Now, I realize it’s the end of January – and the days are still pretty short. Depending on where you live, you might be wondering why I’ve chosen this time of year to talk about protecting your eyes from the sun.

It is specifically because it’s winter that I’m sending you this issue, actually. To clear up a common misconception many people have about when the sun is dangerous – and when it isn’t.

Your eyes are fragile. And unlike other parts of your body, damage done to this most-sensitive area can be irreversible. Your eye’s lens doesn’t repair itself when damaged, and cells and proteins that are lost may never be replaced.

Open your arteries, improve blood flow for a new health miracle...

Did you know your circulatory system has over 60,000 miles of arteries, veins and other blood vessels, if stretched end to end?

But as you age, your blood vessels undergo changes, which may cause them to stiffen, thicken and get clogged.

GOOD NEWS! Doctors have now identified a “Miracle Molecule” inside your arteries that helps OPEN your arteries and IMPROVE blood flow.

It’s what Dr. Valentin Fuster calls it, "One of the most important discoveries in the history of cardiovascular medicine."To you, that means...

  • Healthy blood pressure
  • Sharper mind and memory
  • Skyrocketing energy and muscular strength
  • Increased pleasure and passion in the bedroom
  • Improved circulation to every cell and organ in your body

Go here to discover a new natural way to significantly boost the levels of this miracle molecule in YOUR body NOW!

This is one part of your body you truly can’t afford to neglect. Taking supplements formulated for your eye health is one important step. But there’s another form of protection that you can’t buy in a bottle…

Because exposure to the sun is a critical way to get Vitamin D – one of the most essential vitamins for your immune system – I’m all in favor of soaking up a little sun every day. And yes, you should take reasonable precautions to protect your skin, but I am not a big fan of excessive sunblock if it also blocks you from absorbing the good of the sun.

When it comes to your eyes, however, my tune changes dramatically. Wearing protective eyewear, even in winter and cloudy weather, is essential. Choosing the right protection means understanding why you need it, and knowing what to look for when you buy shades.

There are two types of rays to watch out for – blue rays that you can see, and the UV rays that are invisible to you. Each one requires a certain type of protection. And each one wreaks a different kind of havoc on your eyes.

This Nutrient is 400% More Powerful than Resveratrol!
Support a Healthy Heart, Blood Pressure,
Cholesterol, Fat-Burning, and More!

New research supported by the National Institutes of Health revealed a chemical flaw in this near-miraculous nutrient. Human studies show we just can't absorb it. No matter how much you take...you may as well be flushing it down the toilet!

But the benefits of resveratrol – and the amazing promise of genetic rewriting – were too incredible to ignore. That's why researchers kept looking… until they found a natural resveratrol "cousin."

  • 400% BETTER absorbed than resveratrol
  • Infuses your body with energy and superior anti-aging benefits
  • Supports healthy cholesterol, blood pressure, and blood sugar.
  • Fights inflammation
  • Gives you a metabolic edge
  • Switches on "life extension" genes
  • It could even make you smarter!

Use it today to help protect your heart. Discover how it can help you become slimmer and more vital...and bring your cholesterol, blood pressure, and blood sugar under control naturally.

UV Rays:
For the fragile mechanisms of your eye, UV rays have no positive benefits whatsoever, none.  Which means wearing protective lenses whenever you are outside in the daytime is a must… even on a cloudy day, as UV rays are not filtered by clouds. Over time, exposure to UV rays can cause cataracts.

There are three types of UV rays:

  • UVA rays, which have long wavelengths and can pass through glass. While these are not the most harmful of the three types, it is still recommended that your eyewear carries protection against them.
  • UVB rays are the most harmful to your eyes, although they don’t go through glass. Protecting against these rays is critical during outdoor activities.
  • UVC rays are the most intense of the three. Fortunately, they are blocked by the Earth’s atmosphere.

Glare and reflections can also magnify and intensify the exposure, which means you need protection when swimming, skiing or walking along the beach in particular. And of course, if you use tanning beds or sunlamps, live at a high altitude or near the equator, or are on any medications that make you more sensitive to light, you’ll need the highest levels of protection available.

Blue Rays:
Unlike UV rays, blue rays are visible – they are what make the sky blue! But they also cause a photochemical reaction that produces free radicals in your rods, cones and RPE (Retinal Pigment Epithelium), a layer of cells that protects the retina and when damaged, can cause macular degeneration.

The darker your eye color, the more natural protection you have against blue rays. The lighter your eyes, the more protection you need. This is because melanin – the substance giving eyes their color – traps the light rays before they can damage the macula. In fact, blue eyes transmit as much as 100 times as much light to the back of the eyes as dark colored eyes do!

Since UV rays are invisible, so is UV protection. But blue ray blockers are visible as a yellow or amber tint that alters the appearance of blue and green colors. But the tint doesn’t affect the way other colors appear. In fact, blue ray blockers can improve color contrast, and have become popular as sports glasses because they improve outdoor vision and reduce glare more effectively than UV protection alone.

While there is some controversy over the hazard vs. benefit of blue light, science is coming down on the side of caution. However, if you have conditions such as Seasonal Affective Disorder (SAD) or bipolar disorder, you might want to check with your physician or an ophthalmologist to get a more specific recommendation.

The best way to protect your eyes is to wear sunglasses. However, not all sunglasses will provide you with equal protection from UV and blue light rays. For maximum protection, you should look for sunglasses that:

  • Block 99-100% of UVA and UVB rays
  • Block blue light rays
  • Contain large lenses that fit close to your eyes

You don’t necessarily need brand name, big bucks lenses to get this protection. But glasses that offer protection should be clearly marked when purchased. If you purchase a used or vintage pair of frames – or you’ve had your sunglasses so long and you want to double check them – you can take them to just about any optical store and ask them to tell you. Most will have a UV meter and can let you know in minutes, free of charge.

Please don’t compromise protection for style. Frames should be large enough to offer full protection, preferably wrap-around to keep rays from leaking around the edges.

And finally, if you wear contact lenses, check with your optometrist or optician about the protection in the lenses, and what you need to augment with to achieve optimal protection.
