Generally, the result of different eye conditions will lead to the following types of impairment: a limited f
21、ield of vision, being unable to see to the sides or up and down; some loss of central vision limiting the ability to see fine detail; acute short-sightedness, seeing the world as a continuous blur; uncontrollable oscillations of the eyeball leading to an inability to see objects clearly; night blind
22、ness, a sensitivity to light and a tendency to be dazzled by glare. Visually impaired people detect information about the environment by the use of non-visual features, for example, audible and tactile features. A loss of sight is not accompanied by an increase in the effectiveness of other non-visu
23、al senses. However, visually impaired people generally place more emphasis on information received via other senses, for example the sense of touch. The use of tactile information When moving around the pedestrian environment, visually impaired people, using a range of mobility equipment including t
24、he long cane, will actively seek and make use of paving surface tactile information, particularly detectable contrasts in surface texture. The ability to detect contrasts in texture underfoot varies from one individual to another. For example, older visually impaired people and people who have lost
25、their sight through certain medical conditions, such as diabetes, may well have reduced sensitivity in their feet. It is important that tactile warning of potential hazards, e.g. a road crossing or a stair, are rigorous enough to be detectable by most people but without constituting a trip hazard or
26、 causing extreme discomfort. Considering the walking speed and the length of one step by a visually impaired pedestrian, the width of any warning surface is a critical parameter. The importance of luminance contrast In addition to tactile information those visually impaired people who have some resi
27、dual vision will also make use of the luminance contrast between surfaces for orientation and guidance. Those characteristics can therefore be used by designers, planners, engineers and others involved in the design of the built and pedestrian environments to accentuate the presence of hazards and a
28、menities. This Technical Specification cannot deal with luminance contrast since it relies on the difference between adjacent surfaces which need not both be tactile surfaces. However, manufacturers should be aware of this issue in considering the range of colour and tones they provide in their tact
29、ile products. CEN/TS 15209:20085 1 Scope This document specifies the nominal dimensions for surface profile features and patterns for the surfaces of pedestrian paving units, used to convey information for visually impaired people. It applies to paving units made of concrete, clay and stone. This do
30、cument does not specify requirements for visibility (colour, luminance contrast or profile) except where this visibility is provided by the tactile paving surface indicator. It does not specify material characteristics. NOTE 1 See Introduction for an explanation for the exclusion of luminance contra
31、st requirements.
