Adjustable blinds or curtains may be helpful in controlling light levels. To minimise glare, overhead lighting should be recessed wherever possible and light sources should be placed so as to not shine directly into the eyes. Overall lighting should avoid patches or sudden changes from brightly lit to dark areas. The rapid adjustments necessary to accommodate the changes in light levels can be both difficult and uncomfortable for patrons with a vision impairment. Entrances and lobby areas may require a slight adjustment in light levels to aid the transition from natural light to an artificially lit environment indoors.
Signage Be consistent with both style and placement of signage.
People with low vision can also receive information from visual displays. The location of signs is as important as the lettering. Interior signs should be placed at eye level near doorways or traffic areas, and clearly defined. Use large print signs with good, bold text and clear contrast such as black on white. Signs placed on glass panels or doors can be difficult to read and should generally be avoided.
