear.
