   Colour sensitivity test - to assess the function of the Optic nerve; Contrast sensitivity test - to assess the function of rods photoreceptors; Visual field test - to know the extent of the individual's field that is sensitive; Near visual acuity - to assess the reading ability at near

3. Humphrey visual field analyser - Wikipedia

   en.wikipedia.org/wiki/Humphrey_Visual_Field_Analyser

   It is expressed as a percentage of visual function; with 100% being a perfect age-adjusted visual field and 0% represents a perimetrically blind field. The pattern deviation probability plot (or total deviation probability plot when MD is worse than -20 dB) is used to identify abnormal points and age corrected sensitivity at each point is ...

   en.wikipedia.org/wiki/Lea_test

   The "LEA Numbers Test" was the second of the LEA tests that was developed and can be used to test the visual acuity of older children and even adults. This test has a layout similar to a typical Snellen chart, with lines of numbers decreasing in size towards the bottom of the page. Like the optotypes of the LEA Symbols Test, these numbers are ...

5. Visual field test - Wikipedia

   en.wikipedia.org/wiki/Visual_field_test

   Perimetry or campimetry is one way to systematically test the visual field. [1] [failed verification] It is the systematic measurement of differential light sensitivity in the visual field by the detection of the presence of test targets on a defined background. Perimetry more carefully maps and quantifies the visual field, especially at the ...

   Confrontation visual field testing is an important part of a routine ophthalmological or neurological examination. It can be used for rapid and gross assessment of large-scale visual field problems due to ophthalmological or neurological diseases, such as homonymous and heteronymous hemianopias, quadranopsia, altitudinal visual loss, central/centrocecal scotoma etc. [1] [2] Test using a red ...

   The Jaeger chart is an eye chart used in testing near visual acuity.It is a card on which paragraphs of text are printed, with the text sizes increasing from 0.37 mm to 2.5 mm. [1] This card is to be held by a patient at a fixed distance from the eye dependent on the J size being read.

9. Microperimetry - Wikipedia

   en.wikipedia.org/wiki/Microperimetry

   Microperimetry, sometimes called fundus-controlled perimetry, [1] is a type of visual field test [2] which uses one of several technologies to create a "retinal sensitivity map" of the quantity of light perceived in specific parts of the retina [3] in people who have lost the ability to fixate on an object or light source.
