You may have seen ads that look like this:
17.5mm? That wouldn't hardly fit in your eye!
Don't be fooled by such simple marketing techniques. Don't use just any supplier's photos as a guide, instead use the photos of the lens in an actual person's eye as your guide. This way you'll see what your lenses will actually look like, not how some suppliers want you to see them!
