Introduction
Study of the vision process biomechanics is an important part of the vision care.
We acquire more than 90% of information by vision system, thus the system is
the most important for our quality of life. Physicians focus their attention on care
about the eyesight especially on infants. In this period the vision system develops
and any disturbance can affect the development process and cause a pathological
progress. The focus of our research is in measuring biomechanics of the vision
process, sensory fusion and image observation features especially in infants with
strabismus to support the diagnose and treatment. But in this text we will talk about
methods and present results in normal (health) children.

1.1.1
Anatomy and Physiology of Eye
The eye is a paired organ situated in an orbit. Front part of eyeball, the cornea, is
interface between the air outside and the aqueous humour on the inner side, which
raises its refractive index (n
1.37). The cornea's dioptric value is about 42 D.
The aqueous humour is clear colourless liquid (similar to water) with a refractive
