Overcasters™ are lightweight, clip-on visors that attach to any prescription eyeglass or sunglass frame in seconds, flip up instantly for the perfect instrument-to-visual transition, and when flipped down create a near perfect "simulated instrument" condition.
Overcasters™ clip into any Airport/Facility Directory, Flight Guide™ or approach binder for easy storage, and can be attached and in use in seconds. Their dark plastic lenses make "cheating" difficult in the cockpit, and are manufactured for flexibility and durability. And perhaps best of all, Overcasters™ are widely accepted by FAA examiners for use in practical tests and checkrides.
Excellent view limiting choice

I had been using Jepp Shades for all of my IFR recurrency work, but always had to take them off in order to put sun glasses on. The ASA overcasters clip to the sun glasses, and they solved my problem. Although they may feel a bit flimsey at first, the flexing actually has a good purpose. You can push them out of the way in order to see a specific area of the sky when you are looking for traffic. They are very easy to clip on just before doing an approach. I think they are a good IFR view limiting device choice.
