Who created the vision charts for vision acuity?

Answer 1

it is not Vision Chart- It is called -

A Snellen chart is an eye chart used by eye care professionals and others to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Hermann Snellen who developed the chart in 1862.
The traditional Snellen chart is printed with eleven lines of block letters. The first line consists of one very large letter, an E. Subsequent rows have increasing numbers of letters that decrease in size. A patient taking the test covers one eye, and reads aloud the letters of each row, beginning at the top. The smallest row that can be read accurately indicates the patient's visual acuity in that eye.

The symbols on an acuity chart are formally known as "optotypes." In the case of the traditional Snellen chart, the optotypes have the appearance of block letters, and are intended to be seen and read as letters. They are not, however, letters from any ordinary typographer's font. They have a particular, simple geometry in which:

the thickness of the lines equals the thickness of the white spaces between lines and the thickness of the gap in the letter "C"
the height and width of the optotype (letter) is five times the thickness of the line-.

Answer 2

Hermann Snellen (1834-1908)
Snellen's chart: The familiar eye chart used to measure how well you see at various distances.

Snellen's chart is imprinted with block letters that line-by-line decrease in size, corresponding to the distance at which that line of letters is normally visible.

The letters on Snellen's chart are, not surprisingly, called Snellen's test type. Each block letter is quite scientific in design (so that at the appropriate distance the letter subtends a visual angle of 5 degrees and each component part subtends an angle of 1 minute).

The chart and the letters are named for a 19th-century Dutch ophthalmologist Hermann Snellen (1834-1908) who came up with them as a test of visual acuity. Visual acuity refers to the clarity or clearness of the vision, a measure of how well a person sees. The word "acuity" comes from the Latin "acuitas" = sharpness

Answer 3

Improving your vision by reversing the deterioration process is perhaps a remote possibility but it may well include a lot of wishful thinking. Probably a bit like trying to reverse the ageing process. You can certainly slow it down a bit but reversing it is still out of reach. If eye problems are due to some temporary defect such as eye strain then, of course, the defect can be overcome You can certainly slow down the sight deterioration process with a good diet that includes antioxidants. These can be found in fruits and vegies that are coloured a bright orange, yellow, red and purple and they include carrots, pumkin, oranges, melons, tomatoes, strawberries, blueberries, bilberries, purple grapes, beetroot, red cabbage, etc. Health supplements from a health store may also help in this regard and one such product is called "Vision Defence Formula" and is based on bilberry and also contains lutein, beta carotene, Vitamin B2, zinc, Vitamin C and some other components. A Yahoo search for bilberry + eyesight may be of interest to you.
