It will be our pleasure to help you choose from over 800 pairs of sunglasses. We know the latest trend and how it can make you glow. Fashion sunglasses must also sit light and comfortably on your nose, and so we adjust them to you of course. Skiers, pilots, watersport enthusiasts and those who appreciate quality may like to consider polarized lenses, as these minimise reflections from snow, water and when driving and offer you added safety through optimised vision. A 100% UV protection is guaranteed with all sunglasses in our range. The UV test equipment we have on site gives you this guarantee.

Protect your eyes!

The sun radiates an enormous spectrum of high energy. Fortunately, the earth's atmosphere absorbs most of this radiation and therefore allows only a small amount through. That said, the large amount of radiation that makes it to earth means that our eyes, including their adnexa such as the eyelids, need additional protection. In addition to the radiation that comes through the atmosphere, the environment's ability to reflect it back must also be considered.

  Visible light:  UVA  UVB
 Asphalt  7%    
 Grass & deciduous woodland  15%  2%  2%
 Water angle 40°-50°   10%    
 Water angle approx.20°  25%     
 Sand  25%  13%  9%
 Snow  80%  94%  88%
Clouds depending on type  40% - 90%    

Eyes have different degrees of transparency for various types of radiation. If tissue is non-permeable to a particular wavelength, most of it will be absorbed and can be biologically harmful.

Radiation damage occurs in the: conjunctiva, cornea, retina and eyelids. UV irradiation also triggers the development of a grey star (cataract), thereby causing the early onset of presbyopia.

(more details on the individual topics at the end of this article below at 1*))

How to prevent eye damage:

This kind of damage should not be taken lightly. Wearing sunglasses sets a biological control loop in motion. Placing in front a lens that can absorb 80% of visible light makes the constricted pupils dilate again. This control loop, however, detects only the brightness on the retina and not the UV radiation. With a pupil surface now dilated by some 70%, the same dose has a much stronger effect than before. Just one reason why we sell sunglasses. These are the questions we ask:

• where and for how long will the sunglasses be worn?
• for which activity?
• how much work and leisure time is spent outdoors?
• is there any family history of cataracts or macular degenerations?

A brief look at our customer's conjunctiva, iris and skin type gives us the information we need for a consultation.

When a cataract (grey star) or slight corneal opacities start to form, the person perceives more glare. Even in this case, can we solve the problem with a special tint.
In people who are very short-sighted, the ocular fundus reflects brighter light, making the eye more sensitive to glare. Here, sunglasses should have slightly darker lenses.
When travelling in UV-intense regions, it is of course advisable to wear a protective headgear, as well as the indispensable wrap-around sunglasses.

Protection through contact lenses:

UV-absorbing contact lenses can also offer effective protection. Especially soft contact lenses shields the incident rays from the outermost periphery before they reach the cornea, eye lens and retina. The drawback is that eyelids and conjunctiva remain unprotected. Due to the risk of injury (possible physical contact with opponents or when windsurfing, for instance), sunglasses are better not worn for certain outdoor sports. In these situations, it would be nonetheless be advisable to wear contact lenses with low UVB and UVA permeability to prevent consequential damage. This goes for all those pursuing sports, including those who do not require correction lenses.

The fact that excessive glare always leads to loss of visual function and an accident risk is undisputed. Too much UV, especially UVB and blue radiation, significantly increases the risk of developing eye disease. Information-critical colours and semitones, which are required to pursue leisure activities or an occupation, should not be suppressed by protective lenses or contact lenses. Instead, they should be maintained or emphasised slightly if possible.

Damage to the cornea

 

Cornea damage is a consequence of photokeratitis, commonly known as snow blindness, or in a lesser form as light conjunctivitis. The unprotected eye reacts first and foremost to UV radiation. Radiation is increased by up to 20% for every 1000 vertical meters. The foremost layer of the cornea becomes damaged. Extreme pain occurs only after about five to ten hours and subsides one to two days after treatment.

UV irradiation influences the development of a cataract

 

Today, UV radiation can and must be held responsible for the formation of a grey star (cataract). Of course, certain hereditary factors and influences such as diabetes, an unhealthy diet, medication, nicotine and trauma can also encourage the star formation.


1c*)

Radiation-induced damage to the retina

 

The optical refraction of the eye concentrates the incident radiation on the retina. The radiation values are around 150 times greater than those on the bare skin. We understand the devastating consequences of watching a solar eclipse without proper sunglasses. If eyes are inadequately protection, a solar bull's eye occurs and this leads to slight to complete loss of central vision. Treatment is difficult, required immediately and sometimes unsuccessful. Galileo Galilei clearly suffered from this disease after observing the sun with his telescope. Because solar eclipses and media enlightenment are rare, this extreme case occurs infrequently yet still far too often. Yet damage also occurs when the radiation lies only slightly above the biological defence mechanisms. The weighting of photochemical damage with respect to the visible spectrum is what is referred to as blue light damage to the retina. In a predisposed person, this is thought to be partially responsible for macular degeneration. Unlike adults, children do not have the mechanism for UVA and UVB radiation to absorbed by the media in front of the retina. The risk for children, then, is much higher!

Palpebral fissure

 

Especially in older people, the conjunctiva can develop a palpebral fissure, also known as pinguecula. This small, usually yellow-coloured elevation often occurs in the nasal area, rarely in the temporal palpebral fissure area (at 9 o'clock or 3 o'clock) shows no sign of spreading across the cornea. The tissue of this small conjunctiva area has changed and is easily visible. It contains protein, fat and calcium. It can become irritated. These palpebral fissure are rarely perceived as bothersome. But they can make it difficult to adjust contact lenses. All fissures in the conjunctiva must be distinguished from benign or malignant tumours, or those that are at risk of degeneration. It is always advisable to seek medical attention.

Premature presbyopia and other assumed damage

 

A negative impact of UV radiation on focusing close up occurs among the younger age groups more often in countries with a high UV value. Presbyopia occurs earlier. The study situation is still too uncertain to make a conclusive statement.
The fact that UV radiation encourages the inflammation of choroid, ciliary body and iris, however, is substantiated.


1f*)

Pterygium

 

A benign, vascular growth that can be seen on the conjunctiva with the naked eye is the pterygium. The conjunctiva doubles from the nasal canthus outwards and has the shape of an elongated triangle, the tip of which has grown together with the cornea. It rarely grows up to the central cornea. People who spent their early childhood at latitudes of less than 30° tend to have a higher risk of developing this disease. People who live in rural areas develop a pterygium around five times more often than city dwellers. High temperatures and a dry environment likewise encourage formation and progression. Artificial tears and wrap-around UV-blocking glasses, as well as wearing a sun hat, are the primary treatment.

Eyelids

 

Radiation, mainly in the UV-range, can cause tumours and benign basal cell carcinomas, but also malignant melanomas, on the eyelids. Although hereditary factors do play a role, the key trigger is UV radiation. Increased UV exposure during childhood and adolescence is considered to be the cause of malignant melanomas.
