The rays of the sun give your mind, body and spirit the sense that you are on vacation and put a smile on your face. UV protection protects not only your skin, but also your eyes, and guarantees that you will enjoy the sun without regrets. Not wearing sunglasses can cause damage to your cornea, lens and conjunctiva. ZEISS sunglass lenses provide reliable UV protection.
Actors, musicians and show business people wear them all the time – summer and winter, day and night: sunglasses. However, they are much more than a cool accessory. In fact, sunglasses protect your eyes from dangerous UV rays. When you buy a pair, though, make sure you choose good quality.
While even the lowest-priced models offer adequate UV protection, the lenses in cheap models are usually pressed and not cut. Consequently, these lenses may not provide good vision. Especially if you wear sunglasses for an extended period of time, this may fatigue your eyes. Cheaper sunglasses are also harder to adjust and even if you wear them only for short periods of time, they may leave impressions on your skin. That is just not cool.
Tip: Before you buy a pair of sunglasses, see your eye care professional and have him give you detailed advice on glasses with good UV protection. Test the difference between quality lenses and basic pressed lenses.
Why you should wear sunglasses: While your eye does adjust itself to different levels of brightness with the assistance of its pupil which contracts when strong light penetrates the eye, it can only do this up to a certain level. If your surroundings are very bright, your eyes may be dazzled – and you may not be able to see at all, regardless of your otherwise normal vision.
A good pair of sunglasses will prevent this from happening. Another very important factor is that it provides excellent UV protection. Intense yet invisible ultraviolet rays or extended exposure to them can eventually lead to painful inflammation of the conjunctiva and the cornea and ultimately cause damage. There are a few warning signals that will tell you that your eyes have been exposed to too much sun: They feel fatigued, red and tense, and sometimes they will tear up. If this happens, make sure you keep them out of the sun for a few days and buy a good pair of sunglasses.
Carl Zeiss Vision also offers a range of sunglasses that have been treated with premium quality immersion dyes. They have been developed for specific applications that call for increased UV and glare protection on the one hand and that meet certain contrast requirements on the other hand. Sports such as paragliding, skiing, motorcycle or bicycle riding frequently occur under extreme light conditions. Contrast-rich vision is of particular importance – especially for safety reasons.
Patients with retina problems need special sunglasses. ZEISS special filter lenses provide ideal solutions. They absorb parts of the visible spectrum completely. Receptors that are sensitive to this range are intentionally underexposed to protect the eye. These glasses are particularly helpful for patients suffering from retinitis pigmentosa, i.e., diabetic retinopathy. Carl Zeiss offers a series of so-called filter clips.
