The UWCDot colour vision test and low vision
Ophthalmic and Physiological Optics, 2003AbstractPurpose: Previous studies have shown that colour vision defects are common in the low vision population even when properly designed tests are used. However, there are very few clinical tests available that are suitable for this group of patients. One of the more common is the Jumbo D‐15 (JD15). Although this test uses caps more suitable for the

Journal of the Society of Dyers and Colourists, 1959
The various types and degrees of defective colour vision are discussed, leading to many different kinds of tests, which may be valuable and successful for certain purposes but less so for others. Special tests are required for dyers and colour blenders, where even a slight variation from normal colour vision is quite an important matter. The Wain test,

To the Editor: —More than 200 devices or methods for testing or measuring the color vision have been proposed, described or used. Some of these, such as after-image tests, are only of academic interest; some are very complicated, requiring elaborate apparatus and expert knowledge (luminosity curves, hue and chroma discrimination curves, etc.); some ...

KINETIC TEST FOR STEREOSCOPIC VISION
Archives of Ophthalmology, 1936In previous articles I have described two tests 1 which when positive results are obtained I believe to be the only conclusive tests for stereoscopic vision that have heretofore been brought forward. As I pointed out then, all other tests, including Hering's test with falling balls, do not eliminate the possibility of involuntary guessing.

This small, concise paperback is a remarkably comprehensive review of clinically relevant tests of vision commonly used by practicing ophthalmologists and neurologists. Frisen, an authority on visual acuity testing and perimetry, writes in a straightforward, highly readable style, and adds clinical pearls from his experience in the field that are ...

To the Editor: —I read with considerable interest your article in the August issue regarding school testing of vision. It is my belief that this is a necessary and a vital step forward. In Oregon, and I presume in the majority of states, physicians are encountering more and more difficulty with optometrists who are trying with great effort to enhance ...

Decreased visual acuity is the most common complaint in functional ophthalmic problems. Although some tests for physiologic reflexes such as optokinetic nystagmus or preferential looking can be helpful, most tests depend upon the persuasion or tricking of the patient so that they are using the bad eye when the patient believes he is using only his good
