I am looking to purchase some prescription sunglasses. I have one pair of glasses with the magnetic clip on shades and one pair of transition lenses already. Both of these make it difficult for me to see certain things, especially in shadows. Is it possible for a different shade color to keep my eyes comfortable be still retain the ability to see detail? I can get any of several colors (including brown, grey, black, yellow and I think blue and red) and can get in light, medium or dark shading.
