What to Eat When You’re Eating Out: What to Eat in America’s Most Popular Chain Restaurants

Grey hair, wrinkles, loss of hearing and not being able to read a book without the assistance of eyeglasses or mulitfocal contact lenses are all signs that the human growth hormone switch has been turned off and we are getting older. One of the biggest challenges that we face as we age is diminished eyesight. Presbyopia or the inability to focus on objects close to us is a condition that can occur anytime after 40 or 50. Actually the inability to focus on objects close to us is a gradual process. As we age the ciliary muscles that straighten and bend the eye lens lose power. Our eye lens changes its curvature due to muscle issues. There is a loss of crystalline lens elasticity, which creates the condition known as Presbyopia.
The focusing mechanism is an interesting one. The lens of the eye is suspended using tension from a membrane known as the zonula. When the ciliary muscle contracts tension is released and the lens flattens to see and read at the near point or the closest point that the eye can focus on. Some medical professionals believe that the ciliary muscles are ligaments, which are not under the control of the nervous system. Regardless of whether they are muscles or ligaments, the fact remains that the aging process does weaken them and that could be the result of a HGH deficiency.
The cure for Presbyopia through the years has been reading glasses with lenses that magnifies the print or the object of interest. Multifocal contact lenses are now available that have the ability to bring distant and near vision into focus without the need for reading glasses. There are other types of multifocal contact lenses that gradually change in lens power. Progressive eyeglass lenses are available in soft or the rigid version, which is also known as gas permeable lens material. They can be worn daily and certain designs can be worn overnight. Multifocal soft contact lenses are also made as a disposable product that can be discarded at the end of the day, which means there’s no need to clean them or care for them in any way.
