The Hess screen test was designed by Walter Rudolf Hess in 1908 with subsequent modifications.(1, 2) Hess was a famous neurophysiologist who was awarded the Nobel Prize in 1949 for his research into the functional organization of the vegetative nervous system.(3, 4) The original test used a black screen on which was marked a square-meter tangent scale. The tangent nature of the coordinate lines converts equidistant points, seen in a virtual sphere like a perimeter, into a two-dimensional chart. The test relies on color dissociation using red/green complementary filters. This maximizes the ocular deviation. A red target is illuminated or projected at the juncture where each tangent line crosses. A green light is projected by the patient and each plot is recorded. The test is repeated for the opposite eye resulting in a chart showing an inner and outer range of ocular rotation for each eye.
赫斯屏试验由沃尔特·鲁道夫·赫斯于1908年设计，随后有所改进。（1, 2）赫斯是一位著名的神经生理学家，因其对自主神经系统功能组织的研究于1949年获得诺贝尔奖。（3, 4）最初的试验使用一个黑色屏幕，上面标有一平方米的正切标度。坐标线的正切性质将在像视野计那样的虚拟球体中看到的等距点转换为二维图表。该试验依靠使用红/绿互补滤光片进行颜色分离。这可使眼位偏斜最大化。在每条正切线交叉处的交点处照亮或投射一个红色目标。患者投射出一道绿光，并记录每个标绘点。对另一只眼睛重复该试验，从而得到一张图表，显示每只眼睛眼球转动的内、外范围。
