Guaranteed Fit Plan
(90 Days)

If for any reason the original pair does not work, they may be exchanged or returned for a FULL CREDIT within 90 days. After the return of the original pair, any lenses ordered then returned for either credit or cancellation will be assessed $8 material recovery fee per lens. There is no charge for adjustments during the 90 day warranty period.

Ultima Refinements
We have found the following adjustments to be meaningful in ascertaining optimum fit  and visual acuity.

  1. If near vision is good but distance is not acceptable, increase distance Optical Zone. Add +.25 to +.50 to add power.
  2. Lens lag on blink (lens must center): Increase total diameter.
  3. Add needs +1.00 more: Decrease distance Optical Zone. Use same specs.
  4. Add needs +.50: Increase add power +.50. Use same specs.
  5. Allow minimum 30 minutes adaptation time.
  6. Over refraction should be done with trial frame to eliminate pupil dilation behind phoropter.
  7. Determine pupil size in normal light: small, medium or large. 4.0 being average.

Ultima Multifocal Fitting Tips

  1. Fit as single vision to determine effective add power, add +.50 to spectacle Rx.
  2. Trial fitting is highly suggested for a higher degree of success and greatly reduced chair time.
  3. When fitting, allow minimum of 30 minutes adaptation time. Over-refraction should be done with handheld lenses, do not use a phoropter for this test because of pupil dilation in low light.
  4. Take note of eye dominance, pupil size and lid positioning in normal light.

Premier Asphere Multifocal Fitting Guide

Our Lens Design
The Premier Asphere is a posterior surface multifocal developed for presbyopes with an add power of up to +2.50. The aspheric back surface parallels the natural corneal eccentricity which produces a better centering and more comfortable fit for the patient. The crisp optics of the Premier Asphere give the patient the distance, midpoint and near vision they have been demanding.

Benefits of the Premier Asphere:
  • Easy adaptation
  • Immediate binocularity
  • Excellent intermediate vision
  • Fit empirically with 100% warranty
  • Loaner trial sets available
  • Mad in FluoroPerm 60 (any color)
