Bifocals
The gradual decrease in ability of the eye to focus is a natural
part of the aging process. Bifocals contain two prescriptions for
correcting vision at different distances. Bifocals aid both the
near and far vision, with a visual line dividing the two distinct
areas of prescription.
Multifocal lenses are designed to correct near and distant vision
for presbyopia. Lens segments vary in width and placement to meet
specific requirements.
Trifocals
Trifocals are prescribed to aid near, far and middle distance vision.
The trifocal lens design has three distinct areas of power to be
used, with visible lines dividing the three distinct areas of prescription.
Multifocal lenses are designed to enhance distance, near and mid-range
vision. Lens segments vary in width and placement to meet specific
requirements.
Blended Multifocals
These lenses have two focal corrections without the noticeable lines.
The area that fuses the two powers together is an unusable area.
Smart Seg Flat Top
These lenses change power gradually as the eye moves down through
the near segment allowing a range of ten feet. One visible line
divides the distant power prescription to the intermediate and near
prescription.
