Vision Aslak Polarised & Photochromic Fishing Sunglasses UV400 Fly Fishing

Vision Aslak sunglasses are a versatile eyewear range from the Vision collection, designed for anglers who need reliable eye protection and clear vision in changing light conditions on the water. The range brings together three distinct lens technologies — Photoflite, Mirrorflite and Polarflite — so you can choose the model that best matches your fishing environment and personal preference.

Photoflite Series — Photoflite photochromic lenses are the most universal option and suit practically any conditions. The lenses darken in bright light and lighten in low light, allowing you to maintain good vision throughout the day without changing eyewear. This makes them a practical choice for long sessions where light levels shift from dawn to dusk.

Mirrorflite Series — Mirrorflite models are polarised and feature an additional mirrored coating that provides extra protection against bright, direct light and glare. All Mirrorflite models are supplied with a hard case for safe storage and transport.

Polarflite Series — The Polarflite collection offers a range of frame options with ACTIF triacetate cellulose lenses. These lenses provide 100% protection against UVA, UVB and UVC light. They block both direct light and light reflected from the water surface, reducing the flattened, partially polarised glare that anglers often experience. The outer lens surface is resistant to mechanical damage, so the lenses are less prone to scratching during regular use.

All Vision Aslak sunglasses are manufactured in France. The amount of light transmitted through the lens depends on the lens colour, and choosing the right tint helps you optimise vision for the conditions you fish in. On sunny days, lower light transmission is preferable, while in overcast conditions a higher transmission helps you see more clearly.

Brown Lenses — A universal choice with a darkening effect. Brown lenses distort colours the least, so you see a natural image. They perform best from medium light levels through to genuinely bright conditions.

Amber Lenses — Designed for situations with less light. They brighten the view slightly, making overcast days, early mornings and evenings more comfortable than brown lenses.

Yellow Lenses — These act as light amplifiers. They are an excellent choice for very early mornings, late evenings and dark days. On sunny days, yellow lenses are not recommended, as overly bright light can tire the eyes and may lead to headaches.
