After years of struggling with glare and squinting I decided to go get myself a pair of transition lenses.  A few friends had them and loved them.  These lenses change to accommodate the amount of light that is in the room.  When I walk outside into bright sun light they turn into the perfect pair of sun glasses and I can see clearly and without having to squint.  I have struggled for years with a sensitivity to light and these lenses have become a life saver.  When I am driving I see well and have no problems with the sun.
