Everyone wants to know how the things we eat can affect the way our bodies function. Maybe it’s because we want even more reasons to eat healthy, or because more of us want natural ways to lower our risk for diseases and deficiencies, but the good news is that you can easily eat right for your vision. There are many delicious foods that can help promote overall health and may be part of a plan to lower your risk for eye disease.

Antioxidants
Many foods contain antioxidants, which are substances that remove oxidizing agents in living organisms. These oxidizing agents may be potentially damaging to our various systems, so many people believe that foods rich in antioxidants could help lower our risk for certain illnesses.

Vitamin C (ascorbic acid) helps with building and maintaining connective tissues in the human body. It also helps maintain collagen found in the cornea. By promoting healthy skin, bones, and circulation, you retina may be aided by vitamin C. People who have healthy levels of vitamin C in their diet are also at a lower risk of forming a cataract and vision loss from macular degeneration.

Red peppers are especially high in vitamin C, as are green peppers, strawberries, broccoli, and some citrus fruits.

Flavonoids
Many of the foods that contain vitamin C also contain flavonoids. Unlike vitamins, these substances are not necessarily required for life and crucial functions of the body, but they are generally linked with health benefits as part of an overall healthy diet.

Anthocyanins are a type of pigment and antioxidant that are considered good for your eyes because they may reduce risk of cataracts or macular degeneration. These substances are found in many berries like blueberries, cranberries, raspberries, and blackberries. You can also get anthocyanins from grapes, red cabbage, and red apples.

Fatty Acids
Many people falsely believe all fat is bad, but there are lots of healthy fats that we need in our diets. Our brains demand various kinds of fats to function properly, and healthy fats help our circulation, digestion, and even things like our outward appearance. Diets with proper omega-3 fatty acids are also very good for your eyes, and are especially helpful in patients with dry eyes or macular degeneration.

You can get these essential nutrients from foods like flaxseed, walnuts, fish, soy, and veggies like Brussels sprouts and cauliflower.

Though we can’t quantify for certain how much these foods help lower our risk for illnesses, there’s no doubt that a balanced diet and healthful lifestyle are important for a strong body and healthy eyes!

Most of us remember being told not to sit too close to the TV because it would ruin our vision. Well, that may have been an exaggeration of the actual dangers of sitting too near a tube television, but new risks are at play when it comes to electronic screens and the eyes of our children.

Historically, old tube televisions and things like handheld games relied on much different electronics and lights to power their screens. It wasn’t until much more recently that we have moved to bright LED and plasma screens that use a lot of blue light to show unimaginably crisp images. Whereas sitting pretty close to and older style screen twenty years ago probably wasn’t a good idea, it’s likely that prolonged and extreme use of screens nowadays is more problematic.

We know that using a computer can improve school readiness and academic achievement. Children learn digital tools quickly, and have relatively little trouble using them for educational games, math, reading, and more. These devices aid cognitive development when used appropriately, and will not harm your child’s vision. The risks associated with using a digital screen come from prolonged use, improper ergonomics, and developmental problems caused by getting too much screen time instead of getting social interaction and physical activity.

When children use a digital device for long periods of time, they do not “flex” their eyes by focusing on distant objects, as well as looking in the near and intermediate fields. This causes eyestrain. Additionally, sitting for too long and making repetitive movements with hands (like clicking a mouse or controller) or sitting in a position with bad posture or an unsupported upper body can lead to problems like carpal tunnel syndrome and muscle soreness. Everyone knows that kids need time to burn off energy, build gross motor skills, and strengthen their muscles and bones through exercise and play. When they get too much time sitting down while indoors, other important activities like outdoor play, conversation, spacial reasoning, and other skills suffer.

To reduce your child’s risk of computer vision syndrome:

• Limit their time on computers and devices
• Encourage them to take breaks regularly (this is a good habit for many activities)
• Make sure they are sitting in a comfortable, supported position
• Opt for anti-glare protection on their eyewear to reduce eyestrain
• Teach them to view digital screens at arm’s length and not too close

When it comes to pediatric care, parents are usually concerned with finding the best pediatrician and following their medical advice exactly, but what about pediatric eye care? Eye care for kids is sometimes an area parents overlook because they aren’t always aware of the importance of eye health for children. Many don’t seek eye exams for their children until either the child reports having difficulty seeing at school, or the child’s grades begin to slip and parents take a closer look at why their child isn’t developing academically.

