Can an unaided human eye tell if light is polarized?

An unaided human eye cannot directly detect light polarization. However, certain phenomena, such as the visibility of glare from surfaces like water or roads, can indicate polarization. By using polarized sunglasses, individuals can observe changes in brightness and glare, which can help them infer the presence of polarized light. Ultimately, while the eye itself cannot determine polarization, it can perceive effects related to it.
