The corpus ciliare is also known as the ciliary body or ray body and is located in the medial eye membrane. It serves accommodation, aqueous humor production, and lens suspension. If the suspension fibers of the lens break in an accident, the lens may slip out of the clamping of the ciliary body in a … Corpus Ciliare: Structure, Function & Diseases
The term convergence comes from the Latin word “convergere” and means “to incline toward each other,” “to lean toward.” Convergence is the position of the eyes at which the lines of sight intersect immediately in front of the eyes. What is convergence? Convergence is the position of the eyes with which the lines of sight … Convergence: Function, Tasks, Role & Diseases
The convergence reaction is the reflexive constriction of the pupils during convergence, on the one hand, and the inward movement of both eyes during fixation of near objects, on the other. Impairments of convergence can cause strabismus, among other conditions. What is the convergence response? Convergence is a specific type of opposite eye movement. Without … Convergence Reaction: Function, Tasks, Role & Diseases
Divergence is one of the vergence movements of the eyes and corresponds to a disjunctive movement that allows fixation of objects at a distance. The opposite eye movement is convergence, which is used to fixate objects in close proximity. It, too, is a vergence movement. Divergence disorders may refer to neurological damage. What are the … Vergence Movements: Function, Task & Diseases
Definition The visual acuity of the eyes is tested with an eye test. This indicates the resolving power of the eye, i.e. the ability of the retina to recognize two points as separate. The visual acuity defined as normal is at a visual acuity of 1.0 (100 percent). Adolescents often achieve even better visual acuity … Eye test
2. shihara color plates In 1917, this method with test images of different colored dots that form a complete picture was developed by the Japanese ophthalmologist Shinobu Ishihara. The test is based on the fact that “normal sighted people” can recognize different motifs by differentiating between red and green on the test images than people … 2. shihara color plates | Eye test

Progressive-vision contact lenses have a similar benefit for contact lens wearers as progressive-vision glasses do for eyeglass wearers: they enable sharp vision at near and far distances using the same medium. Today, these continuously technically advanced vision aids offer the same level of comfort as other contact lenses. What are varifocal contact lenses? Progressive contact … Gleaming Contact Lenses: Applications & Health Benefits
Definition School of vision The term “school of vision” is used to describe facilities at clinics or in ophthalmological practices where orthoptists work together with ophthalmologists to treat eye movement disorders such as strabismus and eye tremor, impaired vision and all diseases affecting the eyes. Today, the term “school of vision” is rather outdated, since … School of vision
Accommodation is the ability of the eye to dynamically adjust the refraction of light and, for this reason, to see objects clearly and sharply at any distance. What is accommodation? Accommodation is the ability of the eye to dynamically adjust the refraction of light and, for this reason, to see objects at any distance clearly … Accommodation: Function, Tasks, Role & Diseases
The symmetric tonic neck reflex is an early infant reflex that is physiologic until the third month of life. In the supine position, the examiner flexes the infant’s head, stimulating a reflex movement of the arms and legs. Persistence of the reflex beyond the first three months of life points to neurologic disorders. What is … Symmetrical Tonic Neck Reflex: Function, Tasks, Role & Diseases
