Precision and convenience are a tradition in high quality TOPCON optical instruments. The VT-10 vision tester advances this tradition still further, making refraction quicker and easier than ever before, providing unequaled performance and exceptional versatility. Precision in design and workmanship guarantees accuracy in refraction measurements-accuracy that won't deteriorate even after long years of use. Total quality from TOPCON means you can have total confidence in the performance you'll enjoy from the VT-10 vision tester.

Type:	Subjective refraction testing equipment
Item and range of measurement:	The value in ( ) is with accessory lens or auxiliary lens attached:
Myopia:	0 to –19.00D in 0.25D step (0.12D step)
Hyperopia:	0 to +16.75D in 0.25D step (0.12D step)
Astigmatism:	0 to –6.00D (-8.00D) in 0.25D step (0.12D step)
Cross-Cylinder:	± 0.25D (± 0.37D and ± 0.50D as option)
Phoria and vergency:	20 to 0 to 20 by 1 step Inner 40 Outer 40 (50) Upward and downward 40 (46 )
Near vision test:	Main optical axes of both lenses converges by means of a tilt mechanism at 40 cm in front of the eyes at 64mm P.D. If P.D. for far vision is less than 54 mm, converging operation stops.
Binocular balance test:	Rotary prism and polarizing lens methods are available.
P.D.:	48 to 75mm by 1mm step
Level adjustment:	More than 4.5° for right and left banks
Dimensions:	335 (at 64mm P.D. setting) x97 x 294mm
Weight:	4.5kg
