(ARA) — Thick-lensed glasses with bifocal lines, dentures that look too perfect to be real and, of course, bulky, heavy hearing aids that just can’t be overlooked - once, there was no mistaking the signs of age. Many people chose to endure the inconveniences of aging, rather than wear the overly obvious devices that might have eased vision and hearing losses.Products like bifocal contact lenses and virtually invisible hearing aids can make some of the natural bodily changes associated with growing older seem less obvious and reduce their impact on a person’s quality of life. “Your eye doctor may start talking about bifocals when you enter your 40s, and by the time you are in your 50s, you may notice a difference in your hearing,” says Dr. Barry Freeman from hearing aid maker Starkey Laboratories, Inc.
