OUR SUNGLASS LENS MATERIALS
In the competitive and oversaturated sun eyewear market, we offer superior eyewear that is designed to protect you from harmful UVA, UVB and other high-intensity light. Our lens materials help alleviate eye fatigue, improve visual sharpness and enhance depth perception in sunlight.
Within our product range you will find premium, quality sunglasses, suitable for almost any pursuit, with first-class polarized lenses. All this, with exceptional affordability.
We use CR39 lenses made of hard cast resin. CR39 stands for Columbia Resin batch 39, originally manufactured by the Pittsburgh Plate Glass company, then by the Columbia Resins Project in 1940.
Since then, CR39 lenses have become the optical benchmark for lightweight, abrasion resistant lenses, with superior optical clarity and durability. Our CR39 lenses endure scratches, are shatter-resistant and provide outstanding colour consistency.
All our CR39 lenses incorporate an exceptional polarizing filter. Our polarized lenses are created by a refined casting process that results in two rigid, optically flawless and discreet CR39 layers.
Some of the benefits of our CR39 lenses are:
- Best possible filtering effects against unwanted glare from stray light and reflective surfaces.
- Colour saturation enhancement and contrast augmentation.
- Superior and safe optical lens qualities.
- Comfortable and fatigue-free vision.
Therefore, our CR39 polarized lenses help you reduce eye strain, improve visual acuity, provide greater visual comfort, whilst maintaining superior optical clarity. This ensures remarkable durability all in a lightweight yet tough, abrasion and scratch resistant sun lens. Filtering out the reflected light and glare from cars, water, pavement, sand, snow and much more, the filter, enables the lenses to function superbly in the course of any activity where high glare conditions exist. In addition, our CR39 polarized lenses provide a 100% protection against damaging UV-A, UV-B rays, i.e. below a wavelength of 400nm (UV 400)!
It is relevant to note, that UV-C rays do not normally progress beyond the ozone layer of the earth’ atmosphere.
Polycarbonate materials contribute to an even more impact resistant material. Polycarbonate is remarkably strong and can be found on aircraft and motorcycle windshields and sport safety glasses.
It one of the smartest choices of lens material for people who engage in outdoor activities, especially for those who enjoy fast-action sports.
- It is one of the most shatter-resistant lenses available.
- Preferred for oversized lenses to wrap around the face.
- Polycarbonate is naturally a soft material, so it must be coated for scratch resistance. That is why all of our polycarbonate lenses are coated.
We use premium polycarbonate lenses on all of our metal-framed sunglasses, as well as in our semi-rimless and wrap styles. Due to the nature of these types of frames, the use of polycarbonate lenses reduces the possibility of damage.
Our Polycarbonate lenses are characterised by:
- Excellent impact-resistance; more impact- resistant than other types of lenses.
- About 20 to 25 percent thinner than plastic or glass lenses.
- About 20 percent lighter than plastic lenses.
- 100 percent UV rays block, without needing a special coating.
Frequently asked questions
What is polarized glare?
Polarized glare is caused by light waves vibrating horizontally. It can result in eye fatigue, headaches or may even lead to temporary blindness, which can in turn lead to collisions or sustaining injuries when driving.
How long does it take for an average person to adjust to glare?
It can take between 3-6 seconds to adjust to glare. This means that, if glare impairs your vision for just three seconds while driving at 60 kph (37 mph), you may well travel ‘blind’ for 50 metres! This “adjustment time” progressively worsens as you age.
Yes. In addition to the facts mentioned above, those dazzling reflections of sun on the car ahead can be very distracting. They tend to be horizontally polarized, thus perfect for vertically polarized sunglasses. And, What about the brightness of the road itself? Yes. That light is also partially polarised. And, if the road is wet, glare will become much worse.
Why we love Polarized Sunglasses?
Put simply, because they cut out glare. As well, our lenses eliminate 100% of UVA and UVB rays, which results in less squinting and discomfort for the wearer. Moreover, they provide greater clarity and truer colour perception.
How much brighter is reflected and other stray ‘polarized’ light than ‘regular’ light?
It is up to 300% brighter. On a bright day, glare light can be 3-4 times higher than the ambient light you see. This forces you to adjust to the brightness.
Our eyes normally see the best contrast in uniform low-level light. Our polarized sunglasses reduce eyestrain by eliminating the glare that makes your eyes work harder.
Colours are applied to our sunglass lenses to help absorb light as it passes through them. The colour that you choose, is often a matter of personal taste, but there are a few important colour-related benefits to consider.
Our polarized lenses come in a variety of tints. Each colour works better in different light conditions and for certain activities.
It should be noted that solely the colour of the tint bears no relationship to the level of the lens’ UV resistance.
It is considered the all-purpose lens colour because it enables the wearer to see “natural” colours and is very soothing on the eye. It is the best lens colour for bright light situations too. Think of it as a lens that simply “dims the lights”. Plus, grey lenses don’t mess with the wearer’s perception of depth.
Brown is also a great all-purpose lens. They are attractive, warm, inviting and really assist to enhance skin tones. When looking through brown lenses, colours like reds, yellows, and greens are accentuated, but not exaggerated. They can also reduce the glare created by blue frequency light.
Good in varying light conditions. Helps to reduce glare and filters out some of the blue light. Sharpens visual contrast, defines and enhances depth perception.
Coloured lenses might be an appropriate choice if you participate in water sports or other outdoor activities. They can provide good contrast for objects viewed against blue or green backgrounds.
