Now that summer is over, the heat strokes and the pinching warmth of the sun has settled, you may possibly think the time has come to give your sunglasses a rest until next year. Irrespective of fact, what season, the peeper protectors must necessarily keep the harmful ultra-violet radiations from making its course to the eyes and triggering short or long term health conditions like burning sensation, hypersensitivity to light, cataracts, and even eye cancer. But surely such conditions can be easily avoided by following a simple habit of wearing eco-friendly sunglasses.
In reference to the poll conducted by some of the renowned sunglass companies, it was found that only 75% of the adults wore eye-wear but not specifically eco-friendly sun-glasses whenever they stepped outside, but through an observational study, it was found that only 63% of adults actually wore eye-wears when outdoor. Statically only 40-45% of the adults wore shades while driving, and apparently only 12 % wore shades as a measure to protect from UV rays.
Why are sun glasses so important?
Even though the sun is almost 93 million miles away from Mother Earth, its rays can channelize significant health and visual dangers. The principal threat posed by the sun is in the form of Ultra Violet radiations. You possibly understand the ill-effects of UV rays to your skin that is why you apply sunscreen. May be you don’t know how harmful UV rays can be to your eyes, vision; that is why you don’t consider sunglasses important. Sunglasses or shades can help be helpful for eyes in 5 (five) principal ways:
· Protects against damage by filtering the light susceptible to eyes.
· Reduces glare
· Protection against blue-light
· Adaption to dark light
· Comfortable vision
Eyewear are available in a wide-variety depending on the material type, from classic to eco-friendly ones. The material of eyewear defines its weight, resilience and flexibility. It is often said eco-friendly materials are better than artificial n synthetic stuff, the same applies for eco-friendly sunglasses.
Speaking of ecological alternatives, the eco-friendly sunglasses broadly classified into 3 major categories:
· Biomaterial Material
· Recycled Material
These are generally prepared from bio-materials to produce a greener material. The typical constituent is castor oil seed blended with polycarbonates. The foremost benefit of biomaterial frame is that it is an eco-friendly sunglass which maintains the properties of original plastic. Lesser availability id the only shortcoming.
Isn’t the idea of using recycled material for crafting shades simply amazing? Making use of the material which no longer serves their original purpose to fashion sunglasses is a great way to go. Even though, we are recycling, the weaknesses of the original material still exists.
Materials like wood or horn can be used to fashion frames. Usually, to craft frames from these materials need special kills, as it demands hand-work not the machine manufacturing. The benefits of such type are, eco-friendly and unique –n- exquisite. Whereas, the shortcomings of using wood or horn to craft eyewear frames are, inelastic, fragile and badly resistant to water.
The way frames are very much considerable in crafting eco-friendly sunglasses, so are the lenses. The most popular types of lenses are clip-on, mirrored, photo-chromatic, polarizing and gradient.
