Technology has opened up new avenues for those patients requiring glasses.  Not only is the vision clearer and more comfortable in the newer materials, but the lenses are also thinner and lighter and, in many cases, more shatter-resistant.    The newer-generation antireflective coatings are also more scratch-resistant than their predecessors and provide improved night vision.  One of our opticians would be glad to help you decide which lens material is best for you.
