TRIAL FRAME

Main Technical Index:
*Adjustment of Pupillary Distance: Two eyes’ pupillary distance is 54 mm~70 mm, and adjustment of each grade requires change of 2 mm.
*Axis graduation of calibrated dial: Left and right calibrated dials are identical, where axis graduation line runs clockwise along axis graduation line of lens frame, 165°, ~0°, ~180° and ~25°, with distance of graduation line being 5°
*Inner pore diameter of lens frame: ф 34 mm
*Number of lens that can be inserted into left and right lens frames at the same time: 4 pieces
*Degree that lens rotates around optic axle inside lens frame: 360°
*Non-parallelism between lens optic axis line and geometric centre-line of lens frame: ≤2.5°
*Misalignment between lens optic center and geometric center of lens frame: ≤0.5 mm *Displacement of lens to position of geometric center of lens frame: ≤0.3 mm
*Adjustment range of nose rest: ---Up and down direction 4 mm ---Width between 2 nose rests 7.5 mm~11 mm ---Rotation angle of left or right nose rest 20°
*Length adjustment range of left or right lens frame leg: 90 mm~120 mm
*Maximum distance between left and right lens frame legs: 200 mm
