Our assorted reader packages come with some low, medium and high powers. The quantity per power is based on research and our experience in the field. For mission and outreach trips, a 300 or 500 assorted reader package is usually sufficient. If you will be seeing post-cataract or older patients, you can order more high power glasses. Or if you will be seeing more young adults, you can order more low powers. We also offer supplemental reader packages for those serving primarily older or younger populations.
