Standard (EP40)
This is the most common.
Fitting the lenses with Eyepoint 40 (EP40) at the patients pupil will provide the wearer with a balanced intermediate and near viewing zone and some distance view area.
The size of the near or distant viewing area is dependant upon the frame depth (B measurement), decentration and lens shape.

3. Restricted (Blurred) distance power

6. Extended Focus
Fitting the lens at the (EF points) will provided comfortable viewing for patients that require a larger distance viewing area, a substantial intermediate and a limited near zone. EF
TACT’s ‘Extended Focus’ reference points (4mm above EP40) at the patients pupils.

Discuss with the wearer their individual indoor viewing requirements, then select the TACT application (fitting reference point) best suited to the wearers needs.

8. Simple to Prescribe – Simple to Order
Prescribe the TACT as a normal progressive lens within the range of to +6.00, add powers to (+0.25 steps).
Order the Rx power from the laboratory just as you would for a standard progressive. (Other brands of ‘computer’ lenses require that you remember that the near to intermediate differential is, order the power as something other than the standard Rx)
TACT is only available in 1.50 (CR-39) lens material.
TACT is available with Hoya’s Super HiVision AR.
