Holds 4 Pairs of Lenses
The high quality TF-40 Trial Frame holds up to four lenses on each side.
Both left and right pupillary distances can be adjusted on the TF-40 Frame.
With the TF-40, you can ensure the best fit for an accurate trial prescription. Simply adjust the frame temple’s length by gently pulling on the adjustment part until it is in a comfortable position. Also, on the hinge of each temple, there is a frame temple angle adjustment knob that you can use to adjust the angle of the ear-hangers and ensure that the slanting angle of the trial frame is at about 15°.
Nose Pad Adjustment
With the TF-40, you can even adjust the nose pad to best suit the patient’s bridge. Adjustment knobs allow you to adjust nose pad length and angle.
The TF-40 trial frame features a soft ear rest for patient comfort.
Cylindrical and Prismatic Axis Adjustment
With the TF-40 trial frame, you can adjust the lens axis by rotating the astigmatic axis adjustment knob after the lenses are inserted.
