I thought it would be fun to paint some cool looking eyes on my specs. Unfortunately, now I bump into walls.

PS - If you want to know, this resulted during my attempts to lighten the sun-darkened tint of my glasses. I selected and copied to a new layer the lenses and set blending mode to screen -- generally an easy and effective way to lighten things up. You can do this multiple times if necessary. Three is too many in this case -- gave the interesting results shown here. :)
