if you are a technology explorer maybe you can help a short-sighted friend to turn on the accessibility function on their smart-phone. Just don’t leave them with the changes until you are sure that it really is suitable for their needs. Remember too that the cell phone cameras can be used as a magnifying glass to read things like the electricity meter or temperature on the oven dials. I even use it to see weight measurements on the kitchen and bathroom scales. My phone is like a hand-held eye… is that why they call it an iPhone?
