The National Eye Institute (NEI) predicts that by the year 2050, 50.2 million Americans will develop cataracts. But don’t worry. Cataracts are a normal part of the aging process, currently affecting more than 22 million Americans age 40 and older, and half of all Americans over the age of 80, according to NEI. In a healthy eye, the lens focuses “light onto the retina for clear vision” and “adjusts the eye’s focus, letting us see things clearly both up close and far away,” explains Gretchyn Bailey, editor in chief of Optometry Times. Over time, proteins begin to build up in the lens, forming protein clumps, which can obscure normal vision. These clumps, or deposits, prevent light from passing clearly through the lens, causing images to appear cloudy or blurry, especially at night.
Currently, 2.7 million people in the United States over the age of 40 have glaucoma, one of the leading causes of irreversible vision loss in the U.S. Still, understanding and awareness of glaucoma is relatively low, according to a 2013 American Optometric Association (AOA) survey of 1,000 Americans. Key findings include: [Read more…]
As we age, our eyes age right along with us. It’s a natural part of getting older, but that doesn’t make it any less scary. In fact, vision loss was rated as the No. 1 health concern among aging adults, according to a recent study out of the Wilmer Eye Institute at Johns Hopkins University School of Medicine. We all fear losing our independence, but there comes a time in all of our lives when we find ourselves relying on another person, often an adult child, to help with day-to-day activities. It’s nothing to be ashamed of. It’s a normal part of aging, especially when decreased vision is present. The important thing is learning how to work together, while also respecting one another’s independence.
Fostering a Good Relationship between Adult Children and Aging Parents
Currently, over 65.7 million Americans provide care for a family member or loved one, according to the National Alliance for Caregiving, and 36% of those are caring for an elderly parent. And it’s not always easy, especially if the situation is still very new. There can be pushback from both sides as parent and child learn to accept their new roles and work together. But as you both settle into this new dynamic, it is important to look at the bigger picture, especially in terms of vision health.
Low vision ranks just behind arthritis and heart disease as the third most common chronic cause of impaired functioning in people over 70, says Dr. Eric A. Rosenberg of Weill Cornell Medical College and Laura C. Sperazza, a New York optometrist. Most aging adults who experience low vision are often affected by one of four conditions:
Macular Degeneration: The leading cause of irreversible blindness in people over the age of 65, Age-Related Macular Degeneration (AMD), is a progressive eye disease that causes damage to the Macula, which is the most concentrated central portion of the retina. AMD causes the light-sensitive cells in the Macula to break down and die, affecting central vision, causing blind or blurry spots that grow as AMD progresses. This can begin to make simple, everyday tasks – like reading and driving – difficult or even impossible. Additional symptoms and warning signs include straight lines look wavy and a need for more light.
Glaucoma: Glaucoma is the result of increased intraocular eye pressure (IOP) and damage the optic nerve, the nerve that carries visual information from the eye to the brain. Glaucoma is the second leading cause of blindness globally, after cataracts, and affects roughly 60 million people worldwide, including over 3 million Americans. What’s scarier is that roughly half of those people – nearly 30 million people – don’t even know they have glaucoma, because there are no initial warning signs, no symptoms. Common symptoms and warning signs include gradual loss of peripheral, or side, vision; difficulty driving at night; and loss of contrast.
Cataracts: It’s estimated more than 24 million Americans, age 40 and older, have cataracts, a cloudy or opaque area in the normally clear lens of the eye, which is located behind the iris, the colored part of the eye. Normally, the lens focuses light on the retina; however, as we grow older proteins begin to build up in the lens, forming protein clumps, which prevents light from passing clearly through the lens. This causes images to appear cloudy or blurry, especially at night. Common symptoms and warning signs include hazy vision, difficulty driving at night, double vision, trouble distinguishing colors, and sensitivity to glare.
Diabetic Retinopathy: If you have diabetes, you are not alone. More than 25.8 million Americans, 8.3% of the population, have diabetes. These people are also at risk of developing Diabetic Retinopathy, the most common diabetic eye disease. This is why it is important to not only seek regular medical care, but also annual eye exams. Believe it or not, diabetes is the leading cause of new cases of blindness. Common symptoms and warning signs include blurred or changing vision, difficulty reading, floaters, and loss of central or peripheral vision.
“You should be able to truly live connected to the world around you and sight is a huge part of that,” says April Pevear, Patient Care Specialist at Anne Arundel Eye Center.
How to Identify Potential Vision Issues
While minor, gradual changes in vision can be a natural part of the aging process, sudden or severe changes are often a warning sign of a more pressing issue. There are several warning signs to potential vision issues that you should look for. These include gradual or sudden vision loss, blurred or hazy vision, double vision, eye pain, seeing flashes of light, eye often twitches, halos around lights, discharge from the eye, waviness of vision, changes in the color of the iris or clarity of the cornea, trouble distinguishing faces, and difficulty performing everyday activities, such as reading. If you notice these or anything else that seems out of the norm, it is important to contact your ophthalmologist, especially if these warning signs are severe and persistent.
How Often Should an Aging Adult See an Eye Doctor?
Even if no obvious warning signs are present, the American Academy of Ophthalmology recommends adults over the age of 65 have a complete eye exam every one to two years. Depending on vision health, an ophthalmologist may recommend more frequent visits, especially if one of the aforementioned conditions is present. A person may also need more frequent eye exams if they have certain medical conditions, like diabetes or high blood pressure, which may put him at higher risk for some eye diseases.
Partnering with Anne Arundel Eye Center
At the Anne Arundel Eye Center, we do our best to partner with aging adults and their families and caregivers to provide the highest quality eyecare.
“One of the things that sets our practice apart from others is that we realize that our patients are family oriented and we are too,” says Pevear. “We work to not just treat the illness or condition but also to educate the patient and the adult child who is their caregiver now.”
Staffed by caring and knowledgeable professionals, the Anne Arundel Eye Center is a regional leader in the diagnosis and treatment of glaucoma and cataracts. Our state-of-the-art treatment center is dedicated to making the best eye care accessible to everyone.
If you have any questions, please contact Dr. Samuel Boles, Dr. Nicole Kershner Regis, Dr. Kathryn Turner, and the eye care specialists here at AAEC by calling 410-224-2010. AAEC is staffed by caring and knowledgeable professionals who will help guide you on your healing journey.
In a new study published on March 7, 2017 by PLoS One, a team of researchers from the Graduate Institute of Clinical Medical Science in Taiwain, led by principal investigator Ji-An Liang, MD, found that the hepatitis C virus (HCV) increases cataract risk, particularly if treated with interferon-ribavirin.

According to a recent study out of the Wilmer Eye Institute at Johns Hopkins University School of Medicine, nearly 50 percent of people (47.4 percent) of the 2,044 U.S. adults polled rated vision loss as the worst possible health outcome, surpassing such other conditions as loss of limb, memory, hearing, or speech. Top concerns among respondents were a diminishing quality of life ranked followed closely by loss of independence. [Read more…]
