Progressive Trial Frames TF-P, TF-PS, TF-PS4, TF-TP and TF-TPS
Trial frames for progressive lenses, so a customer can look through a progressive trial lens at distance, intermediate and near before the order goes in. Five models: three full-rim and two half-rim, each with an axis scale on every rim, a choice of PD and, on two models, memory temples.

What a progressive trial frame does
Try before you order
Fit a progressive trial lens so the customer can feel the distance zone, the corridor and the near zone before you commit to a progressive order.
Full rim or half rim
The TF-P, TF-PS and TF-PS4 hold the lenses in closed rims. The TF-TP and TF-TPS are half-rim: the lower rim is open, so nothing sits across the bottom of the lens, where the near zone is.
Axis scale on every rim
Each rim carries a 0–180° scale, so a cylinder trial lens can be set to the prescribed axis while the customer tries the progressive.
A choice of PD
Full-rim models are listed with PD options from 50 to 72, half-rim models from 58 to 66. The photographed frames carry the PD on the bridge.
Memory temples
The TF-PS and TF-TPS have memory temples, for a frame that is put on and taken off many times a day.
Four lens slots
The TF-PS4 has four slots for trial lenses, so a progressive lens can be combined with sphere, cylinder or prism lenses in the same frame.

Showing a progressive lens before the order
Why a progressive trial frame
A progressive lens changes power from top to bottom, so the wearer has to find the right part of the lens for each distance. Letting a first-time wearer try that in a trial frame, before the lenses are made, sets expectations about the narrower intermediate and near zones and the head movement they need.
Full rim or half rim
A full-rim frame holds the lens in a closed ring and can stack several lenses. A half-rim frame leaves the bottom of the lens free, so the wearer can look down into the near zone without a rim in the way.
Fit the frame like a pair of glasses
A progressive only works if it sits at the right height and distance from the eye. Use the PD that matches the customer, and adjust the nose pads and temples so the frame sits as the finished glasses will.
Check before you order
- PD: full-rim models are listed from 50 to 72, half-rim models from 58 to 66; order the PDs your customers need.
- Rim style: full rim to stack lenses, half rim to keep the lower field open.
- Temples: memory temples (TF-PS, TF-TPS) for frequent use.
- Lens fit: the trial lens size must match the progressive trial lenses you use; we confirm it on the quotation.
- Progressive trial lenses are ordered separately.
Good practice
- Measure the PD first, with a PD meter or pupilometer, and choose the frame to match.
- Set the frame level and at a normal vertex distance before inserting the lens.
- Insert the progressive trial lens with its markings in the right orientation.
- Let the customer look at distance, at a screen and at reading material, moving the head rather than the eyes.
- Note any comments about the near zone before you order.
Care
- Wipe the frame and nose pads between customers.
- Store frames flat, away from heat.

Progressive trial frame questions
What is a progressive trial frame?
A progressive trial frame is a trial frame used to show a customer a progressive lens before the glasses are made. A progressive trial lens is fitted in the frame so the wearer can try distance, intermediate and near vision. The TF-P series has three full-rim and two half-rim models.
Full rim or half rim?
Choose full rim (TF-P, TF-PS, TF-PS4) to hold the lens in a closed ring or stack several lenses. Choose half rim (TF-TP, TF-TPS) to leave the bottom of the lens open, where the near zone of a progressive lens is.
Is the PD adjustable?
The TF-PS has a fixed PD: each frame is made for one PD, chosen from 50 to 72. The other models are also listed with PD options (50–72 full rim, 58–66 half rim); we confirm how they are supplied on the quotation.
What is the TF-PS4 for?
The TF-PS4 has four slots for trial lenses, so a progressive trial lens can be combined with sphere, cylinder or prism trial lenses in one frame.
Which models have memory temples?
The TF-PS (full rim) and the TF-TPS (half rim).
Are progressive trial lenses included?
No. The frames are sold without lenses. Tell us the trial lenses you use, and we confirm the lens size and can quote progressive trial lenses with the frames.
