Abstrakt

The function of the human eye is to receive electromagnetic waves and transform them into electrochemical signals, which interpreted by the brain create the sense of sight. However, its capacity for withstanding radiation, especially the ultraviolet part of the spectrum, is limited and exposure that exceeds these limits can cause serious ocular damage. Sunglasses are so far irreplaceable when it comes to the photoprotection of the eye. According to popular opinion, the brands and high prices of the sunglasses are satisfactory evidence of adequate performance. The purpose of this study is to determine whether these criteria offer a correct evaluation of the sunglasses’ protective abilities and to emphasize on the importance of complying with the current sunglass standards (AS/NZS 1067:2003, EN 1836:2005, ANSI Z80.3-2008).
