I have note that lens color of fake ray bans affects not only fashion sense, but also the ability to detect contrast and distinguish colors. Lenses in some colors can enhance contrast and are very useful. However, this usually comes at the expense of color discrimination and sometimes leads to other problems, such as when you need to clearly distinguish the colors of traffic lights when driving. Some sunglasses even come with interchangeable lenses, allowing you to easily change the lens color when doing different things.
Gray lenses reduce light intensity without affecting contrast or distorting colors.
Brown lenses enhance contrast by filtering some of the blue light, making them ideal for snow sports and most hunting activities when the light is bright and the background is clear.
Amber or yellow lenses can filter out most or all of the blue light, significantly enhancing the contrast, which makes them popular with hunters because the contrast is beneficial for tracking targets in the air. However, such lenses are not suitable for activities that require color recognition such as driving, and are suitable for snow sports.
Red or orange lenses can be used for snow sports, but only on cloudy days. For hunters, orange lenses help spot khaki targets against open backgrounds.
Purple lenses are for hunters who need to spot khaki targets against a green background.
Copper-tinted sunglasses can soften the sky and grass to make the golf ball stand out more.
Blue and green sunglasses will enhance the color contrast of the yellow tennis ball.
Check for color distortion. Check the lenses against fluorescent light. Check the waveform for distortion while moving the cheap Ray ban sunglasses up and down. The absence of distortion means the sunglasses are of good quality.
