These units attach and lock onto the tops of over 20 long eye-relief Tele Vue eyepieces to achieve the sharpest full-field viewing possible. DIOPTRX™ models are available in ¼ to 3½ diopter (¼ steps from ¼ to 2½ diopters, then ½ diopter steps to 3½-diopters), and are rotatable for tuning to the best orientation. A series of engraved letters on the barrel helps to monitor orientation. Simply choose the DIOPTRX™ model that matches your eyeglass prescription for astigmatism. All lenses are multi-coated glass in anodized aluminum housings with rubber eyeguards.\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eYou're more likely to see a sharper, higher contrast image, because:\n\u003cul\u003e\n\u003cli\u003eThe Dioptrx is always completely aligned to the eyepiece optics, eliminating aberrations from a decentered mismatch of eyeglass power and astigmatic axis.\u003c\/li\u003e\n\u003cli\u003eDioptrx can be rotated to exactly compensate for the astigmatic axis angle in real time, since both head angle and age can vary your eyesight astigmatic angle.\u003c\/li\u003e\n\u003cli\u003eDioptrx likely has better multi-coatings than eyeglasses, and certainly is better in transmission and reflection reduction than uncoated eyeglass.\u003c\/li\u003e\n\u003cli\u003eDioptrx is more likely to be cleaner than eyeglasses, which may have scratches and smudges from constant use and wear and tear.\u003c\/li\u003e\n\u003cli\u003eDioptrx allows seeing your normal maximum contrast that eyeglasses can diminish (remove your eyeglasses and see how contrast improves in normal vision).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eYou're more likely to see the full field in 100° Ethos eyepieces because your eyeglasses are more limiting in \"effective eye-relief\".\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch4\u003eHow to Choose DIOPTRX™ Models\u003c\/h4\u003e\n\u003cp\u003eYour prescription may look like this, with different numbers.\u003c\/p\u003e\n\u003ctable cellpadding=\"4\" cellspacing=\"0\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"20%\" align=\"right\"\u003e\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"caption_gray\"\u003eSPHERICAL\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003eCYLINDER\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"caption_gray\"\u003eAXIS\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"20%\" align=\"right\"\u003eRight Eye\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"caption_gray\"\u003eO.D.\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"caption_gray\"\u003e+1.50\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e-0.50\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"#caption_gray\"\u003e45\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"20%\" align=\"right\"\u003eLeft Eye\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"caption_gray\"\u003eO.S.\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"caption_gray\"\u003e-0.50\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e+1.50\u003c\/td\u003e\n\u003ctd width=\"20%\" align=\"center\"\u003e\u003cspan id=\"caption_gray\"\u003e135\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eSimply choose DIOPTRX™ to match the cylinder (astigmatism)  value of your preferred viewing eye.
