Requires a higher level of patient understanding and concentration compared to other visual field tests [9] Time-consuming; Learning effect: new patients improve as more tests are performed due to understanding of the test conditions. Consider the third test as the baseline result [23] Potential for artefacts (i.e. uncharacteristic vision loss ...
This method is commonly used for early detection of blind spots. The patient sits in front of an (artificial) small concave dome in a small machine with a target in the center. The chin rests on the machine and the eye that is not being tested is covered. A button is given to the patient to be used during the exam.
In photography, the circle of confusion diameter limit (CoC limit or CoC criterion) is often defined as the largest blur spot that will still be perceived by the human eye as a point, when viewed on a final image from a standard viewing distance. The CoC limit can be specified on a final image (e.g. a print) or on the original image (on film or ...

The blind spot can also be assessed via holding a small object between the practitioner and the patient. By comparing when the object disappears for the practitioner, a subject's blind spot can be identified. There are many variants of this type of exam (e.g., wiggling fingers in the visual periphery on the cardinal axes).
[27] [4] [28] [dubious – discuss] The blind spot is at about 15.5° in the outside direction (e.g. in the left visual field for the left eye). [ 29 ] The grain of a photographic mosaic has just as limited resolving power as the "grain" of the retinal mosaic .
The Worth Four Light Test, also known as the Worth's four dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision. Binocular vision involves an image being projected by each eye simultaneously into an area in space and being fused into a single image.
