I have been wearing glasses for a few years now...contacts are not possible. The last time I went for glasses, I thought progessive types for protection from the sun was a great idea and I was not as much of an outdoor photography nut. Whenever I go outside, the lens turn dark to shade my eyes, great for protection, terrible for photography. Today was the day the straw broke the camels back. The sun came out and reflected off the snow, I could not look through the viewfinder and see very well. I could not even tell how the photos or the scenes were. This week I will now have to go for new glasses. I will just have to bring sunglasses with me for those sunny days. Look at my avatar - and that was not a sunny day.
