Sonnenbrillen werden nach Zweck klassifiziert
Sonnenbrillen lassen sich im Allgemeinen in drei Kategorien einteilen: Sonnenschutzspiegel, helle Sonnenbrillen und Spezialsonnenbrillen.
Der sogenannte Sonnenschutzspiegel dient, wie der Name schon sagt, der Beschattung. Menschen passen den Lichtstrom normalerweise an, indem sie die Größe ihrer Pupillen in der Sonne anpassen. Wenn die Lichtintensität die Anpassungsfähigkeit des menschlichen Auges übersteigt, wird das menschliche Auge geschädigt. Daher verwenden viele Menschen an Orten im Freien, insbesondere im Sommer, Sonnenschutzbrillen, um die Sonne zu blockieren, um Ermüdung durch Augenverstellung oder Schäden durch starke Lichtstimulation zu reduzieren.
Light-colored sunglasses are not as effective as sun-shielding mirrors, but they are rich in colors, suitable for use with various clothing, and have a strong decorative effect. Light-colored sunglasses are favored by young people because of their rich colors and diverse styles, and fashionable women love them even more. Special-purpose sunglasses have a strong function of blocking sunlight. They are often used in the field with strong sunlight such as beaches, skiing, mountain climbing, golf, etc., and their anti-ultraviolet performance and other indicators have higher requirements.
Different groups of people choose sunglasses according to different preferences and different uses, but the most fundamental thing is to start from the basic principles that can ensure the safety of the wearer and the vision is not damaged. Reducing strong light irritation, clear vision without distortion, anti-ultraviolet, color recognition without distortion, and accurate identification of traffic signals should be the basic functions of sunglasses. If the above-mentioned functions are defective, the effect of sunglasses will be lost, and the symptoms of dizziness and swelling of the eyes will be consciously unsuitable. Sometimes, there will be slow reactions, illusions of color discrimination, unequal vision of walking, and traffic accidents. . Therefore, when choosing sunglasses, you can't just focus on style and ignore its inherent quality.
