Elderly Eyes Need High Index Lenses
Aging happens. It affects everything from muscular strength to organ function and from balance to eye health. Simple exercise can and will aid in the strengthening of the body, but extra precautions are necessary for optimal eye health in our senior years. For seniors who don’t know anything about high index lenses, a little education goes a long way. It will be necessary to understand how the eye ages, the diseases that affect the eyes in our senior years, in addition to how high index lenses can help.
How Eyes Age
As people enter their 40s, they notice blurry vision as well as inability to see clearly things that are close to them. The lenses begin to harden, which affects focus. This is a normal part of aging. Folks find themselves holding printed matter farther away from their faces, so they can read it. A change in eyeglass or contact prescriptions will be necessary.
Entering their 50s brings a little more trouble to the eyes of aging people. The near-sightedness or presbyopia gets worse. Cataracts begin to happen, and they have been happening at such an alarming rate that they are now considered a normal part of aging. When the lens of the eye becomes cloudy, cataracts are present. This affects the central vision. Progressive eyeglass prescriptions control the problem for a time, but cataract surgery often ensues.
Macular degeneration comes next. The macula is the middle part of the retina and is responsible for vision in the center of the eye. In our 60s, macular degeneration is characterized by blurry vision, the inability to discern straight lines, colors fade and black spots appear when we try to see something. Vision testing and eating foods rich in carotenoids (cucumbers, squashes, broccoli, mango and egg yolks) reduce the risk of this disease.
All of these increase the risk of blindness, but glaucoma is the worst. The optic nerve in the eye sends signals to the brain. Glaucoma destroys that nerve. Seeing an eye doctor each year is imperative in order to avoid this disease, as the primary symptom, eye pressure, doesn’t always show up. It is often mistaken for something else.
Wow, What Can be Done to Stop It?
It seems like a recording you can’t get away from, because every doctor in the world says it. Lifestyle changes including a good diet and exercise honestly do help most all diseases. Aging isn’t a disease, but its damaging effects can be and are mitigated by those two simple lifestyle changes.
Experts agree that diets high in Omega 3 fatty acids, vitamins, minerals and lutein help fight diseases that affect the eyes, diabetes, heart trouble and a host of other problems. The enemy here is free radicals, which rampage through the body sort of like Ms. Pacman causing damage. Brightly colored fresh fruits and vegetables are packed with anti-oxidants that take Ms. Pacman to the cleaners. Aging eyes benefit from the good effects of kale and spinach, dark leafy greens packed with good things for eyes. Also good for aging eyes is sweet corn, broccoli, peas and carrots. Vitamins A and C are essential to good vision, so plenty of bright colorful fruits should keep those diseases at bay.
What about Glasses?
Bifocals and trifocals are designed to bring focus to aging eyes at any distance. Progressive lenses don’t have the lines that bifocals and trifocals have, but do the same job. Obviously aging eyes don’t process light quite the same way, as discussed above. Luckily for aging eyes, high index lenses were invented. These lenses bend the light better than ordinary lenses. The higher the index, the better the light is bent. High index glasses come in bifocals, trifocals, progressive, tinted, anti-glare and whatever aging eyes need the most.
Aging eyes frequently need ever thicker lenses as time progresses. The beauty of high index lenses is that they are thin but do the same job. No more bug-eyed look from ever thickening lenses. No more broken noses from heavy glasses. Help those weakening aging eyes with high index lenses today.
