Just in! Brand new safety eyewear range

Evolution Safety Eyewear - newWe are delighted to announce the launch of our new safety eyewear range. Manufactured especially for us, there are two models:

  • Evolution Guard safety spectacle
  • Evolution Cover, a dual purpose safety spectacle / over glass (will fit over prescription glasses)

They are available in 3 colours: Grey, Yellow & Clear. Both models comply with BS EN166:2001, ANSI Z87.1, EN170:2002 & EN172:1994. They have been independently tested & certified by SATRA Technology Europe Ltd (European Notified Body number: 2777). All lenses are Class 1 optical quality and UV400 rated. Amongst the many other features is an anti-fog coating to both sides of the lenses. This is ‘high spec’ safety eyewear but at very competitive prices. See them on our Safety Eyewear page.

Another Category 4 sunglass released

Evolution Strike - Category 4 sunglassesWe’ve just introduced this Strike model with category 4 lenses. In total we now have 5 sunglasses with these dark lenses. Category 4 lenses let in less than 8% of light – in the case of the new Strike model it’s 4.4% so the lens blocks just over 95% of visible light reaching the eye.

Category 4 lenses are ideally suited to mountain climbing and high altitude skiing and hiking where intense sun glare can be experienced. They can also be used for desert trekking – again where there is intense sun. Such lenses will also help anyone that suffers from sensitivity to light especially strong sun – a fairly common condition known as photophobia.

One important factor to bear in mind with category 4 lenses is that they should not be used for driving as they are too dark and potentially dangerous for driving. That’s why the frame or lens should be clearly marked that the model is category 4.

New eye dominance correction kit

Evolution Strike EDK Eye Dominance KitTarget sports including clay shooting is undertaken with a dominant eye but this is not always the same as the dominant hand. Quite often a right-handed shooter is left eye dominant (and vice versa). This means that with both eyes open the shooter may see two barrels, two targets or will be looking down the left side of the barrel (the opposite applying for the left handed shooter that is right eye dominant). It’s such a common problem for clay shooting enthusiasts that there are all sorts of correction aids on the market ranging from dots/patches (to stick on eyewear lenses), fibre optic beads, barrel mounted devices and so on. Now we have entered the fray with our brand new Strike EDK (Eye Dominance Kit) that’s specifically designed to help overcome eye dominance problems. It does this by having a Category 4 very dark lens in front of the dominant eye (the “off eye”). This dark lens has a 4.4% VLT (visible light transmittance), which means it only lets in 4.4 % of visible light, blocking 95% of light reaching the eye. The other lens in front of the non-dominant eye can be either clear or yellow (interchangeable lenses). It means the shooter can keep both eyes open and there will still be vision through the dark lens but the non-dominant eye, looking through the clear or yellow lens, should take over.

The Strike frame is made from lightweight but super strong TR90, has adjustable nose pads and non-slip arms. All lenses are made from optical grade polycarbonate with full impact protection and they are all UV400 rated.

The Kit comes with the dark grey Category 4 lens and optional clear and yellow lenses plus a soft carry pouch, cleaning cloth & hard case. A pair of Category 4 dark grey lenses is provided in the kit so that the user has the option of also wearing a pair of dark tinted sunglasses (useful when shooting directly into the sun). Kits are available for both left eye and right eye dominant shooters. Our new Strike EDK is just £29.95 including free UK delivery.

Sunglass lens categories – what do they mean?

Following the last news post about polarised lenses, along a similar theme we thought it worthwhile explaining what the different sunglass lens categories mean. The category number equates to a percentage of the VLT (Visible Light Transmission) that is, how much light the lens lets through. The higher the VLT the lighter the lens, conversely the lower the VLT the darker the tint will be, blocking more light coming through to the eye, as follows:sunglass lens category table

  • Category 0: 80-100% VLT
  • Category 1: 43-80% VLT
  • Category 2: 18-43% VLT
  • Category 3: 8-18% VLT
  • Category 4: 3-8% VLT

The following is a general guide to the categories that apply to different lens colours. This has to be a general guide as the VLT can cover quite a wide a spectrum such as Category 1 which is 43-80%. Some lens colours are right on the “border” e.g. a yellow lens can have 78% VLT which is on the border between Category 0 and Category 1.

  • Category 0 – Clear, Light Yellow, Pale Orange
  • Category 1 – Yellow, Orange, Rose & Vermilion
  • Category 2 – Purple, Red, Amber & Light brown
  • Category 3 – ‘Standard’ Grey & Brown
  • Category 4 – Dark Grey & Dark Brown

Virtually all the grey and brown lens sunglasses we sell are Category 3 and suitable for use in strong sun conditions. See our range of leisure sunglasses.

