How To Protect Your Eyes During the April 8th Solar Eclipse

On April 8, a total solar eclipse will cross North America, the last time a total solar eclipse will be viewable from the continent until 2033. A total solar eclipse happens when the moon passes between the earth and the sun, temporarily blocking the view of the sun from a part of the earth. It’s an incredible and rare sight to behold — but looking at a total or partial eclipse can severely and permanently damage your eyes and eyesight if not done with proper protection. 

The major cities inside the path of the total eclipse are Mazatlan, Torreon, San Antonio, Austin, Dallas, Fort Worth, Indianapolis, Cleveland, Buffalo, Rochester, Syracuse, and Montreal. However a partial solar eclipse will be visible throughout most of the US — even observing a partial solar eclipse unprotected can damage your vision.

North America will experience totality again in 2033, when the next total eclipse crosses Alaska. In 2044, another total solar eclipse will occur and be visible in multiple continental U.S. states, including Montana and North Dakota. 

How to protect your eyes when watching a solar eclipse

  • To protect your eyes during an eclipse, you need special glasses. Never use sunglasses, as they do not offer proper protection. Make sure they meet safety requirements and are manufactured with the ISO 12312-2 standard. Look for ISO standard labeling when looking for solar eclipse glasses and purchase them from a trusted source.
  • Wear your solar eclipse glasses at all times when watching an annular or partial solar eclipse.
  • Make sure they fit well and cover both of your eyes. Avoid glasses that are too wide or large and could fall off your face.
  • Make sure they don’t have any scratches or other signs of wear and tear. If the glasses are damaged, do not use them, they are not safe to use.
  • Be sure to read and follow any directions included with your eclipse glasses.

How NOT to watch a solar eclipse

  • NEVER look at the sun directly.
  • Do NOT use your smartphone: Watching a solar eclipse on your smartphone camera can put you at risk of accidentally looking at the sun when trying to line up your camera. It could possibly also damage your smartphone camera. Don’t take the risk.
  • Do NOT use your camera viewfinder: Never look at a solar eclipse through the optical viewfinder of a camera. It can damage your eyes in the same way as looking directly at it.
  • Do NOT use unsafe filters: Unless specifically designed for viewing a solar eclipse, no filter is safe to use with any optical device (telescopes, binoculars, etc). All color film, black-and-white film that contains no silver, photographic negatives with images on them (x-rays and snapshots), smoked glass, sunglasses (single or multiple pairs), photographic neutral density filters and polarizing filters are unsafe filters to watch a solar eclipse. Also, solar filters designed for eyepieces that come with inexpensive telescopes are also unsafe. All of these items can increase your risk of damaging your eyes.

Save Your Vision Month –

Save Your Vision Month is here.

We at DEF remind you to prioritize your eyes in 2024

In honor of Save Your Vision Month, here are some everyday things you can control to help “Save Your Vision”.

  • Enjoy a cup of tea –Green tea contains antioxidants, like vitamins C and E, lutein, and zeaxanthin that help protect against AMD and cataracts. It is it hydrating, helping you produce tears.
  • Take time to blink – On an average you blink about 15 – 20 times a minute. However, that rate drops by half when viewing text on a screen. Try using the 20/20/20 rule when staring at a screen: Every 20 minutes, look 20 feet away for 20 seconds so you can blink naturally and give your eyes time to relax.
  • Wear sunglasses and a hat – Exposure to ultraviolet (UV) rays can deteriorate vision over time and can lead to cataracts and possibly age-related macular degeneration (AMD). The American Optometric Association recommends sunglasses that block at least 99 percent of UVA and UVB radiation and that screen out 75 – 90% of visible light. And if you plan to spend a lot of time outdoors, it’s a good idea to get sunglasses with lenses that are polarized, which means that they’ve been treated to reduce glare. We suggest wearing a large brimmed hat to further protect your eyes.
  • Increase the seafood in your diet – Omega-3 fatty acids have been shown to bolster heart and brain health, as well as decrease your risk of eye disease. Studies show consuming omega-3 fatty acids, whether in foods you eat or in a supplement. It may help reduce your risk of developing macular degeneration. Research also shows not only can omega-3 fatty acids help reduce your risk of developing dry eyes, but it may also help treat bothersome symptoms as well.
  • Eat a rainbow – Eating a full rainbow of fruits and vegetables regularly helps give your body the nutrients it needs. In addition to fiber, vitamins and minerals, naturally colored foods contain what are known as phytochemicals, which are disease-fighting substances that also give fruits and vegetable their array of colors. Star nutrients are lutein and zeaxanthin—pigments found in such foods as dark, leafy greens, broccoli, zucchini, peas, and Brussels sprouts.  Also important are antioxidants found in red foods such as strawberries, cherries, red peppers and raspberries, orange foods have beta-carotene and include carrots, pumpkins, sweet potatoes and yams.
  • Use digital screens at a safe distance – The brightness and glare from computers, tablets, smartphones and televisions can lead to eyestrain after prolonged use. Recent studies have also shown ill-effects from the UV rays from these devices. Symptoms can include headaches, blurred vision, dry or red eyes and difficulty refocusing. Experts recommend keeping the computer screen at least an arm’s length away and that you hold a handheld device at least 16 inches from your eyes.
  • Contact lens solutions serve a purpose –The most harmful but common problem is moistening contacts with saliva instead of saline solution. Proper contact lens care is important for keeping and free from infection.
  • Make-up makeover – Replace tubes of mascara after three months, as it is a breeding ground for bacteria. Sharpen liner pencils regularly and while it is okay to line the base of your lashes, using the liner inside the lash line can block oil glands. Replace eye shadows yearly and don’t share your eye cosmetics.
  • Use protective goggles – According to studies nearly half of eye injuries happen at home. These injuries occur when protective eyewear is not used or when the incorrect protective eyewear is used and an exposure occurs from around or under the protective eye equipment.  Sports activities are another cause of eye injuries, from contact sports to sports that use balls that could catch you unaware.  When snowboarding or skiing remember to protect your eyes from the sun and wind with tinted goggles that have UV protection.
  • Have a yearly eye exam – Even if you don’t wear corrective lenses, adults should get a comprehensive eye exam (which includes dilating your pupils with drops) by age 40. After that a yearly eye exam is recommended to keep your eyes healthy and catch any changes in your eyes that may be indicators of eye disease. If you have a family history of glaucoma or age-related macular degeneration, or you have diabetes, you are at a higher risk for vision-related issues and your doctor may elect to see you more often. If you have symptoms such as persistent pain inside or behind your eyes, redness, or gradual loss of vision, make an appointment with your doctor immediately.
