Get the eye protection and style you want without spending a fortune with the Intense Sunglasses from Tifosi Optics. Starting with the frame, it uses an incredibly light and durable nylon material known as Grilamid TR-90, that resists chemical and UV damage. Moving to the lenses, they feature vent cutouts for increased airflow helping to prevent fogging and keep you cooler. You'll get 100% protection from harmful UVA and UVB rays and enjoy glare guard, a lens coating that reduces eye strain. Also, the lenses are optically decentered, a feature that is common on higher priced glasses that eliminates distortion and prevents unwanted magnification. Various tint lenses, sold separately, are easily interchangeable for the different light conditions. A final note on the lenses is they are made of polycarbonate, ensuring that they are scratch-resistant and shatterproof. The glasses sit comfortably on your head thanks to the adjustable nose and ear pieces that allow for a custom, comfortable fit that, along with the hydrophilic rubber that increases its grip the more you sweat, limit slippage.
