some of the more expensive choices are for hi-index. only worth it for normal vision (not computer or reading only) and for prescriptions that are >-4.00 cyl or so as the higher the prescription the thicker/ heavier the lens becomes. I wouldn't go for any of the choices over $40 on your list a)not sure if the zeiss has anti-reflection coating - but if it does it may be worth the expense over the CR-39 lenses since it will cut down on reflections b)although lens thickness may not matter as you are only going to use this for your desk use, but weight may become a factor.
