A while back we at Wal-mart started selling the Nikon single vision customized. I can only assume it is the Seemax lens. I always try and research the lenses we get before I put a patient in them. I just have not had a chance to do that with this lens yet. From what I have gathered it is a double aspherical and the website for the lens also says it has 8 aspherical axes. I was wondering how that works? Is the lens going to worth the extra cost. It seems like patients with a high cyl would do well in it. Thank you for your help. The only information we tend to get is a brochure and I am not going to sell anybody anything just based on a brochure. I do however value the opinion of the optiboard.
