VISUAL IMPAIRMENT 1



In-class tasks


1. Try to sum up the basic facts about “low vision“ from the text you were supposed to read as
homework (Odpovědník: Visual Impairment 1). Use your own words.




2. Put the following levels of visual impairment into the correct order:


normal vision                                   blindness                  moderate visual
impairment

severe visual impairment                mild visual impairment



1……………………………………..                                                     ………………………………

2…………………………………….                                                      ………………………………

3…………………………………….       the person is called             ………………………………

4…………………………………….                                                      ………………………………



Now write next to each of the stages of visual impairment how we can call the individuals with this
particular level of  visual impairment.



3. What is the difference between the terms:



BLIND  X  PARTIALLY SIGHTED                  ?






4. Fill in the missing words choosing from the offered ones:

assistance       neurological                acuity               total blindness
approximately

severe              blindness        sighted                        no light perception
classified

…………………… is the condition of lacking visual perception due to physiological or …………………… factors.

Various scales have been developed to describe the extent of vision loss and define blindness
……………………….. is the complete lack of form and visual light perception and is clinically recorded as
NLP, an abbreviation for "………………………..." Blindness is frequently used to describe …………………. visual
impairment with residual vision. Those described as having only light perception have no more sight
than the ability to tell light from dark and the general direction of a light source.

In order to determine which people may need special ………………….. because of their visual disabilities,
there have been formulated more complex definitions referred to as legal blindness.In North America
and most of Europe, legal blindness is defined as visual ……………………….. (vision) of 20/200 (6/60) or
less in the better eye with best correction possible. This means that a legally blind individual
would have to stand 20 feet (6.1 m) from an object to see it—with corrective lenses—with the same
degree of clarity as a normally ………………………. person could from 200 feet (61 m). In many areas, people
with average acuity who nonetheless have a visual field of less than 20 degrees (the norm being 180
degrees) are also .................... as being legally blind…

……………………. ten percent of those considered legally blind, by any measure, have no vision. The rest
have some vision, from light perception alone to relatively good acuity. Low vision is sometimes
used to describe visual acuities from 20/70 to 20/200.
