Risks of blue light exposure have become a topic of discussion in recent years. More eyecare professionals and scientists are studying the effects of blue light to assess the effects of relying on blue light for so much of our lighting.

It’s hard to say for sure how much added blue light exposure may lead to additional cases of degenerative eye health problems like macular degeneration. Plus, there is some evidence that overexposure to high-energy blue light can cause side effects such as sleep disturbances, eye strain, and headaches. With this in mind, how can you reduce your exposure, inside and out?

Inside
• Lower the brightness of your electronic screens, especially at night, but make sure you are not straining to see the words if you’re reading.
• Take frequent breaks while working at a computer. Regardless of blue light exposure, Computer Vision Syndrome is another problem you may face, and taking breaks to relax your eyes will help.
• Stop using your devices at least a couple hours before bed. Unplug and read a book instead, which will give your eyes something easy to focus on and help you wind down for good sleep.
• Adjust your distance. Viewing a bright screen up close is fatiguing. Make sure to set your computer monitor and television at a comfortable distance, and don’t hold handheld devices too close to your eyes. You can adjust text size if reading a device at arm’s length is difficult.
• Opt for non-glare lenses. Non-glare or anti-reflective treatments on your lenses will help reduce bright lights affecting your eyes.

Outside
• Wear sunglasses. Sunglasses that are an appropriate darkness and block 99-100% of UVA-UVB rays are the best protection for your eyes.
• Consider polarized lenses, too. Polarization cuts harsh glares that bounce off of water and other surfaces.
• Don’t forget a hat! In especially bright outdoor settings a hat will help block bright light from above, even if your eyes are protected from the front.

Many medical professionals are aware of the benefits of adding healthy oils to our diets. Most of the fats that are essential for a healthy heart, skin, brain, and other systems come from things like fish, nuts, seeds, and vegetables. Doctors will sometimes prescribe fish oil or flaxseed oil to help improve someone’s health, but we are learning more and more about how these beneficial oils can help more than previously thought. In the case of your eyes, certain oils may aid in treatment of dry eyes.
Vision Benefits of Flaxseed and Fish Oil

Fish oil and flaxseed oil are beneficial because of the omega-3 fatty acids they include. These materials are needed to support optimal health. Flaxseed oil contains high levels of alpha-linolenic acid (ALA), an omega-3 fatty acid. ALA is converted into two different omega-3 fatty acids during digestion. These acids are called EPA and DHA and they protect cell membranes all over the body.

By adding flaxseed oil or fish oil to your diet, you may be protecting against dry eyes. These items appear to reduce dry eye symptoms, and can be used with or without eye drops to alleviate some aspects of dry eyes. Many eye doctors are recommending fish oil or flaxseed oil as part of an overall plan to treat dry eyes, or to prevent the onset or progression of symptoms.

Symptoms of dry eyes include:

• Chronic dryness
• Burning
• Stinging
• Redness
• Eye fatigue
• Sore eyes
• Light sensitivity
• Blurred vision

How to Start Taking Flaxseed and Fish Oil
If you’re looking for how to get these substances into your diet, keep in mind that many kinds of fish are high in these oils. Look for things like salmon, sardines, tilapia, and shrimp. For people who don’t like fish, or want other options, fish oil supplements are usually pretty inexpensive and easy to come by. You may ask a pharmacist for suggestions on which over the counter versions are best.

The downside of fish oil is that sometimes people will get a fishy aftertaste from the supplements. A great alternative is flaxseed oil. These supplements are readily available as well, and will provide similar benefits. Just be sure to find a brand that is cold pressed and remember to keep it refrigerated for freshness and optimal nutrient content (benefits of flaxseed oil are reduced by exposure to oxygen, light, and higher temperatures).

Flaxseed oil can get a little pricy, but you can buy flaxseeds and grind them in a coffee grinder before adding them to your diet. Use them immediately to get the full benefits!
Other Benefits

These fatty acids may help reduce your risk for several other health problems. The benefits include:
• Reduced risk of macular degeneration
• Reduced risk of cataracts
• Increased cardiovascular function
• Lower risk of heart disease
• Help maintain healthy weight

It’s the end of the week and you’ve only got a few hours left before the weekend. As you try to finish the last of your tasks, you find yourself unable to focus—not just mentally, but physically. You have trouble seeing the screen in front of you. Maybe your vision is blurry or your eyes start to burn. These are symptoms of computer vision syndrome.

Computer vision syndrome is simply the name given to a group of symptoms and problems associated with overuse of computers and strained eyes from excessive computer use. It’s becoming a more common problem as more people work in offices behind computers, and rely on tablets or smartphones instead of paper. These devices have helped make us more productive with faster communication and easier recordkeeping, but the reliance on electronic screens in front of our faces can also be a problem for our eyes.

There are many things you can do to prevent or relieve the symptoms of computer vision syndrome. If you wear glasses, make sure your prescription is up to date. If you do not wear glasses (or if you wear contact lenses that you’re sure are an appropriate prescription for you) yet still experience discomfort while on a computer, computer glasses may be what you’re looking for.

Computer glasses are different than traditional eyeglasses or reading glasses. Due to such a short distance between your eyes and the computer screen, distance eyeglasses and reading eyeglasses may not be as effective for your eyes. They’re not necessarily meant for focusing for longer periods on the intermediate zone of vision. Made specially for viewing a computer screen, computer glasses help you focus on this very zone where your monitor sits, making daily use much more comfortable.

Without a proper prescription or an aid like computer glasses, those experiencing blurred vision may end up leaning forward in order to see. This can negatively affect posture and cause even more strain on your body. In addition to eye health, it’s very important to have a healthy workspace and comfortable posture.

Because computer glasses have a modified lens, they give you the most comfortable view of your computer screen. For maximum viewing quality, the lenses should include anti-reflective coating. Tinted computer lenses are also recommended in order to block out blue light that is emitted from computer screens.

With a decrease in eyestrain, and no more blurred vision or headaches, it’s obvious how much computer glasses can help make you feel better and more productive. Ask your eye care professional if you’re interested in learning more about computer glasses and how they can help prevent computer vision syndrome.

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. Children should 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 family eye care professional 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.
