| Product Name | UniSys Professional Visual Refraction System |
| Product Overview | UniSys is a professional digital visual refraction system designed for precise refraction, astigmatic correction, contrast sensitivity testing, red-green duochrome testing, stereo testing, colour vision testing, and functional binocular vision assessment. It provides software-based optotype display with multiple test modes, Indian language options, ETDRS support, and remote-controlled operation for modern refraction clinics. |
| Product Brief Detail | The UniSys system combines multiple refraction and vision testing functions into a digital chart platform. It supports standard optotypes, ETDRS display, contrast sensitivity variation, cylindrical correction tests, randomised optotype display, stereo tests using red-green goggles, colour vision tests, and functional tests such as Worth 4 Dot, Schober, and phoria testing. The system is suitable for compact refraction rooms because the viewing distance can be set from 3 ft to 25 ft in 1-inch increments. |
| Category | Digital Refraction System / Computerised Vision Chart System |
| Main Use | Subjective refraction, astigmatic correction, contrast sensitivity testing, visual acuity testing, duochrome testing, binocular vision screening, stereo testing, and colour vision testing |
| Astigmatic Correction | Supports astigmatic / cylindrical correction from 1° to 180° in 1° increments. Helps determine cylindrical axis and power accurately. |
| Contrast Sensitivity | Provides contrast sensitivity variations of 50%, 25%, 12.5%, and 6.25%. Useful for detecting reduced visual performance related to cataract, glaucoma, retinal, or ocular defects. |
| Red-Green Duochrome Test | Used for final spherical correction to avoid over-correction or under-correction. Available from 6/6 to 6/60 and supported across optotype display modes and ETDRS. |
| Refraction Distance | Adjustable from 3 ft to 25 ft in 1-inch increments, allowing installation in small refraction rooms. |
| Optotypes / Test Symbols | English alphabets, numbers, alphanumeric, tumbling E, Landolt C, dots, HOVT, Allen symbols, geometric shapes, pediatric numbers, clock symbols, images, and Indian language optotypes. |
| ETDRS Support | ETDRS chart can be displayed using any optotype or language, according to the brochure. |
| Indian Language Support | Includes multiple Indian languages such as Hindi, Tamil, Kannada, Gujarati, Bengali, Punjabi, Telugu, and Urdu. |
| Display Modes | 1-line, 1-alphabet, 3-line display, randomised optotype display, mirror mode, and white-on-black display option. |
| Randomisation | Software-generated random optotype display helps prevent memorisation and improves test reliability. |
| Stereo Test | Includes stereo testing for 3D depth perception using red-green goggles. |
| Colour Vision Test | Includes colour vision test display. |
| Functional Tests | Includes functional binocular vision tests such as Worth 4 Dot, Schober test, and phoria-related tests. |
| USB Image Support | Includes USB image support; brochure mentions 16 GB USB for surgical videos and images, patient education clips, and cartoon movie display for pediatric patients. |
| Remote Control | Supplied with remote operation. The brochure highlights twin remote mode, allowing two UniSys systems to be placed near each other without remote interference. |
| Monitor Options Mentioned | Brochure mentions multiple display options: 15” VGA, 19” VGA, and 22” HDMI. |
| Software Based System | Embedded software-based refraction system with upgradeable software support. |
| Service Support Feature | Brochure mentions a piggy-back module service concept where the customer can replace the defective module and return it in the same shipping package. |
| Target Users | Optometrists, ophthalmologists, refraction clinics, optical stores, hospitals, vision screening centres, and pediatric eye-care practices |
| Key Advantage | Combines refraction chart, astigmatic correction, contrast sensitivity, duochrome, stereo, colour vision, functional tests, Indian languages, and pediatric optotypes in one system. |
