An eyeglass apparatus having a variable focal length lens and an associated method for varying the focal length of the lens uses a lens having a focal length which is variable as pressure along the lens is varied. Focal length adjusting mechanisms carried by the eyeglass frames provide for manual or automatic adjustment of the lens focal length.
