Note about lenses:
Biconvex lens: Distinguised by two spherical (convex) surfaces. Used
in large field, low power reading magnifiers. Magnification usually up to 4X.
Aspheric Lens: Aspheric curves allow higher magnification with less
distortion. Used by holding the more convex side (side with imprint) towards the eye.
Magnification up to 12X.
Aplanatic Lens: Consists of two equally strong plano-convex lenses. The
convex sides are arranged face-to-face. Full image is clearly defined and free of
distortion. Magnification up to 20X. (Magnification up to 4X useful for persons with
macular degeneration.)
Achromatic Lens: Top quality lens. A color-corrected lens system that
guarantees a clear, sharp image. Completely distortion free. Magnification up to 25X.
