A few weeks ago we published a blog about how important it is for our children to spend time outdoors to prevent myopia. ‎

Being outdoors is great for helping to prevent nearsightedness and for exercising our eye focusing muscles, but you may wonder what else you need to do to make sure your child’s eyes stay healthy through the summer.

A few things come to mind.  It has become very common practice to never let our children leave the house with out sun protection: Sunblock, hats, UV blocking clothes and bathing suits. But, what is less common is remembering sunglasses for UV protection for the eyes.  Kids playing outdoors in the sun are exposing the lenses of their eyes and their retinas to harmful UV radiation.  Additionally, their lenses are so young that they do not block UV as well as adult lenses thus sending more UV to the retina.  UV damage to the lens and retina can by a cause of early cataracts and Macular Degeneration.  When buying sunglasses for kids, make sure that they are UV blocking and polarized if possible to reduce glare when around water. More information about children and sunglasses can also be found here.

Next, swim goggles are a good idea for the pool to help keep chlorine out of the eyes.  Chlorine can cause redness, burning, and blurry vision as well.  An added bonus would be swim goggles with a little tint or UV protection as well. If your child experiences these symptoms after playing in the pool, ask your eye doctor what eye drops are right to use to help.

Lastly, the use of sports goggles for eye protection during sports activities is also a must for eye injury prevention while playing soccer, baseball and any other outdoor sports.  For more information about preventing eye injury this summer, here is another great resource.

Enjoy your summer, enjoy the outdoors and the sunshine and stay eye healthy and safe!

Tis’ the season to go skiing and snowboarding.  Ski resorts all over the state are opening this month.  It is a well-known fact that spending time outdoors is healthy for not only your body, but your eyes too.  So get ready, get set, and go!  But before you swish down the mountain, ask yourself if you have taken the necessary steps in protecting your eyes from developing snow blindness – a specific form of something called Photokeratitis or Ultraviolet Keratitis.

Snow blindness can be thought of as a really bad sunburn of your eyes (cornea and conjunctiva).  It is caused by exposure of your unprotected eyes to natural sunlight that is reflected off of the snow or ice.  With just the right mix of high altitude and freshly packed snow, your eyes may be subjected to as much as 80% of UV radiation damage in a very short period of time.

After exposure to ultraviolet (UV) radiation, the white part of your eyes (conjunctiva) may look extremely red and the clear covering of your eyes (cornea) may take on a glassy appearance.

Overall, your eyes will not be feeling too great.  With every blink, you may experience unrelenting pain, intense tearing, sandy and gritty feeling, eyelid twitching, discomfort with bright lights and a natural tendency to want to blink more rapidly or shut your eyes tight.  Your vision may be reduced to varying degrees.

The best way to prevent snow blindness is to wear UV-blocking sunglasses or goggles that only allow a certain amount of visible light through. Also, remember to don that protective eyewear whether it is a sunny or a gloomy, overcast day – UV rays can reach your eyes under any condition.

In the event that you forget to bring your sunglasses or you lose them on the way down the slopes and sustain subsequent sun damage to your eyes, your friendly optometrist can promptly treat your symptoms and provide comfort and relief.

While snow blindness is a one form of Photokeratitis,  there are also other forms of which you should be aware, including artificial lights from suntanning beds, electric sparks, halogen desk lamps, flood lights, and arc welding (welder’s flash, arc eye, flash burn) just to name a few.  The prevention is the same.  Wear your UV-blocking sunglasses or goggles to not only look stylin’, but to preserve the health of your eyes and sight.

See you on the slopes!

Quick Tips for Sports Vision

To do well in sports, you need to have your eyes working at the top of their game. Here are a few quick tips to help you or your athlete perform better:

  • Make sure you have a proper prescription on, whether it is contact lenses or glasses. Having your vision dialed in correctly is the most important step to get your eyes working their best.
  • Be sure to protect your eyes! Polycarbonate or other protective plastic lenses can keep your eyes protected while you play as well as keeping dust or wind from getting in your eyes while you play the sports you love. This table can help you determine which types of eye protection are best for the sport you play. (http://www.allaboutvision.com/sportsvision/eyewear.htm )

  • Consider color filters for your field of play. Certain types of filters or tints can increase your contrast sensitivity and thereby increase your reaction times. Allaboutvision.com has an excellent table for different tints to help in different sports (http://www.allaboutvision.com/sportsvision/lens-tints-chart.htm ). Remember, the faster you can recognize that curve ball, the easier it will be to adjust your swing!

Summer & your eyes: Swimming pools

Yay – Summer is officially here!

School is out and we finally get to spend some serious time in the pool. But before you jump in, here are a few quick safety tips for you and your eyes:

  • The pH of our eyes is 7.2, so can you guess what the recommended pH is for your pool? (hint: it’s 7.2!) Remember to check the pH levels in your pool at least once or twice a week and try to keep it in the range of 7.0-7.6.
  • Chemical conjunctivitis or red eyes can occur due to chlorine exposure in swimming pools. Having a little after a day in the pool is okay, but if it persists into the next day or if it seems to be getting worse, call your optometrist and ask to have your eyes checked that same day.
  • As a general rule, contact lenses should never be worn in the pool. Doing so puts you at risk for a variety of possible infections, including a fungal infection called Fusarium keratitis that is difficult to treat and can lead to permanent blindness. (The only exclusion to this rule is for my daily disposable contact lens patients under the strict condition that their contacts are thrown out as soon as they leave the pool.)
  • Prescription goggles are available and can be fairly inexpensive! If you rely on your glasses to see, talk to your optometrist about prescription goggles for use in the pool.
  • And if you plan to be hanging out around the pool this summer, remember that sunglasses are just as important for protecting your eyes as sunblock is for protecting your skin. Make sure yours have UVA and UVB protection.

Have safe and fun summer!
