My wife is blind and we have moved quite a bit both in the U.S. and around the world. So here is my advice:
1. Face the issue straight up. You are likely the first blind person anyone in the ward ever meet. They are going to judge, right or wrong, all blind people based on their interaction with you. Tell people how you would like to be treated. The ACB has a little pamphlet on the subject and we got them and handed them out to member of the ward.
2. Meet with your new bishop and explain to him the issues and give him one of these pamphlets as well.
3. In one ward my wife gave a talk in sacrament about blindness and how to treat blind people correctly
4. Try to avoid becoming the ward's service project. Make sure you take part in giving service and not get on the receiving end.
5. If you use a guide dog you will find, if you haven't already, that the biggest problem with people in church will be with the adult men. Children learn in school not to touch or bother the dog, it is my observation that women will seldom fuss over the dog. But adult men need to be reminded not to. It got so bad in one ward we were in that the Bishop had to get up in priesthood meeting and tell the brethren to leave the dog alone.
This is from the ACB website may be useful as well.
WHEN YOU MEET A BLIND PERSON....
Many people are uneasy when thinking about assisting a visually impaired person. The following suggestions will help you feel at ease with blind persons, and are based on thoughtful courtesies you might extend to anyone, sighted or blind.
• There are many ways in which you can be helpful to a blind person in everyday situations, but always ask if the person wishes assistance. If help is needed, they'll be grateful. If not, they will thank you for asking.
• Speaking upon entering a room where there is a blind person is very helpful. Identify yourself and let them know when you're leaving. Don't exit without informing them and leave them talking to thin air.
• When greeting a blind person if others are present, use a name or provide some cue so the blind person can tell for whom your greeting is intended. Remember that blind people can't see when you're looking at them.
• Address a blind person directly, not through someone else, and use a normal tone of voice. When giving directions to a blind person, be specific. Pointing will not help, nor will "over there." Phrases such as "do you see what I mean" or "let's look at the numbers" are a normal part of everyday conversation, so you needn't censor your conversation. Remember, too, that nods and shrugs do not take the place of words.
• If the blind person chooses to accept assistance with moving through an environment, it will be easiest for him or her to hold onto your arm just above the elbow when walking. This will position you about ½ step ahead, and the individual can easily follow your movements. Pause briefly before ascending or descending steps and inform the individual as to whether they are going up or down. When providing assistance to cross the street, stay with the person until the opposite curb has been safely reached.
• Avoid the temptation to pet a dog guide. The dog is a working animal responsible for leading a person who cannot see and should not be distracted or treated like a pet.
• When escorting a blind person to a chair, place his or her hand on the back of the chair or if approaching from the front, guide the individual to a position where he or she can contact the chair with his or her leg. If you take them to a car or bus, guide their hands to the door handle. They'll manage the rest.
• When you dine with a blind person it can be helpful to describe the table setting. The location of food servings can be described as numerals on a clock face, I.E. "your mashed potatoes are at 7 o'clock."
• If you have a money transaction, identify the denomination of the bills so that he or she may fold them according to the individual's own method for identification.
• The most important things needed when you meet blind individuals are your good will and common sense. Remember that blind people think, feel and make decisions just as you do. A blind person is an individual who has usually lost only one sense-the sense of sight. Be natural and enjoy one another.
