UV400 protection blocks 99% to 100% of harmful ultraviolet rays, including both UVA and UVB radiation, with wavelengths up to 400 nanometers. Prolonged exposure to UV rays can cause long-term eye damage, including cataracts, photokeratitis, and macular degeneration. Choosing sunglasses with full UV400 protection ensures maximum safety for your eyes.

All of our lenses are polarized as standard. Polarized lenses feature a special filter designed to eliminate intense reflected glare from horizontal surfaces like water, snow, roads, and glass. They improve contrast and visual clarity, making them ideal for outdoor activities.

Unfortunately we do not offer prescription options at this time. As all of our lenses are custom moulded to ensure the best sun blockage, we are also not able to provide polarized lenses that could be swapped with the current lenses either. If this is a feature you would like to request in future models, please let us know at contact@flowstateout.com.
