The only reasons anyone would actively seek out a pair of designer shades are for the look and the quality, with the design a particularly influential factor. It is tempting to think that anyone can spot a genuine designer pair of sunglasses at one glance, but this is not actually the case. For most people, it is the insignia that identifies the brand, but unfortunately there is a wide variety of fake glasses available with the insignia simple glued on. The first step to take when making a choice of designer shades or glasses is to only go to reputable opticians, such as a high street shop or online store that is clearly legitimate. While shops on the high street are easy to recognise as legitimate, online stores must be checked out. They should be open in their tone, willingly providing an office address and phone number, which one should call. Also, look for the Comodo sign on their site, which provides internet security software, which means a transaction is protected. Once happy with the choice of vendor, there are other aspects that should be addressed. First and foremost is making sure that the shades in question provide the type of protection that is expected from a brand name. Protection is, after all, the key purpose of shades so while the frame and lenses may look great, if the pair is not a genuine designer brand they will not benefit the eyes at all. There is one key threat to the eye that needs to be dealt with, namely ultraviolet rays. These UV rays are made up of UVA, UVB and UVC rays, with UVA and UVB arguably the most damaging. UVB are believed to lead to the development of cataracts in the eye, as well as formations of pterygium and pinguecula. UVA, meanwhile, has been linked to the development of skin cancer, liver spots and aged skin, particularly around the eyes. Of course, direct sunlight to the eye can result in blindness, though this is rarely a problem in everyday life. However, ensuring that the highest level of protection from dangerous elements of UV light is essential, which is why lenses providing not less than 99 percent protection is necessary. There are other lens options available, that are more related to convenience and style than to protection. Many designer names provide sunglasses with prescription lenses. This is highly beneficial for the wearer because it means there is no need to change glasses when the situation requires one to read or concentrate more closely on something, like driving. Also possible are photochromatic lenses. These have a photochromatic coating on them that reacts with sunlight and actually darkens; turning what otherwise appears as reading glasses into sunglasses. The lenses are UV protected; thereby ensuring the eyesight of the wearer is protected as well as enhanced. Polarised lenses are also popular options found in designer sunglasses. They are highly effective in reducing the glare that can be caused by sunlight reflecting off shiny surfaces, such as water, glass or metal. This type of indirect sunlight can be just as uncomfortable as direct light to the eye, but principally is dangerous because of the risk of accident.
