Buying guide
Trial frames: how to choose
A trial frame holds trial lenses in front of the patient’s eyes so the prescription can be checked in real-world viewing conditions. Comfort, PD range and lens capacity matter most, especially for children and longer examinations.
ENOCHTEC offers a series of four adjustable trial frames and the multifunction UTF-T4880 Pro.

Questions to answer before you choose
- Who will wear the frame? Children need a smaller PD range and a lighter frame.
- How many lenses do you stack? Over-refraction and complex prescriptions need more lens slots.
- Do you need monocular PD adjustment? Independent monocular PD helps with asymmetric faces.
