Although very often we tend to consider eyewear as a form of decoration, sunglasses are first and foremost a protection of the delicate eye system from the impact of the ultraviolets. Special vision problems prevent lots of people from being able to wear sunglasses, which makes them even more exposed to various other eye health problems. Hyperopia, myopia and astigmatism are just a few examples here. The solution for such cases is to be found in prescription sunglasses designed to match exactly the same features of the regular glasses but with ultraviolet protection. The UVB rays cause sunburn while the UVA rays get absorbed by the human eye lens.

Prescription sunglasses represent a combination of regular glasses with a dark lens design. There are different kinds of lenses used for prescription sunglasses, and here we can count polarized lenses, anti-reflective lenses, blue blockers, photochromic lenses and gradient lenses. It is important to mention here, before going on with the description of prescription sunglasses, that you can only order this kind of eyewear based on an ophthalmologist’s recommendation and after careful medical examination. Total protection against the UVAs and the UVBs should be covered at optimal parameters, due to the fact that people with eye surgery should not be exposed to powerful radiation.

Some prescription sunglasses rely on a wraparound design that prevents the UV rays from entering from the sides. The frame makes such protection possible, because a too thin or small frame design will be insufficient. As for the glare, not only prescription sunglasses but most sunglasses in general have a special anti-reflective coating that ensures superior reflexion of the light. Mirror-coated lenses are sometimes used for the same purpose of reducing glare. One special mention here is that the design of the prescription glasses also depends on the stage of the eye health condition.

For instance, people who suffer from advanced myopia may require very thick lenses, which could be incompatible with most of the frames. There are other situations when two or more health problems are present, as one person could suffer from both astigmatism and myopia, to give just an example. Solutions may be available, but only a specialist will be able to tell you which is the best for you. Moreover, price awareness is another important element given the fact that prescription sunglasses will always be more expensive, as the number of specialists who can design them is smaller too.

Different from casual eyewear, sports sunglasses are practical items that incorporate special technical features. While style is just as important as safety design in regular sunglasses, sports sunglasses have a dominant, undeniable functional side. Usually designed to also match fashion trends, such items impress by the way they serve the user outdoors. There has to be maximum visibility, full blockage of harmful radiation and protection against debris as the main expectations you can formulate in relation with sports sunglasses. Golf, cycling, extreme sports and even hiking require the use of special protective sunglasses to stop the eye contact with the UV rays.

There are even sports sunglasses that combine the casual street style with the extreme sports requirements. Polarized for a perfect anti-glare feature, such items will be comfortable and actually priceless when skiing, snowboarding or enjoying any other sport. Self-locking screws, face hugging contours and high precision hinges, these are indeed features that you’ll only encounter with certain high quality sports sunglasses. For increased durability and resistance to impact, sports sunglasses usually have polycarbonate lenses and nylon frames. The breakage hazard makes glass incompatible with sports activities.

Just as it happens with clothes and accessories, sunglasses are subject to constant fashion changes. Anyone who is keen on good looks knows that men’s sunglasses could reflect personality and individual style.Some men will wear a good pair of sunglasses for two or more years, while others will consider updating their accessories every year. Styles like sports, shields, aviators, the retro style or wraparounds are the favorite models when it comes to men’s sunglasses. Available from lots of brand companies and in different lens and frame colors, 2009 trends revolve around these designs.

The 80s or 90s look is revived in some retro men’s sunglasses. Designers like Ray Ban or Tom Ford make such old-school choices really valuable. Men’s sunglasses stand out less than women’s and people definitely prefer them that way. A man can be comfortable and elegant with quality sunglasses that don’t get immediate attention by design. Besides the retro option, aviators make a popular choice too, and they are included in many lines of men’s sunglasses. Have a look at the online collections and you’ll see what selection is about.
