A new screening method for detecting colour vision deficiencies

Area of Science:

• Ophthalmology
• Optometry
• Medical Diagnostics

Background:

• Traditional color vision examinations often utilize the anomaloscope, which demands significant time and expertise for both administration and result interpretation.
• A need exists for a more practical, time-efficient method to assess color vision, particularly for distinguishing normal from abnormal vision in routine settings.
• The demand for such a test was highlighted at the 1973 TCU conference on color vision defects.

Purpose of the Study:

• To introduce and evaluate a new color vision testing method developed by Rodenstock.
• To provide a rapid, accurate, and practical tool for assessing color vision.
• To enable semi-skilled personnel to perform color vision tests efficiently.

Main Methods:

• Development of a novel color vision test by Rodenstock.
• The test is designed for independent use by semi-skilled personnel.
• Testing is independent of ambient light conditions and takes only 20-30 seconds.

Main Results:

• The new Rodenstock test allows for rapid classification of color vision types.
• It provides accurate results in a significantly shorter time compared to traditional methods.
• The test is user-friendly for semi-skilled operators.

Conclusions:

• The developed color vision test offers a practical and time-saving alternative to the anomaloscope.
• It effectively meets the need for a quick and accurate method for color vision screening.
• This method facilitates efficient identification of normal color vision and classification of defects.
