The plano (without prescription) Polarized driver lenses in the smart Positano frames managed to make the view ahead clear and bright without overpowering the eyes, while overcast and hazy views somehow looked radiant and sharp.

Ophthalmic Epidemiol 2000 Sep;7(3):159-67 Available from: http://www.ncbi.nlm.nih.gov/pubmed/11035552. Exposure of very young children to UV radiation should be limited. It is important that children wear a sun protective hat to provide some protection to the eyes.

Glare is frequently blamed as the cause of road traffic accidents, but the right pair of sunglasses can prevent it.If you are sunglasses wholesale business, you can request a certificate of conformity or declaration of performancefrom sunglasses factory. It is ideal if you suspect misusing the CE mark. It would give you test results and other information on how the item passed CE requirements. What Do Sunglass Categories Mean? Cancer Council Australia recommends protecting the eyes during sun protection times (when the UV level is 3 or above): Ultraviolet A-Rays.Of all types, it has the least energy but can cause skin cells to age and some indirect damage to the cells’ DNA.

Driving has reviewed and rated some seriously stylish sunglasses for drivers, from leading brands including:You need to know that the percentages shown here are indicative, a variation of 2-3% above or below is acceptable to place a pair of sunglasses in one category or the other. UV Protection is not the same with polarized lenses. Just because a pair of sunglasses have 100% UV protection doesn’t mean it has polarized lenses. Regardless of the brand and style, UV protection is mandatory for all sunglasses. However, not all sunglasses that have UV protection have polarizers. Have a thorough eye examination every two years to find out if you need prescription lenses in your sunglasses. And it's just as important to protect children's eyes from the sun with sunglasses (as soon as you can convince them to keep them on); UV exposure in childhood is related to skin problemslater in life, and it's likely to be much the same for eyes.

These provide high protection against sunglare and good UV protection; they are not suitable for driving at night or under dull light conditions. Lindgren G, Diffey BL, Larkö O. Basal cell carcinoma of the eyelids and solar ultraviolet radiation exposure. Br J Ophthalmol 1998 Dec;82(12):1412-5 Available from: http://www.ncbi.nlm.nih.gov/pubmed/9930273. Polarizers or polarized lenses are extra filters used in some sunglasses. These filters are chemical films added to the layers of the lens construction. Its primary purpose is to boost the sunglasses’ ability to reduce glare from reflected and overhead sunlight. Xtractive lenses differ from Drivewear in that the latter are permanently tinted — in other words, full-time sunglasses — whereas the former are completely clear when not exposed to sunlight. That means they can be worn indoors as well as outdoors by those who require prescription lenses, without the need to switch between sunglasses and standard spectacles. By setting these higher standards and enforcing the requirement of labelling the product, this will only assist to raising consumer awareness about the properties and lens quality of sunglasses. The elements which must now be clearly labelled include:-Exposure to UV radiation over long periods can result in more serious damage to the eyes including squamous cell cancers on the surface of the eye [2] [3] [4] and skin cancer around the eyes [5]. There is a strong evidence that UV exposure is associated with basal cell carcinoma and squamous cell carcinoma of the eyelid, photokeratitis, climatic droplet keratopathy, pterygium, and cortical cataract [6]. However, the evidence of the association between UV exposure and ocular melanoma is limited [7] [8]. There is insufficient evidence to determine whether there is a clear causal link between UV exposure and age-related macular degeneration (AMD) [6] but there does appear to be evidence showing greater sun-light exposure could increase risk. Theoretically this may be more due to effects of visible blue light rather than UV [9] [10]. Although UV radiation is strongly associated with skin cancer, including on the eyelids [2] [11], UV does not appear to be a risk factor for sebaceous carcinoma of the eyelid [12].

Unlike Transitions [reviewed below] and other reactionary lenses, all Serengeti models are sunglasses first and foremost, so they can’t transform from completely clear to opaque but they look much better for it. In fact, they can rival many of the big brands for stylishness. These Category 3 sunglasses are recommended for all types of outdoor activities, such as spending a sunny day out in the country or on the beach. This is also perfect for all types of sports, with the exception of the ones that we will mention below. All of our lenses are Category 3 sunglasses Not all our brands provide this information and in reality almost all brown and grey (or ‘smoke’) lenses are Category 3. Primarily, sports sunglasses categories signify the density of the lens tint and there are five categories in total: The style is deliberately understated. But if you want to jazz them up, there are some pretty vibrant colours for the frames and complimentary mirror-finishes for the lenses – including candy pink or lime green. Category 4 lenses are illegal for use whilst driving and are best avoided unless you require them for extreme exposure scenarios.Category 3 sunglasses are the most common category and provide added protection from UV light. Our standard dark sunglasses tints are within this category, offering 100% UV protection and filtering out 75% of the light. They come in brown, grey and green. These sunglasses are perfect for everyday wear. It’s possible to find very dark glasses that absorb a lot of sunlight but don’t have a good UV filter: this type of sunglasses are commonly found in your everyday supermarkets.
