Access provides wide areas of clear vision at near and intermediate ranges. It s the first near vision lens to offer wide, clear viewing from reading distance up to seven feet away. Access makes an ideal second pair for computer users. Other beneficial uses of Access are as reading or indoor glasses for presbyopes who normally wear single vision readers or contact lenses, or for anyone who needs a near correction. Through a unique application of aspheric technology, Access provides wide, clear near viewing in the lower half of the lens and mid-range vision in the upper half.
Vision flows smoothly from near to mid-range.
The lower half of the lens contains the near Rx. No fitting height need be specified when dispensing Access because the lenses can be edged to frame center. We recommend that Access not be used in frames with a B height of less than 30 mm, because the patient will not get the full benefit of both near and mid-range vision. Access has a power that varies from the near Rx to a mid-range Rx, and so patients may see blur if they use the wrong power for the object being viewed. In addition, all variable power lenses have some surface aberrations, but in Access these are at very low levels.
