It is usually done without compensation and with glasses or contact lenses. Is widespread the view that the normal value of AV measured human eye subjectively is unity, although in different official certificates this value is norma tecnica agudeza visual required to pass a test of AV and indeed, it is estimated that AV 0.

As far AV human eye converge a variety of drawbacks for the practice of the art as: Specifically, the visual acuity test as performed today are not as precise than would be desirable. The standard test for measuring AV are based on the ability of identifying compounds optotypes by strokes of different contrast mainly black on white or maximum contrast.

However, it is not easy to get optotipos necessary to maintain proportionality between their lines for identification matches the AV to be determined. For example, in the E Snellen it is greater the size of the white spaces between the black lines that actually recognizes the individual to indicate which direction is the E.

Lo mismo puede decirse de otros optotipos alternativos a los indicados, como los optotipos propuestos en la patente US The same is true of alternative optotypes those indicated as optotypes proposed in US norma tecnica agudeza visual.

In the present invention optotypes 1 for measuring visual acuity characterized by the proportion of the strokes that limit the dimensions of the blanks or empty 2so that the measurement accuracy is increased proposed to eliminate arbitrariness of such spaces or disproportionation thereof relative to the dimensions of full optotype.

One aspect of the present invention relates to figures or tracings optotypes on a mesh 3 3 3 frames of equal size to norma tecnica agudeza visual other, where one of the frames is blank or empty 2 and serves to identify the orientation of the figure left or right and up or down.

The side of each frame maintains an angle of the same size horizontally and vertically, whose inverse in visual acuity minutes represents more accurately than any other standard optotype.

The size of the optotypes can be scaled to be included in any type of optometric test, and more specifically in tests measuring visual acuity far or near. One embodiment of the present invention relates to the size of the box blank 2 of optotypes having dimensions ranging from 0.

Presenting optotypes can be performed by any device conventionally used for any other set of optotypes or optotype including electronic means, on the display or projection of a computer, printed sheets, etc.

In the most common that the norma tecnica agudeza visual consists of sheets or templates in which at least one optotype print case, these may be opaque or transparent, of different sizes according to their mode of presentation and other natural or synthetic materials and preferably vitreous, cellulosic, plastic or combinations of these materials that result in a suitable substantially rigid material having a good optical quality surface.

Whatever the means used, the format of the optotipos and available for presentation essentially follow the description of the Spanish standard UNE-EN ISOso that in each presentation may include several lines of optotypes of different sizes.

Each line can include various optotypes preferably 4 oriented in different directions. Norma tecnica agudeza visual a preferred embodiment of the present invention, the color is black optotypes 1 with a white chart to cellulosic material or transparent plastic material 2.
