Blue-light transmittance in sunglasses plays an important role for the consumer regarding eye health. Current standards do not have specific requirements for blue-light protection, as in the past. However, the literature has warned about the potential harms of blue light for the eye. The limits imposed in the past state that the average transmission in the 380 nm to 500 nm region should not exceed 1.2X the transmittance in the visible range (380 nm – 780 nm). This work investigates, besides the transmittance of blue light in sunglasses, whether those limits imposed aiming to eye health are respected. Additionally, this study examines the blue-light transmittances pre- and post-artificially aging the material in a solar simulator. Twelve samples of sunglasses were tested for compliance with a former standard and submitted to the aging process up to 2500 h within the solar simulator. The results showed relevant changes in the lenses over time, that is, they considerably lost their blue-light attenuation capabilities. The results suggest that the aging test should be carried out on sunglasses not only for ultraviolet radiation, as required by most standards, but also for blue light. Furthermore, the standards should comprise some constraints concerning the blue-light attenuation.
