Simple and Inexpensive Design for a Colour Vision Test Cabinet

— The intensity and colour content of daylight varies as a result of diurnal changes as well as differences in weather and seasons. Colour tests recommended to be performed under daylight conditions would have poor repeatability if conducted under such varying daylight conditions. Therefore, it is necessary for colour tests to be conducted under standard conditions in all subjects. In the present paper we have established a method for designing a colour vision test cabinet that facilitates colour testing under the constant conditions and standard requirements. In addition, we compare the Farnsworth-Munsell 100-Hue Test obtained under our conditions with the normative data in the literature.
