Presentation transcript:

Limited (Clear) distance Wide comfortable intermediate EP40 Standard Viewing (EP40) Features Limited (Clear) distance Wide comfortable intermediate Wide (Clear) near The Hoyalux TACT has three fitting options (Eyepoints) which optimize the positioning of the lens to best meet the wearers viewing requirements.

Standard (EP40) This is the most common. The effective power at EP40 is 40% of the total addition power. 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.

Restricted (Blurred) distance power Emphasis On Near Viewing (EP60) Features Restricted (Blurred) distance power Widest intermediate Widest near

Emphasis on near and intermediate. EP60 For EP60 the effective power at the fitting point is 60% of the add power. Emphasis on near and intermediate. Fitting the lenses with Eyepoint 60 (EP60) at the patients pupil will provide the wearer with more concentrated near viewing and a substantial intermediate zone. Depending on the frame size, decentration and lens shape, a limited portion of distance power may also be present. (Refer to TACT layout guide)

Extended Viewing (Indoor) Features Functional (Clear) distance Wide intermediate Limited (Blurred) near EF

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.

Fitting Reference Points Standard (EP40) Limited (Clear) distance, Wide intermediate, Wide (Clear) near Near (EP60) Restricted (Blurred) distance, Widest intermediate, Widest near Extended (EF) Functional (Clear) distance, Wide intermediate, Limited (Blurred) near Discuss with the wearer their individual indoor viewing requirements, then select the TACT application (fitting reference point) best suited to the wearers needs.

Simple to Prescribe – Simple to Order Prescribe the TACT as a normal progressive lens within the range of -8.00 to +6.00, add powers +1.00 to +3.00 (+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.
