Progressives contact lenses.

As an alternative to the Table, the following simple calculations can be

made:

Initial Lens Power = Vertex corrected spherical equivalent +

½ (Spectacle Add Power)

Note: If either plane of the spherocylindrical spectacle Rx is greater

than ± 4.00D, a vertex distance correction is necessary to determine the

lens distance power required at the corneal plane (see Vertex Distance

Conversion Chart in the back of this booklet).

Example 1: Spectacle Rx: +4.50 -0.50 x 090 Add +1.00

Spherical equivalent: +4.25 D

Vertex corrected Rx: +4.50 D

Initial trial lens: +4.50 + (1.00/2) = +5.00 D

Toric: -4.50 -0.75 x 180

Example 2: Spectacle Rx: -6.00 -1.00 x 090 Add +2.00

Spherical equivalent: -6.50 D

Vertex corrected Rx: -6.00 D

Initial trial lens: -6.00 + (2.00/2) = -5.00 D

B. Lens Fit Assessment

FOCUS

DAILIES

Progressives contact lenses should be comfortable

immediately upon placement on the eye. Care should be taken to ensure

the lens is free of foreign particles such as lint, and is not inverted prior to

placement on the eye. Reex tearing due to an uncomfortable lens may

cause the lens to stop moving and give the appearance of a tight t.

Allow the lenses to settle on the eyes for approximately 5 to 10 minutes.

This allows time for the patient to adapt to the lenses and time for the lens to

equilibrate.
