>but bottom was like looking though coke bottles. Yes, exactly! Many others have the same issues and describe it in similar ways: "tunnel vision", or "looking through a pinhole" It's very strange that optometrists & opticians don't explicitly explain this trade-off upfront: the "convenience" of progressive bifocals and the "fashion" of hi-index lenses will always be blurrier away from the center point than single vision lenses. If customers were properly educated ahead of time by the opticians, they wouldn't think progressives and hi-index were "defective". The lenses are not defective -- it's actually an unavoidable optical tradeoff! Your eyes just happen to be sensitive to it. Some people adjust to progressives or high-index lenses just fine. Others don't. I tried them for 3 weeks as they recommended and never got used to them.