Category 4 sunglasses are a specialist lens for intense sunlight/high glare conditions and they are clearly denoted in the product description. They also appeal to people that have very light-sensitive eyes (called photophobia). It’s important to note that a category 4 lens must not be used for driving as they are too dark and therefore potentially dangerous. It’s also worth pointing out that tint has nothing to do with blocking UVR. You can buy cheap sunglasses with a category 3 lens but without UV filters it can let in very harmful levels of UVR, damaging the eye. This is why good quality sunglasses have UV coatings applied to the lenses. Some lens materials do naturally block UV such as glass and polycarbonate.

Polarised Sunglasses – why polarised lenses are different

polarised sunglasses - roadOne of the questions we’re often asked is “what makes a polarised lens different?” Light waves from the sun travel in all directions but when they strike a surface like a road or water they begin vibrating in one direction, usually horizontally. This is called polarised light and it’s this harsh concentrated light – glare – that make it difficult to see and uncomfortable for your eyes. Polarised lenses are different to standard sunglass lenses; they have a special filter film either sandwiched between two other layers of the lens or applied to the front of a lens. The polarising filters used in polarised sunglasses absorb the horizontally-vibrating waves that reflect off a surface. That means that only vertically-vibrating waves get through the filter and reach your eye. This greatly reduces the intensity of reflective glare. Non-polarised sunglass lenses only reduce the amount of light entering the eye; they don’t block glare.

Glare not only makes it difficult and uncomfortable to see and can cause eye strain it also distorts the true colour of objects and makes them harder to distinguish. With polarised sunglasses you get glare-free vision, clear contrasts, more natural colours and reduced eye strain or fatigue. Glare also causes a mirror-effect on water. As a polarised lens will eliminate glare on the water it means you will be able to see down below the water surface which is why they are so popular with fishing enthusiasts.

It’s worth noting that whilst there are many benefits to wearing polarised sunglasses, virtually all polarised sunglasses under £50 (including all Evolution models) use a multi-layered lens material called TAC (Triacetate) with the front layer being the polarised film. A TAC lens is quite thin, usually no more than 1.2mm and does not provide impact protection, so for sports like shooting where impact protection is required, a TAC polarised lens is not recommended.

Shop our range of Polarised Sunglasses, with glare blocking lenses making them suitable for fishing, boating, sailing & watersports, skiing and driving.

Now is the time to keep an eye on the UV Index

The UV Index, also known as the Solar UV Index, was developed by the World Health Organisation. The UV index forecast identifies the strength of ultraviolet radiation (UVR) from the sun at a particular place on a particular day, allowing you to take the necessary precautions to help reduce the impact of UVR on your health. As we know, small amounts of UVR exposure can be beneficial as it is essential for the production of vitamin D, however over exposure to UVR can lead to serious health issues such as skin cancers and eye damage that could result in cataracts and macular degeneration later in life.

The strength of UV varies depending on where you are in the world, the time of year and on a number of different weather factors such as the amount of cloud cover.

Here in the UK the UV index does not exceed 8 (8 is rare); 7 may occur on exceptional days, mostly in the month of June. Indices of 9 and 10 are very common in the Mediterranean area.

UV index

UV Index

  • 1-2 Low
  • 3-5 Moderate
  • 6-7 High
  • 8-10 Very high
  • 11 Extreme

The aim of the index is to warn people of increased risk and encourage them to use sun creams, sunglasses and hats when outdoors.

Why eyewear mists up when wearing a mask and how to stop it

If you’re now regularly wearing a mask on your face you’ll have noticed that your sunglasses, spectacles or medical goggles are prone to misting up. This is because the mask directs your breath upwards instead of in front of you, which is good for preventing disease transmission but a nuisance as it interferes with your vision. Sports eyewear that’s close fitting is also prone to mist up and for that reason we have Evolution branded anti-fog products. The one shown is made for us by an Italian company and it’s the most effective anti-fog product we’ve tested (and we’ve tested many!). You’ll find it in our accessories section.

The ‘go to’ brand for shooting eyewear

In the recently released May edition of Sporting Shooter magazine, editor Rebecca Green said, ‘Evolution Eyewear has long been the go-to brand for shooting glasses’. This was the lead comment on an editorial piece on our new Evolution Edge shooting eyewear, described by Rebecca as ‘offering shooters of all disciplines top quality protection with a great variety of lens colours to choose from’.
