ct4221 manual lensometer

The CT4221 is designed to adapt to you. Its entire assembly tilts from 0º to 90º, allowing comfortable use whether you’re standing or seated. This flexible positioning supports better posture and reduces strain during extended use, making it easy to integrate into any workflow or workstation setup. Whether you’re doing quick verifications or working through a stack of lenses, the CT4221 moves with you.

The CT4221 features bright, efficient LED illumination for clear, consistent visibility during lens readings. Unlike traditional bulb systems, the LED light source produces minimal heat, requires less maintenance, and lasts significantly longer. You get sharp target clarity without flicker or warm-up time — just reliable illumination, exam after exam.

The CT4221 is equipped with a clear, external readout system for fast, accurate lens measurements. Sphere, cylinder, and axis values are easy to read at a glance — no squinting, no guesswork. Whether you’re verifying single vision lenses or checking progressives, the crisp scale markings support precise results and a smoother workflow. It’s the kind of visibility that keeps your exams moving efficiently, with confidence in every reading.

The CT4221 comes equipped with a built-in prism compensator — standard, not optional. It allows for quick and accurate measurement of prism power without the need for add-ons or adjustments. Whether you’re checking for prescribed prism or verifying complex prescriptions, the integrated compensator ensures consistent, reliable readings right out of the box.

If you’ve used a manual lensometer before, you’ll feel right at home with the CT4221. Its classic layout and tactile controls make for an easy transition, with no learning curve to slow you down. Behind that familiar feel is precision you can trust — delivering the same accurate readings as higher-priced alternatives, without sacrificing simplicity or reliability.
