If Your Parents Had Cataracts Does That Mean You Will Too?

A close up of a person 's eye from the american academy of ophthalmologyIf your parents or grandparents had cataracts it’s normal to be concerned that you might develop them too. We often hear from patients who tell us about an older family member that could barely see out of a cloudy whitish-looking eye. They worry this will be their fate as well.

While genetics do increase your risk of developing cataracts, aging is more likely to be the culprit. According to the American Academy of Ophthalmology, cataracts affect more than 24.4 million Americans over the age of 40, and approximately half of all Americans have cataracts by age 75.

However, even if you develop cataracts—due to genetics, aging, a combination of both, or another medical condition—that doesn’t mean you’re destined for the same near-blinded cloudy-whitish eye scenario your older relative endured. With a basic understanding of cataracts, including the symptoms and what you can do to protect your eyes, you can maintain optimal vision as you age.

Symptoms Of Cataracts

A cataract is a clouding of the eye’s crystalline lens, which is just behind the pupil. This lens should be clear, so that it can effectively work with the cornea to focus light on the retina . If the lens becomes clouded, it’s considered a cataract, regardless of whether it’s causing reduced vision or not.

Cataract disease is progressive and it develops gradually, so you may not notice changes in your vision when cataracts first begin to develop. Over time, you may begin to experience symptoms of cataracts, such as:

  • Blurry vision.
  • Dimmed vision
  • Seeing double, but only in one eye.
  • Extra sensitivity to light.
  • Difficulty seeing well at night, or needing more light when you read.
  • Bright colors appear faded or yellowish, like an old newspaper.
  • Seeing halos around lights.

How To Reduce The Risk Of Developing Cataracts

Other than genetics and aging, there are a few conditions that raise your chances of having cataracts. Certain medical conditions, such as diabetes, increase the risk of developing cataracts, so maintaining your overall health as you age will affect your eye health as well.

Previous eye surgeries or injuries can also increase the risk of developing cataracts, so protect your eyes wisely. Likewise, spending too much time in the sun without sunglasses can damage your eye proteins and start the process of cataract formation. Protect your eyes with a wide brimmed hat or sunglasses that are rated for UV (ultraviolet light) protection.

The best way to stay on top of cataracts, however, is to schedule annual comprehensive eye examinations. An ophthalmologist can detect cataracts by examining the front part of the eye, including the lens, with a biomicroscope, and the back part of the eye with an ophthalmoscope.

(Keep in mind that a comprehensive eye exam is not the same thing as a vision screening. A vision screening is basically a visual acuity test that can be performed anywhere glasses are sold, and it does not detect cataracts. Schedule a comprehensive eye exam once a year, especially if you are diabetic and/or over the age of 40, for a thorough evaluation of your eyes.)

Depending on your cataract diagnosis, your ophthalmologist can tell you whether your cataracts are likely to progress slowly or rapidly, and can tell you if you’re a candidate for cataract surgery Today’s advanced, outpatient cataract surgery procedures lead to improved vision in more than 95% of cases in which cataracts are the only issue.

Diabetes affects various parts of the body, including your eyes. Keeping your blood sugar under control is not just good for your health overall, but it also helps protect your eyesight. Over time, high blood sugar can irritate the tiny blood vessels in your eyes and increase your risk of serious eye problems. Knowing how diabetes and eye health are linked can help you identify issues and take measures to protect your sight. How Does Diabetes Affect Eye Health? When blood sugar stays high, it can damage the blood vessels in the retina, which is the part of your eye that senses light and helps you see. Damaged blood vessels might leak fluid, swell, or change how well the retina works. Diabetic eye problems usually develop slowly, so you might not pick up on any changes in your vision until significant damage has occurred. That’s why it’s important for people with diabetes to get regular eye exams, even if their eyesight seems fine. Common Eye Conditions Linked to Diabetes People with diabetes are more likely to have certain eye problems. Finding and treating these issues early can lower the chance of losing vision permanently. 1. Diabetic Retinopathy Diabetic retinopathy is a common eye issue that happens when high blood sugar damages the retinal blood vessels. These damaged vessels may leak fluid, which may cause blurry vision, dark spots, or changes in how you see. In advanced cases, abnormal blood vessel growth can lead to serious problems. If diabetic retinopathy worsens, new abnormal blood vessels can grow, causing serious problems, including vision loss. Getting regular eye exams can help catch these changes early, before they become severe. When fluid is retained in the macula (part of the retina which focuses on sharp central vision), this swelling can make it harder to read, recognize faces, or see fine details clearly. When detected early, treatments can help reduce swelling and protect your eyesight. 3. Cataracts People with diabetes have a higher chance of getting cataracts early. Cataracts occur when the lens in your eye becomes cloudy, which can cause blurry vision, increased sensitivity to glare, and difficulty seeing clearly. While cataracts come with age, having diabetes can make them appear sooner or progress quicker. 4. Glaucoma Diabetes can also raise your risk for glaucoma, which is a group of eye diseases that harm the optic nerve. Glaucoma usually starts without any clear symptoms, but if it is not treated, it can cause permanent vision loss. Routine regular eye exams are important for finding glaucoma early and keeping your eyes healthy Diabetes-related eye problems might not cause symptoms at first. Still, there are some warning signs you should look out for: • Blurry or distorted vision • Difficulty focusing • Dark spots, floaters, or shadows in your sight • Increased sensitivity to glare • Trouble seeing colors clearly • Sudden alterations in vision • Partial or complete loss of vision If you notice sudden vision changes, contact an eye doctor as soon as possible. The Value of Regular Eye Exams for People With Diabetes Getting a full eye exam is one of the best ways to protect your vision if you have diabetes. During the examination, your physician will study your retina, look for symptoms of diabetic eye disease, and track any changes over time. Many eye problems linked to diabetes can be treated more easily if they are found early. Regular checkups help your eye doctor give you advice that fits your own eye health and diabetes care. Protecting Your Eyes When You Have Diabetes Looking after your general health is important for keeping your eyes healthy. Here are some things you can do to protect your vision: • Keeping blood sugar levels under control • Managing blood pressure and cholesterol • Scheduling regular diabetic eye exams • Following your diabetes treatment plan • Eating a balanced diet that promotes eye health • Avoiding smoking, which increases the risk of eye complications Prioritizing Your Vision and Eye Health Diabetes and eye health are closely linked, but you can lower your risk of serious vision problems by taking action early. Getting regular eye exams, making healthy choices, and managing your diabetes all help protect your eyesight. If you have diabetes, seeing your eye doctor regularly can help catch changes early and keep your vision clear for the future. Your eyes are a key part of your health, so make caring for them a priority at every age.

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.
