Chart Display VX24

Screen with dynamic polarization

Features and Benefits

• Linear polarization
• Sharpness, width, connections on the rear
• Comprehensive range of applications from low vision (ETDRS) to hyper acuity
• Screening for color vision deficiency
• Contrast Test (useful after cataract or refractive surgery)
• Working distance adjustable from 2 to 8 meters (6.5- 26 feet)
• Upgradable when new tests are added
• Multimedia feature (videos)
• New frame to better bring out the tests from the environement

Advanced analysis of the binocular function

• The use of the 3D polarization screen is one of the key features of this device allowing a perfect dissociation of the right eye/left eye. This offers the ability to proceed with many other tests with optimal quality for the exam of bi-ocular, binocular, and stereoscopic vision.

A very intuitive menu

• With an accessible duochrome calibration (for a perfect and customized extinction of your red-green filter, whatever phoropter or trial frame you use).

Optotypes

• Series of optotypes: letters, numbers, Snellen tridents, Landolt rings, 4 ranges for kids
• Large range of acuities on all tests: from 0.05 to 2.00 with many steps
• Decimal or logarithmic progression (available scores: Monoyer, decimal, LogMAR, and Snellen)
• Abililty to change the displayed letters by pushing on CHANG
• Isolated optotype, line, or triple display on the same or different acuity
• R/G test available on any test at any time
• Contrast adjustable from 100% to 5% on all ranges
