You love golf, and while the prospect of playing a full day's worth with your painfully clumsy father-in-law sounds feels sort of like pulling teeth, you just have to do it. Thankfully you can shield your grimacing eyes with the Tifosi Optics Tyrant 2. 0 Photochromic Polarized Sunglasses. Crafted to transition easily between light and dark, the Tyrant 2. 0 easily waffles between the shade and bright terrain with ease. You know, just in case you have to go fishing for golf balls for the millionth time. The frames are constructed with a durable, homopolyamide nylon called Grilamid TR-90 that's known for its low density, high resistance to chemical and UV damage, and incredible bending strength. The Tifosi polycarbonate lenses protect you against harmful UVA/UVB rays with its true polarization that's embedded into the material itself rather than simply coated with a thin layer of polarization treatment. Not to mention, these decentered lenses are also furnished with ventilation and a glare guard, which prevents unnecessary glare and increases airflow, in turn preventing fogging and encouraging optimal visibility.
