1. Always treat blind people as just another person as they simply do things differently.
2. Blind does not mean can’t nor does it mean stupid. It is only a physical challenge.
3. Bear in mind that blind people treat their guide dogs and white canes as extensions of their bodies. Never distract guide dogs from their job or touch, move or grab a cane without the owner’s permission.
4. Identify yourself and others who may be with you when meeting someone who is blind. Ideally, instead of saying "This is John" (or whoever), have those who are with you introduce themselves – one at a time – to the blind person. When conversing in a group, remember to identify the person to whom you are speaking, i.e. using their name — otherwise the blind person will be confused as to whether or not you are speaking to them. Remember: they can't see when you are and when you're not addressing them, so the use of names in conversation is essential for them to get their bearings and build a 'visual' image in their mind of everyone's positions and surrounding objects.
5. If you offer assistance, wait until the offer is accepted. Then listen or ask for instructions. Many blind people will accept help; however, make sure that they are aware that you are going to help them and offer your arm, not your whole body. See step #4 for what to do.
6. Do not clap, point, repeat or sing when attempting to guide a blind person. This would be somewhat rude, imagine how you would feel if someone was guiding you with clapping, pointing, or singing. Be consistent and specific when you are describing things and giving directions. The more accuracy, the more consistency, the more direct and the more description you use, the more effective your interaction will be. Blind people respond to intelligence.
7. Do not do for them what they can do for themselves such as serving themselves, finding things, getting things, carrying things etc. The last thing anyone needs is enablement for disablement.
8. Do not shout; just speak in a normal tone of voice as usual. Remember: they are blind, not deaf.
9. Relax. Don’t be embarrassed if you use common expressions such as “See you later” or “Did you hear about this?” that seems to relate to a person who is blind. Just as a person who uses a wheelchair still goes for a walk, a blind person will still be pleased — or not — to see you. In other words, blind people use the same expressions as those who are sighted.
10. Avoid stigmatizing words such as 'handicapped'. Blind people do not use that word in reference to themselves and few sighted people use it. Many blind individuals go as far to not use it. Don't use the word 'disabled' as it doesn't accurately describe them.