Experts recommend that children receive several eye exams before starting school. Infants should receive their first comprehensive eye exam around six months of age. Believe it or not, there are tests that can be done to determine the overall health and visual function of an infant’s eyes at such a young age. Visit www.infantsee.org for more details on infant vision and eye health. Children should then have an eye exam around age three, and again when they reach age five or six. Before reaching first grade, parents are strongly encouraged to have their children receive a full eye exam to make sure the child has no visual problems as they start elementary school.

Eye exams for young children are important because vision problems can negatively affect a child’s performance in school long before you are aware of the issue. The American Optometric Association reports that 5 to 10 percent of preschoolers and 25 percent of school-age children are diagnosed with vision problems once they receive proper eye care. Experts are always stressing the significance of appropriate early education and full participation from youngsters in programs and learning that will become a foundation for critical skills. Children risk not being able to fully participate if they are experiencing undiagnosed visual impairments. An early eye exam and regular eye care for children can alleviate this potential problem.

Identifying eye problems early is crucial to the child’s learning and development in school. A child with poor vision may have difficulty with seeing text and comprehending words causing difficulty in reading. No parent wants their child to be frustrated with reading, especially when most vision problems are easily fixed with glasses. Unable to explain problems in a group, children may choose not to volunteer for reading in class out of embarrassment, or opt out of picking a library book because it’s hard to see. This will negatively affect academic achievement and the enjoyment that comes with reading for many children.

Other symptoms of learning-related vision problems include headaches or eyestrain, short attention span for visual tasks, difficulty identifying or reproducing shapes, poor hand-eye coordination, and developmental delay. Talk to your optometrist about scheduling eye care visits for your children. They will be more than happy to answer any questions you may have about your child’s eye health, and let you know when is a good time to start doing regular check-ups.

Taking care of your eyes includes more than going to a yearly exam and wearing an up-to-date prescription. Although both are certainly important, there are many more things you can (and should) do to make sure you’re preventing eye problems and protecting your vision.

Diet and nutrition play an important role in the long-term health of your eyes. Certain vitamins and minerals have proven necessary for good vision while also protecting against eye diseases. A diet high in dark leafy greens such as spinach, kale, and collard greens provides us with lutein, bioflavonoids, and beta-carotene. Omega-3 fatty acids are great for those who suffer from dry eyes. Omega-3s can be found in fish, fish oil supplements, flaxseed, and walnuts. Vitamin A, C, D, E and zinc can be consumed through foods such as eggs, sweet peppers, milk, almonds, and beef. Consumption of these foods high in vitamins may reduce the risk of macular degeneration, cataracts, blindness, and dry eyes, among others.

Full-body physical exams are also important. Physicals check for diabetes and high blood pressure. These conditions can lead to diabetic retinopathy, macular degeneration, glaucoma, and ocular hypertension if left untreated.

Shielding your eyes from the sun is important, but many people believe it is just the tint of sunglasses that offers protection. In actuality it’s the ultraviolet-blocking abilities of sunglasses that guard your eyes from damage. Make sure that your eyewear is dark enough to keep you from squinting into the sun when you’re outdoors, but also check that your glasses have suitable UV protection. Some sunglasses have an inexpensive UV coating that rubs off over time, so your best bet is to purchase a reputable brand that offers a durable coating or is manufactured into the lens itself and will block 99–100% of UVA and UVB rays.

The number of people in the United States who smoke has been declining for several years, and now just 18% of people in the US smoke. Unfortunately, smoking still accounts for 480,000 deaths each year, and smoking increases several risk factors for poor eye health. Smoking doubles your chance of developing cataracts, a clouding of the eye that is a leading cause of blindness. Also, age-related macular degeneration (AMD) causes blind spots in your central vision, and smokers have a three-fold increase in their risk of developing AMD. So quitting smoking is crucial for your overall health, but also to protect your eyesight.

Most people know that they should be getting twenty minutes of exercise three times a week, but eye health is yet another reason that you should get moving. Regular exercise is linked to retina health. Plus, sufficient exercise along with a balanced diet can help prevent other medical conditions that put your eyes at risk.

Aside from these things, being aware of your family’s health history is another big factor in eye health. Your physician and optometrist can help you check for symptoms that may be signs of known health problems common to your family, and can suggest prevention tips as well as early intervention if you discover there is a problem.

If you notice any changes in your vision—such as haziness, cloudiness, double vision, difficulty seeing at night—see your optometrist right away. A healthy lifestyle, regular checkups, knowing your risk factors, and basic protective measures will help you keep your eyesight clear for as long as possible.
