Why can’t I read my cell phone with my polarized sunglasses?

If you love being outdoors you should know wearing polarized 100%UVA/UVB blocking sunglasses is the smart thing to do. Lens filters on sunglasses that block 100% of UVA & UVB rays will save your eyes from glaucoma, cataract and macular degeneration-causing UV rays. The Polarization filter, on the other hand, will protect your eyes from painful and blinding glare.  However, you might have noticed your cell phone, iPad, Kindle or tablet screen is difficult to see when you are wearing polarized sunglasses. If your sunglasses are polarized (and they should be, for maximum eye protection), your screen might look very dark or completely black when you look at it. Why does this happen?  Most phones have a polarizing filter that helps to cut glare and reflections, ironically to make it easier to see in bright sunlight. The problem is, so … Read More

Polarization. Polarized Lenses.  What does that mean?

By now must of us know we should buy polarized sunglasses but most of us don’t know what polarization really is or does. Polarizing the lenses of sunglasses means a polarizing film has been laminated or cast onto the lenses. A polarized film is made up of special molecules running in horizontal parallel chains. This film acts as a filter, blocking out sun light that bounces off reflective surfaces such as car hoods, water, road surfaces, concrete, light colored or white surfaces, even fog. This reflected light, or glare, is 7 to 10 times brighter than normal daylight.  Polarization reduces glare. Glare is dangerous for several reasons: Glare is reflected UV light and ultraviolet sun rays have been linked to eye diseases like cataracts, macular degeneration, eye cancer, and other diseases. Glare is blinding and can result in accidents especially … Read More

Gardening Tips for Spring

I love gardening because it is one of those projects that can bring instant gratification. I get a lot of satisfaction from weeding the garden, planting a flower bed or growing my own tomatoes. Since it is spring, I am eager to tackle my little patch of nature. This year, I am planting zinnias, marigolds and tomatoes from seed and I’ve learned that the potting mix you use actually makes a difference. There are special mixes for growing seeds. I usually start my seeds in small containers in my kitchen by the window and once they are about 2” tall, I take the containers outdoors for short periods of time so they get acclimatized. After about 1 week, I transplant them to the garden. I plan to spend a lot of time outdoors this spring and I plan to wear … Read More
