The Different Categories of Sunglasses

12 Jul 2018

All sunglasses come in categories, but how are we mere mortals expected to know what category to choose?  Well we have made it simple for you and given you a chart which details which category is right for you.

Not only do we have the problem of 'categories' but we also need to know if we should purchase polarized or non-polarized - so much choice!  Well here is a little something to help you in this direction as well. Polarized or Non-Polarized that is the question!
 So just what is the difference and which is the best for you? Polarized sunglasses have a filter that blocks certain type of light whereas non-polarized are designed to filter all light and can appear darker. Polarized lenses are beneficial to activities that require a reduction of glare from horizontal surfaces, for instance driving, playing sport and fishing but there are activities when polarized lenses may be unadvisable, such as skiing and when using LCD screens and GPS systems as they can reduce the visibility of the latter two. For this reason airline pilots do not have polarized lenses.
 The most important factor of sunglasses is to make sure they have 100% UVA & UVB protection, which nearly all polarized do have, but you will always find this with the better quality sunglasses even if they are non-polarized. So next time you are choosing a new pair of sunglasses, don't forget to ask about the UV protection and do not settle for anything less than 100%. Yorkshire Eyewear have a great selection in their Knaresborough branch and are giving up to 50% on certain makes.
