| Abstract | |
There is a strong association between high energy blue light exposure and development of some ocular diseases such as age-related macular degenera-tion. In recent years there has been increased people's concern about the damage caused by blue light and ways to prevent them. This study aims to develop and build a device for measuring protection against harmful blue light to human eyes in sunglasses and to determine whether this protection is adequate, adopting as criterion its blue light transmittance be less than 1.2 times its luminous transmittance. To obtain the proper spectral weighting functions, the measurement will consist of linear combinations of the responses of a TCS3472 photosensor illuminated by a high brightness white LED. The agreement between the measurements made with the proposed device and a gold standard will be analyzed by the Bland-Altman method. Sunglasses blue light protection values will be measured to analyze whether sunglasses in brazilian market are protected against harmful blue light. The developed device will be available to public to measure their own sunglasses. (AU) | |
