If you have ever heard of the brand Polaroid, and you remember the lightweight cameras that permitted you to quickly take a photograph and produce a print (images of shifting the impression in the air until it processes and dries one thinks of), then you may possibly know that Polaroid also creates sunglasses that include a polarised contact technology. These are often mistakenly said to be one and the same but nothing may be further from the fact when it comes to a quality, market leading polarised eyewear lens.Nearly all sunglasses producers produce a polarised variation within their range, the expenses involved are higher as this technology is more expensive to produce than a standard contact with UV blocking houses but the advantages are huge. First a lens actually filters a large fraction of reflective glare, this is the single-most important gain of a polarised lens. Reflective light, including sunlight bouncing from your area of water straight into your eyes, is impossible for a non-polarised contact to filter. Even expensive sunglasses that aren't polarised are struggling to filter reflective glare, ergo meaning the individual may squint around reflective surfaces during bright sunny days. If your sunglasses have 100% UV filters then your eyes will still be guarded against all UV injury, actually from reflective light, however reflective hard light will still blast through the lens causing you to squint.This is excatly why it's important to consider spending more on your sunglasses and upgrading to a polarised lens. For brands such as Oakley and Ray-Ban, a polarised contact is more expensive, brands such as Maui Jim have polarised lenses as standard. Other advantages when buying quality polarised sunglasses are plentiful, one example are Maui Jim H407-02 Hookipa sunglasses, these polarised sunglasses come with a array of features including anti-scratch coating, anti-reflective coating inside of the lens to halt light from behind blinding you and even a special waterproofing surface to repel water and oils. These advantages don't sound good on face value but image being on a beach with sunlight behind you as you try and read, the anti reflective lens on the inside of the lens stops you from squinting, the unique waterproofing finish indicates any sun-tan oil that gets on your lens will just wash off without the use of chemical cleaners and the polarised lens will cut all the reflective glare from the sand and sea.Furthermore, Ho'okipa H407-02 sunglasses come with a brand new lens material that allows colours to be bigger and lighter, something that usually never occurs with grey based lenses as generally a grey based lens flattens and dulls colours instead of raising the light.Think long and hard when getting sunglasses, a polarised lens will produce a world of difference to your perspective, cut down on headaches and increase focus as your eyes relax significantly more than they would behind non-polarised lenses.
