It goes without saying that UV protection is the number one quality criterion for a good pair of sunglasses. Intensive and excessive exposure to the invisible ultraviolet rays can lead to painful inflammation in the conjunctiva and the cornea, which could eventually progress and lead to chronic damages. Consequently, you should make absolutely certain that you choose a pair of sunglasses with lenses that bear the CE logo, which guarantees that your glasses meet the fundamental safety requirements of the European guidelines.
Precision sunglass lenses are of course also available with corrective properties. You can also choose from a variety of tints, polarisations and anti-reflective features. When you buy a pair of sunglasses, it is important to discuss your personal needs and the expectations you have of your glasses with your optometrist in detail.
For instance, if you need your new pair of sunglasses also for driving, it may prove helpful to opt for ZEISS lenses with polarisation, i.e. lenses featuring the so-called anti-blinding technology. It minimises the external blinding effects that develop for example when sunlight is reflected by wet roadways. Polarising spectacle lenses reduce such blinding disturbances and improve both, colour and contrast vision. You will enjoy sharper vision and your eyes will not tire as easily. At the same time you can count on dependable solar UV protection, regardless of whether you are spending time on the seaside or in the snow covered mountains in winter.
If you find yourself exposed to frequent changes in light conditions and do not want to have to switch back and forth between different spectacles, consider photochromic lenses by ZEISS with auto-adjusting tints that respond to the different light conditions automatically. They obviously provide solar UV protection as well.
If you need sunglasses for sports activities that will also shield your eyes from the wind or if you are a fan of the unusual, you might want to invest into a pair of curved sunglasses that are great for outdoor sports to simply very fashionable. Once again, make sure you opt for good lenses for your sunglasses. Important: If you are wearing corrective glasses, it is imperative to choose only supreme quality lens designs for curved sunglasses. Lenses that do not meet this standard may deliver blurred vision ranges, especially along the outside edges of these glasses.
For those of you who are in the market for a pair of sunglasses that works well in any application and that accompanies you through all sunny situations in life, the best option is to choose the tint you find the most comfortable from a variety of tints. Besides standard tints, you have the option to select precision sunglass lenses that deliver improved contrast and more saturated colour perception. You will be surprised how precisely your sunglasses can be aligned with your eyes and customised for your needs.
