Description
The Hans Heiss HMR7005 is a manual phoropter designed to perform subjective refraction and binocular vision testing in optometry and ophthalmology practices.
Its integrated lens system allows the examiner to adjust spherical and cylindrical power while evaluating the patient’s refractive response. Standard spherical power ranges from +16.75 D to −19.00 D, with an extended range of +26.75 D to −29.00 D when the applicable optional lenses are used.
The instrument includes a synchronized ±0.25 D cross cylinder for refining cylinder power and axis. Its rotary prism provides measurements from 0 to 20 prism diopters, supporting binocular-balance, phoria and vergence-related procedures.
The interpupillary distance can be adjusted from 45 to 80 mm with synchronized right and left movement. An adjustable forehead rest helps position the patient consistently during the examination.

Important Notice
The HMR7005 is intended for use by qualified eye-care professionals. It does not independently determine a final prescription; results depend on the examination technique, patient responses and professional interpretation.
Confirm the mounting interface, arm compatibility, included lenses and accessories before ordering. A stand, refraction unit or examination chair is not specified as included.
