Abstract

Vision is compatibility to see with clear perception on details, colors, contrast and to make visually
difference for subject. Eye vision has tendency to get worse or naturally decrease or change with age. Determination
of refraction for the patients with weak vision contains many medical examinations by an ophthalmologist or an
optometrist. Refraction can be examined with subjective and objective methods or techniques. The subjective
method is performed with board which is called optotype. The optotype has symbols, numbers and letters in various
sizes. Subjective technique usually is not sufficient to get realistic insight of the refractive error, especially not it’s
magnitude. There are multiple methods for objective determination refraction such as refractometry, retinoscopy,
ophthalmoscopy, photoscopy. On many occasions reduction in visual ability can be corrected with glasses, contact
lenses, medications or surgery. However, if visual changes occurred because of incurable illness on the eyes,
condition or injury, the loss of vision can be permanent. Many people around the world with permanently demaged
eye vision have a determined residual vision which can be used with the assistance of materials and devices for poor
eye vision. The work describes different aids that are used for improving residual vision, including optical and nonoptical devices, such as electronic devices. The aids for poor eye vision play an important role in the rehabilitation
of it. The optical aids for poor eye vision maximize the use of the remining vision with the assistance of a telescope
or a magnifying glass at around 70% of the patients, appropriately. The aids for poor eye vision are available for
various tasks and distances and range from simple magnifying glasses, and telescopes to video amplifiers with high
magnification power. The way of approach towards the patients indicates what will be the overall outcome of the
poor eye vision test. Faith ant will are a positive addition to the patient’s successful treatment and it is most
important for dealing with the disease and in utilization of the visual potential of the treated patient’s eye. The most
common conditions that are a cause for poor eye vision in patients are refractive errors (myopia, hypermetropia,
astigmatism). The healing mostly depends on the measures taken, how and when, at what age and what treatment.
Also, the emotional and psychological aspects, such as stress and depression, are significant challenges which these
people are facing and therefore the support and the understanding of the community play an important role in
improving the quality of life of the people with damaged eye vision.
