Description
Trial Frame TF-3
The Trial Frame TF-3 is a practical ophthalmic trial frame designed for professional refraction procedures in optical stores, optometry practices, and vision care settings. Its adjustable structure supports patient comfort and precise lens positioning during visual examinations.
The frame offers a PD adjustment range of 48 ~ 80 mm, allowing it to adapt to different patient needs. It also provides an axis step of 5°, supporting accurate alignment during refraction testing.
The arm temple length can be adjusted from 78 ~ 108.5 mm, while the arm temple tilting range is 25° / 10° for up and down positioning. This helps improve fit and stability during examinations.
For lens placement, the TF-3 includes 3 front lens slots and 2 back lens slots. It is compatible with trial lenses measuring 38mm in diameter, and the front lens offers a 360° rotation range for flexible lens positioning.
The vertex distance range is adjustable from 4 ~ 14 mm, supporting better control of lens-to-eye positioning. With a lightweight design of only 60g, the Trial Frame TF-3 is suitable for routine clinical use and extended refraction sessions.
