With our vast experience and technical know-how in the ophthalmic field we have developed a more precise and labor saving tester. The GR-14 Refractor is applicable to ophthalmic departments and optical stores for precision measurement of visual functions such as myopia, hyperopia, astigmatism, visual acuity balance, phoria, stereoscopic vision and visual acuity.
Level adjustment
Corneal Aligning Device
Level adjustment can be made easily, one-touch operation by using the leveling knob and level.
It is used to align the corneal vertex of the patient and set the patient´s cornea in the correct position (at 12mm from the view tester lenses). Measurement should be made at the “0” position of the scale.
Outstanding features · Atractive design. · Precision excellence in testing for myopia and astigmatism. · Cross cylinder and rotary prism provide the widdest field of view. · It employs an unique mechanism in the convergence system. · The selection of auxiliary lenses provide a greater testing range. · Oil less bearings provide greater precision and durability. · Other visual functions are available, such as binocular vision (binocular vision, stereopsis, aniseiconia, etc.). · High-grade coating excecuted on all lens surfaces.
Convergence System
Rotary Prism
Exact adjustment can be made from -19.00D to +16.75D in 0.25D steps. The sphere power rapid feed dial allows rapid eye examination per ±3.00D. With accesory lenses, it is possible to read op to ±0.12D. Also the auxiliary lenses ±10.00D (optional) are available to extend adjustment range up to -29.00D ~ +26.75D.
The readings can be taken accurately at 20Δ in 1Δ scale graduation. It has also a click stop that permits you to measure horizontal and vertical strabismus and heterophoria. Using both right and left prism it is possible to take readings up to 40Δ and test eye balance.
Adjusted Cylinder Power and Axis The cylinder lens graduated in 0.25D steps allows adjustments up to 0~6.00D and with the accessory lens -2.00D, it is possible to extend adjustment range up to -8.00D. The cylinder axis can be adjusted up to 0º~180º in 50 steps. Each adjustment can be made rapidly with two knobs on the same axis.
Cross Cylinder (±0.25) The cross cylinder loupe rotates automatically through a special syncronized mechanism with the control knob, to change the cylinder lens axis.
Precise measurement is possible with the lens set at a suitable angle for near vision testing (by closing the convergence lever inward) as well as for distance (by opening it outward). This converges the optical system coincident to the convergence of the patient´s eye while the patient looks througth the correct optical centers. Therefore, this unique system ensures perfect testing.
Adjusting Sphere Power Readings
Near Point Scale and Chart The scale can be graduated in “Inches”, “Centimetres” and “Diopters”. It can be set at a distance you like to use and when it is not in uso, it can be stored in a standing position. The Near Point Chart contains a rotable disc with 12 kinds of tests on both sides. The scale is 67cm/26.4 in length.
Accessory Lenses Three types of spare lens are included: -2.00CYL, -0.12CYL and 0.0CYL
