What color vision tests do we use in VR?

• A. jumbo D-15, isihara at closer working distance (isihara plates and HRR have large numbers/symbols)
• B. Ishihara plates at standard distance
• C. Farnsworth D-15 test
• D. Anomaloscope testing only

Answer: (A)

In vision rehabilitation practice, tests need to be easy to see and perform for people with reduced vision or who must work at near distances. Using large-format, high-visibility color plates makes the assessment reliable for these clients. The jumbo D-15 test provides oversized color discs arranged in a sequence, so color ordering can be checked even when acuity is limited. Pairing that with Ishihara plates at a closer working distance takes advantage of the well-known red–green screening plates while ensuring the symbols are large enough to discern; HRR plates can also be used in a similar large-symbol, near-distance format. Together, these near-distance, large-stimulus tests give a practical, accessible color-vision screen in rehabilitation settings. More specialized tools like an anomaloscope offer precise color-matching information but aren’t typically used for routine screening in VR settings, and the Farnsworth D-15, while useful, is often less accessible to individuals with low vision unless presented in a larger, near format.
