|Performance and Sport Sunglasses
The recent boom and the extreme popularity obtained for outdoor sports activities like mountain biking http://www.arsenalfcpro.com/Kids-Chuba-Akpom-Jersey/ ,snowshoeing,
rock climbing,skiing,kayaking http://www.arsenalfcpro.com/Kids-Carl-Jenkinson-Jersey/ ,golfing and in-line skating has motivated the sun glass manufacturers
to design performance-oriented sunglasses.
To meet the demands of the casual and competitive sportsperson, much study and growth has been done by the
sun wear manufacturers as to how they could create the best sunglasses for various activities,
requirements and environments.The results:lightweight,flexible and durable materials http://www.arsenalfcpro.com/Kids-Calum-Chambers-Jersey/ ,no-slip components
that do not fail in the heat of the moment, and of course lenses were introduced.
Lenses, perhaps the main significant aspect effective for sports sun wear has optical quality and image
enhancement. These lenses are now accessible in many colors such as brown, green http://www.arsenalfcpro.com/Kids-Blank-Jersey/ , gray, yellow,
orange, etc... that are chiefly effective in certain situations.
Polycarbonate lenses are tremendously popular for its super muscular and impact-resistant quality that
particularly attracts many people involved in sports.
Polarized lenses are also in great demand as they decrease glare produced on smooth surfaces such as
water or a field of snow. Polarized lenses are highly effective sports lenses
that work effectively with both the contradictory sports activities like the downhill to mogul skiing.
Glass lenses have great visual quality. Hence they are used as casual sunglasses and for golfing.
Even though glass lenses have such great visual quality they are rarely used as sports eyewear
because many people concerned in extreme sports shy away from glasses lenses for the possibility
of shattering upon impact.
What's Your Sport?
One major trend that has hit the sports eyewear arena lately is sports-specific sun wear.Frames and
lenses are now accessible that are targeted exclusively to the golfer http://www.arsenalfcpro.com/Kids-Bernd-Leno-Jersey/ ,the cyclist,the boater,the rock
climber and so on. This accessibility and specialization has fashioned great consumer interest
and hence has increased sales in sports eyewear.
If you are the Jack of all sports, there is also a selection of multipurpose sports sunglasses
available for you in the market. Changeable lens systems are also obtainable.
Another tendency in sports eyewear that has made consumers much more conscious of the brands
and the products out there are the product endorsements and sponsorships by well-known professional
athletes. Kobe Bryant of the Los Angeles Lakers http://www.arsenalfcpro.com/Kids-Alexandre-Lacazette-Jersey/ ,John McEnroe of pro tennis fame,
PGA golfer David Ledbetter,Missy Giove,a top mountain biker http://www.arsenalfcpro.com/Kids-Alex-Iwobi-Jersey/ ,pro surfer Laird Hamilton,and even
Olympic skier Johnny Moseley all have support deals with chief sports eyewear lines.
Lutein for macular degeneration prevention Published: 21.06.2010 | Author: udtekadapter | Category: Acne
As a component of a healthy retina, lutein has been the subject in many researches during the past several decades. Most of these study groups have focused on the link between lutein and macular degeneration. Macular degeneration now affects about 1.2 million Americans. And there are currently no effective treatments for this disease. As a result, macular degeneration prevention comes into the most important.
Macular degeneration is believed to be a lifestyle-related disease. Both eating habits and a couple of lifestyle factors may contribute to this eye disease. Moreover http://www.arsenalfcpro.com/Kids-Ainsley-Maitland-Niles-Jersey/ , generic factors are also one of the major contributors, in which case the disease may be inevitable and more serious. Since lutein is a major component of the retina, this nutrient is considered to be close related with macular degeneration.
Macula is exactly a tiny spot within the retina and is responsible for central vision, which is the most important part of the overall vision. Dry macular degeneration is the main target of those studies focusing on lutein as well as other antioxidants. These study groups want to reach an exact conclusion about the benefits of lutein to macular degeneration prevention.
In fact http://www.arsenalfcpro.com/Kids-Aaron-Ramsey-Jersey/ , there is proven evidence showing that lower concentration of both lutein and zeaxanthin in the retinas is closely associated with macular degeneration. But evidence linking low levels of lutein alone and the disease is still absent. This way of nutrient concentration measurement has been developed recently. Ophthalmologists may be able to measure the antioxidant concentration in their offices in the future.
The strongest connection between lutein and macular degeneration came from a six-year study by the National Eye Institute in Maryland. Lutein is believed by researchers of this study to protect against blindness. But the formula they used also contained zeaxanthin.
In addition, some other studies also recommend fish oil, the antioxidant Astaxanthin and other beneficial foods for early intervention of macular degeneration. Fish, fruit and vegetable are decisive to a healthy body.
