The Pinnacle of Sunglass DesignIntroducing the Finseekers, the culmination of years of research, samples and development have gone into forming the ultimate colour combinations. Designed to maximise clarity, enhance colours, increase contrast, illuminate dull tones and adapt to changing conditions. Available in both polymer (FS001, FS002, FS003) and glass lens options (FSG003).All variations incorporate an anti-reflective coating on the inner side of the lens. The first of our models to incorporate this feature designed to stop reflection from the users own face.Moving onto the frames, the lightweight yet strong TR90 Nylon will withstand the toughest conditions. The frame design boasts a myriad of features with vents for increased air flow to minimise internal fogging, sweat chambers to wick away moisture, rubber nose pad and tips on the arms provide maximum comfort. To top this all off, the sprung loaded hinges allow for over extension of the arms to not only protect against excessive stress but to also cater for all head shapes and sizes.The Finseekers come with a microfibre cleaning cloth, durable hard case and dedicated quick release lanyard that can be permanently fixed to the frames.FSG003 – Amber AMPM Silver XBlok SWITCH™Our first glass lens into the Fortis range. Relentless development and no expense spared has formed the pinnacle of lens technology. Glass offers a multitude of advantages including clarity, scratch resistance and polarisation.These Italian glass lenses incorporate our SWITCH™ technology. Our Switch or photochromic technology means that the lenses ‘switch’ in colour / shade when exposed to UV light. In bright light the lenses darken, in low light the lenses lighten. This allows the user perfect vision through the course of a session, whether that be at low light at dawn, stalking in the midday sun or looking for subtle signs of fish at dusk. Weight: 41.7g VLT = 13-27%What is VLT?VLT stands for Visible Light Transmission and measures the amount of light that reaches your eyes through your lenses. This is measured as a percentage which indicates the darkness of a lens. The lower the VLT the darker the lens will be. VLT is affected by the colour and thickness of your lenses, the material they’re made of and the coatings they have on them. We have provided a rating on our models to help you choose more wisely.Glass vs Polymer?Choosing the right lens can be confusing, so to make life easier here are the pro’s and con’s of each material. Glass has many pro’s including; 100% polarisation, unrivalled optical clarity, richer tones & better scratch resistance. The benefits of Polymer include being lighter in weight making them more comfortable for long use. They are also more cost effective to manufacture making them a more affordable option without significant compromise to performance.
