Lens materials

We like to keep things simple and for lenses we only use two different materials.

For almost all our sports styles including shooting and cycling models we use polycarbonate. This is the ideal lens material for sports eyewear. It has up to 10 times more impact resistance than regular plastic lenses. We use a minimum thickness of 2mm which means the lenses will withstand the impact test requirement of EN166F. Historically the image transferred to your eyes with polycarbonate was poorer quality than plastic but with the advent of Class 1 Optical Grade polycarbonate the difference is now much less significant. All our polycarbonate lenses are Class 1 optical quality. Additionally, polycarbonate naturally blocks most UV light and do not need the application of a UV coating although we always apply a UV filter coating to all our lenses to ensure our eyewear can be UV400 rated.

The other lens material we use is TAC (Triacetate) for our polarised models. In common with Evolution it’s used on virtually all lower priced polarised sunglasses. This multi-layer material has the polarised film applied to the front of the lens. Even though it’s multi-layer, a TAC lens is thin, usually no more than 1.2mm providing little impact protection and they can shatter, so Evolution polarised sunglasses should not be used if impact protection is important.

Frame materials

Historically, we used polycarbonate to make our frames (a different grade of polycarbonate to that used for lenses). About 2 years ago we switched over to TR90 and all current production now uses TR90. TR90 Grilamid is a type of nylon and the one of best materials available to make eyewear frames. It’s super strong, flexible and lightweight for all-day wear. It’s more resistant to extreme temperatures and has high chemical resistance. As the material is pliable, TR90 frames are far less likely to break or bend from impact. TR90 is more expensive to use and so not not normally found on less expensive eyewear. Another good reason to buy Evolution!

Our high quality Evolution cap, made by cap specialists Beechfield, is black with a grey trim and features an embroidered Evolution colour logo. Made with 100% cotton in a contrast panel design with red piping. It has stitched ventilation eyelets, a pre-curved peak and is universal sizing/fitting with a quick Rip-Strip™ size adjuster. The normal price is £6.95 but it’s yours FREE when you spend at least £20 on anything on the website – just use voucher code ECAP to claim at checkout. Offer ends 31.10.21.

Following the UK’s departure from the European Union, the UKCA (UK Conformity Assessed) marking is the new UK product marking used for goods being placed on the market in Great Britain (England, Wales and Scotland). It covers most goods which previously required the CE marking. The requirement for UKCA marking came into effect on 1 January 2021 but to allow businesses time to adjust to the new requirements, products made after this date can still use CE marking alone until 1 January 2023.

UKCA marking applies to most goods previously subject to the CE marking. The technical requirements products must meet are largely the same as they were for the CE marking.

The vast majority of manufacturers (including ourselves) will use self-declaration for conformity to UKCA just as we have for CE marking: providing of course that the product has been made to the relevant standard (in the case of sunglasses and most eyewear that’s BS EN ISO 12312-1:2013). The new requirement does not apply to existing stock; if it was manufactured and CE marked before 1 January 2021 it can still be sold in Great Britain with a CE mark, even after the 1 January 2023.

The UKCA marking is not recognised on the EU market. For that reason, unless a product is only going to be sold in GB, you will likely see both CE and UKCA marks applied to products including sunglasses and eyewear. From January this year we started to apply the UKCA mark on all Evolution sunglasses and eyewear and, as we also export to many EU countries, we will also apply CE marking too.

We’re often asked about small fit sunglasses to suit teenagers and the many adults (men & women) with smaller faces. To meet this demand we’ve just added the new Spin model. It features a matte black frame and grey (category 3) lenses with blue flash mirror finish. Spin has classic, timeless styling and Class 1 optical quality lenses. The frame is made from super strong TR90 that’s lightweight for all-day wear. The polycarbonate lenses are impact resistant, shatterproof and UV400 Rated. Supplied with a soft carry pouch it’s just £14.95. View Spin (Small Fit).

 

We have some fantastic offers in our Clearance section: most are under half their original price. Every one is brand new and has never been on display anywhere (not ‘returned stock’) so exceptional value. They are in Clearance because they’re older models and it’s the last of our stock. However, as with all Evolution models they all have high quality frames and distortion-free lenses that are UV400 rated. Each one is supplied with a soft carry pouch and our two year “no quibble” guarantee still applies. Prices start at just £3.95! Check them out here.

Lots of reports in the UK media about people, including children, getting sunburned – underestimating the power of summer and especially midday sun, when the risk of risk of sun burn is ever present. It really is essential to have sunscreen on and wear sunglasses when you’re out and about.

One in five people will get skin cancer in their life time and that includes cancer of the eyelids. It is estimated that 90% of the new cases of skin cancer each year are preventable if people just took sensible safety measures. According to the charity Cancer Research UK, apart from the immediate pain, a sun burn can double your risk of skin cancer. Those with lighter skins and children are more at risk.

So, here are our top tips to avoid highly damaging UVR:

– Wear sunscreen even on cloudy days. Sunscreen protects the skin from burning – select a sunscreen with an SPF (sun protection factor) of at least 30 and 50 for children and those with lighter skins.

– Always use UV400 rated sunglasses, not just to protect you from damage to your eyes; the eyelid skin is very thin and this puts it at high risk of UV damage. All Evolution sunglasses & eyewear are UV400 rated.

 

 

Due to the pandemic we last did an exhibition in September 2019. This year only one of the usual events we do is taking place but as it happens it’s the biggest and best! We’re delighted that the 2021 Game Fair is going ahead. If you’ve not been to one before it’s a fantastic celebration of the countryside and a ‘must attend’ event for everyone that loves fields sports. It’s taking place at the wonderful Ragley Hall near Alcester, B49 5NJ (and close to Stratford Upon Avon) over the weekend of Friday 23 – Sunday 25 July (3 days). 120,000 visitors are expected and around 850 exhibitors will be there; including us! Look for the stand of our sister company, Sunglasses For Sport (stand no. K728) near to The Gunmakers’ Pub.

We 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.

We’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.

Target 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 £34.95 with free UK delivery.

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:

• 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.
