How Accurate are Visual Measurements?

Due to many stresses put upon the visual system, the use of glasses and contacts, and the natural aging process, your eyes can become weak and distorted, causing blurred vision. The Rebuild Your Vision Program is designed to strengthen your eyes just as you would any other weak part of your body, improving your vision and helping you to see clearly –naturally

How accurate are visual measurements? According To Bates?

Not very. Vision changes continuously and the autorefraction and subject refraction tests performed by optometrists and opthalmologists give only a “snapshot” of your current accuity.

Autorefraction gives a sort of “at rest” measurement and subjective refraction measures your ability (some people say “under pressure to perform”) to discern what the eyes present to yourmind. A score of 20/20 does not include your acuity at the near point.

Many other measurements are not covered by a standard optometry test.

Eye-movement skills, the ability to quickly focus from one object to another.

Eye-teaming skills, converging and diverging, the ability to turn the eyes inward and outward in a coherent way.

Eye focusing skills, the ability to make rapid and accurate shifts in visual inspection with instantaneius clarity and at any distance. Also the ability to maintain focus on a an object. Focusing is about expanding the point of vision not about forcing or trying harder.

Dynamic visual acuity, the ability the see sharply while an object or person is in motion.

Peripheral vision, the ability to use side horiztonal and vetical vision. Used to position yourself in space and time. Improvements result in better balance and movement.

Binocular fusion, the ability to coordinate the eyes precisely so the brain can “fuse” the input. Dyslexia is a catch all term to label crossed and left/right reversal dificulties. It is about a lack of co-ordination between the left and right hemispheres of the brain and body. Fusion creates depth perception.

Eye-hand co-ordination. Combining the visual and motor systems, if the eye movements are jerky then the hand movements will be too. Effects sprots performance and even handwriting.

Visual form perception. Becoming aware of the dosages shapes features of sensory information. The ability to organize images on the printed page into letters and/or words.

Visualization and Visual memory. How you make and store and recall visual images and imformation. Effects you ability to learn.
