Survey Shows That What You Don’t Know About Vision Loss May A Big Problem

Baptist Eye Surgeons • March 13, 2020

Vision LossMany studies have shown that people fear blindness as much if not more than they fear cancer, heart disease, stroke, and other serious health problems. However, one new study shows that the vision loss that Americans are scared about is actually an issue they know very little about. The year 2020, with all its symbolism with clear vision, is the year to change that.

The number of people who will be affected by eye diseases that cause vision loss or blindness is expected to double in the years ahead, which makes it critical that people understand what puts them at risk for vision loss.

Unfortunately, a recent survey conducted by The Harris Poll about what Americans actually know when it comes to caring for their vision shows that we have a long way to go in helping people better understand eye health.

For the survey, more than 3,500 U.S. adults age 18 and older were asked general questions by The Harris Poll on behalf of the American Academy of Ophthalmology in August 2019.

Here are some of the key findings:

  • While 81% of adults say they consider themselves to be knowledgeable about eye and vision health, only 19% were able to correctly identify the 3 main causes of blindness in the U.S.— glaucoma, macular degeneration, and diabetic eye disease.
  • Only 37% of adults know that you may not have any symptoms of these leading causes of blindness until permanent vision loss occurs.
  • Less than half, 47% , are aware that your brain can make subtle adjustments in an attempt to adapt to vision loss, which makes it hard to tell if you are losing your vision until permanent damage is too difficult to ignore, much less reverse.
  • While over half, 57% , are aware that vision loss in adults increases the risk for injury or death , only 24% know that vision loss in adults is also associated with psychological problems such as social isolation and depression.
  • Less than half, 47%, understand that vision loss and blindness does not affect all people equally and that some populations of Americans are affected by certain eye diseases more than others.

This survey goes to show that what many Americans don’t know about the health of our eyes and the potential for permanent vision loss—including blindness—can have major, life-altering consequences.

Unfortunately, too many of us choose to be reactive when it comes to the health of our eyes by waiting for symptoms to appear or for our vision to become too compromised before seeking help. However, in many cases, much of our vision could have been preserved had we been proactive by having regular eye exams with an ophthalmologist who would be able to detect eye diseases early.

Educating yourself about eye diseases and visiting an ophthalmologist regularly is the best thing you can do for the health of your eyes and your vision. Ophthalmologists are medical and surgical physicians who are extensively trained to recognize all the potential threats to vision, which is why the Academy recommends that healthy adults see an ophthalmologist for a comprehensive, baseline eye exam by age 40 and have their eyes checked every year or two thereafter.

If you are older and/or have a higher risk of certain eye diseases, based on your family history or medical conditions, you’ll want to consult with your ophthalmologist about how often you should have comprehensive eye exams. Doing so can save your vision.

Night vision problems can make everyday activities like driving at dusk, walking in poorly lit places, or adjusting to indoor lighting harder and sometimes unsafe. Trouble seeing in low light, called nyctalopia, is not a disease itself but a sign that something else may be affecting your eyes. Learning what causes night vision problems and when to get help is important for keeping your vision healthy. What Are Night Vision Problems? Night vision problems mean it is hard to see clearly in low light or darkness. Some people notice their eyes take longer to adjust when going from bright to dim places. Others may have trouble with glare from headlights, seeing less contrast, or things just looking dimmer at night. Mild changes in night vision can happen as you get older, but if your symptoms keep getting worse or do not go away, you should pay attention to them. Common Causes of Night Vision Difficulties There are several potential causes of night vision problems. Night vision problems can have many causes, from getting older to certain eye conditions, such as lens problems, leading to blurred vision and increased sensitivity to glare. They are one of the most common causes of poor night vision, especially in older adults. 1. Cataracts Cataracts cause clouding of the eye’s natural lens, leading to blurred vision and increased sensitivity to glare. They are one of the most common causes of poor night vision, especially in older adults. 2. Vitamin A Deficiency Vitamin A is important for keeping your retina healthy. If you do not get enough vitamin A, your eyes may have trouble adjusting to darkness, which can lead to night blindness. 3. Glaucoma Some types of glaucoma can affect your side vision and make it harder to see differences between light and dark. As the optic nerve gets damaged, seeing in low light can become more difficult. 4. Retinitis Pigmentosa This inherited eye condition slowly affects your ability to see at night and to the sides. Early signs often include trouble seeing in the dark. 5. Diabetes-Related Eye Disease Diabetic retinopathy can harm the blood vessels in your retina, which may cause blurry vision and make it harder to see at night. 6. Aging and Pupil Changes As people get older, their pupils do not react to light changes as quickly, and the retina becomes less sensitive. This naturally makes night vision worse over time. Symptoms to Watch For Night vision problems often develop slowly. Some common signs are: Difficulty seeing in low light or darkness Trouble driving at night due to glare from headlights Longer adjustment time when moving between light and dark environments Reduced contrast or clarity in dim settings Frequent squinting or eye strain in low light If these symptoms start to affect your daily life, it is a good idea to get a full eye check-up. When to See an Eye Doctor You should see an eye doctor if you notice new night vision problems, if they are getting worse, or if you have other changes in your vision. The doctor can run tests to find out what is causing the problem and suggest the right treatment. A full eye exam might include checking your retina, testing your field of vision, and taking images to look at your eye health. Finding problems early is very important for conditions like glaucoma, diabetic eye disease, and retinal disorders, because early treatment can help protect your vision. Protecting Your Night Vision Not all causes of night vision loss can be prevented, but taking care of your eyes can lower your risk and help you see better. Some helpful steps are: Scheduling regular eye exams Handling chronic health conditions like diabetes Eating a diet rich in vitamin A and antioxidants Wearing proper corrective lenses if prescribed Avoiding driving with untreated vision changes Prioritizing Your Eye Health Night vision problems can be an early sign of eye disease. Since many eye problems develop slowly, having regular eye exams is one of the best ways to catch changes early and keep your vision healthy for the long term. If you have trouble seeing at night or notice any changes in your vision, making an appointment for an eye exam can help keep your eyes healthy and your vision clear in all types of light.
