For those looking for a photocromic lens but have a smaller face size the Oakley Bottlecap with Transition Lens is an ideal choice. The innovative photocromic lens darkens as you approach bright light and lightens as you approach shaded or overcast areas. The contour wrap provides a welcome alternative to the wide corners of traditional sunglass frames providing a better fit match for narrower or smaller facial sizes yet comfortable for larger faces too.
