Hi there. I am about to order contact lenses online. I cannot call my optician to ask this question as they would insist I buy my contacts from them, which I did for the first sets, but they are expensive through them. I have 2 sets of contacts, one for near vision and one for far vision, depending on what I am doing: computer work or recreation. The box for the right eye of the near vision contacts shows an axis of 160, however the box for the far vision contacts shows an axis of 150. What is the difference? Is it a matter of fit? Will it affect the prescription if I request a 160 axis for both sets of right eye contacts? Thanks for you help :-) Eleanor
