Purpose: The study surveyed current customers sports sunglasses purchasing and wearing habits in order to evaluate the current situation and study the optical performance to the ocular side effects of wearing sports sunglasses.
Methods: The study surveyed 147 customers who had been using sports sunglasses. We investigated the customers’ motivations for wearing sunglasses, their vision correction method, purchasing store, brand selection, the awareness of warnings about the use of sports sunglasses, and the ocular side effects. Optical performance was obtained by the lens power, lens parallelism, astigmatism by selecting a 10 products.
Results: 73.5% of the customers wore sports sunglasses for glare reduction, which was the top motivation. 10.2% of them wore them for eye protection, 9.5% for visibility, 2.7% for the aesthetic effect, and 4.1% for other purposes. 43.5% usually purchased their sports sunglasses from online stores, while 25.3% bought them from optical stores, 12.2% from specialized shops for goggles, 10.2% from duty-free shops, and 4.1% from others. 44.5% of the customers who wore sports sunglasses had experienced side effects, while 55.5% had not experienced any side effects. The refractive power of the lens sport sunglasses 0.01 D~0.37 D, prismatic power is 0.01 △~0.26 △, longitudinal astigmatism, -0.0098 D~0.1080 D, transverse astigmatism is -0.0084 D~0.1872 D.
Conclusions: The person feels the visual side effects when wearing sports sunglasses and could feel the visual side-effects through the optical analysis requires a prescription and fitting of opticians.
