The Manual Lensometer is a precision optical instrument designed to measure the power, axis, cylinder, and prism of spectacle lenses. Commonly used in optical shops, optometry clinics, ophthalmology departments, eyewear manufacturing labs, and teaching institutions, this classic mechanical lensmeter provides highly accurate readings without relying on digital components.

Key Features

✔ Accurate Manual Lens Power Measurement

Measures:

• Sphere (S)

• Cylinder (C)

• Axis (A)

• Prism power

• Addition (Add) power for multifocals

Suitable for:

• Single-vision lenses

• Bifocals and multifocals

• Progressive lenses (with marking alignment)

• Contact lenses (model dependent)

✔ High-Quality Optical System

• Sharp optical reticle for clear target readings

• Smooth focusing wheel for precise adjustments

• Ensures repeatable, reliable results for all lens types

✔ Adjustable Lens Table & Lens Holder

• Holds lenses securely during measurement

• Allows vertical and horizontal adjustment

• Easy alignment for astigmatic lenses

✔ Strong & Durable Construction

• Heavy-duty metal or reinforced ABS housing

• Built for long-term daily use in busy optical environments

• Minimal maintenance required

✔ Internal Illumination (LED/Halogen)

• Bright, evenly distributed illumination

• Makes reticle and crosshair targets easy to read

• Power options vary depending on model
