What are the colors of the fishing polarizer?
Amber, yellow, or orange lenses are very suitable for wearing on cloudy days. They can have a very clear vision, but they are not suitable for use on sunny days. Gray or dark green lenses can maintain the most natural original color when viewing objects, which is a good choice. Sunglasses are not only required to be worn in summer but they must also be used throughout the year. Wear it on sunny days and also on cloudy days. Don't think that the sun is not strong on cloudy days and the weather is not hot, so you don't need to wear sunglasses. The harmful ultraviolet rays will harm your eyes unknowingly. Therefore, even if it is a cloudy day with thin clouds, you must still wear sunglasses to protect your eyes.

Koala Eye sports sunglasses have high-cost performance and fashionable design. The lens also contains absorption of infrared and ultraviolet technology, which can fully protect athletes' eyes. As for the polarized sunglasses, in addition to basic UV protection, they also can prevent glare, prevent pavement reflection light, surface phosphorescence, and so on, very suitable for fishing. When the light is strong or there is a reflective light source on the surface of an object, it does act as a good light filter, protecting the eye from the sun's exposure and the reflection of light from the water.
How to test a blue-light lens?
Blue light-blocking glasses have many membrane layers, and all kinds of colors of the film are not the same. Actually, the membrane layer of anti-radiation effects is not large but has high strength and chemical resistance of lining norm of glasses and the effect of protection for the eyes is very important.
How to Keep Glasses from Slipping
Stick-on Nose Pads
Nose pads would be a good choice to prevent glasses to slide down your nose. Hence, you can stick a pair of rubber pieces in the nose pads of your glasses or you can choose a pair of glasses with rubberized nose pads. If you want to try a pair of nose pads glasses, the Koalaeye Optical may be a good choice. The rubber nose pads will make you feel steadier and better and the additional resistance on the nose pad will surely provide more support. So, if your glasses often slip down from your nose, try this way.
Wax Coating
To keep glasses from slipping, you can try wax coating which is a smart move. Use the wax on your nose pad area along with the temple where the glasses come into contact with the skin. In general, it works fine and it is nearly invisible.
Temple Ear Hook
The temple ear hook is a good way to keep glasses from slipping. It can provide mechanical support behind the ear and you will feel the support from the back of your ears. But the drawback of the temple ear hook is that it is quite visible. When you take off the lenses, you need to lift the temple higher so that the ear hook could clear the ear’s crest. Besides, the cheaper one might cause some discomfort to the back of your ears because of the pressure.
Rubber Bands and Hair Ties
To keep glasses from slipping, you can also try hair ties and rubber bands. You can tie one around the temple tip behind your ear so that it can provide both slight mechanical support and friction forbidding your glasses from moving around. What’s more, this is a low-cost method.
Competition in visual marketing
The offline experience of consumers is pretty important. Store space design, planning and layout, and commodity display form are important parts of visual marketing. If all three can be balanced and matched, it will drive sales growth.
Parameters of lens material selection
Abbe number
Since the refractive index of the lens material varies for the light of different wavelengths, and white light is made up of various colors of light of different wavelengths, the dispersion phenomenon occurs when the lens refracts white light. The dispersion coefficient is an important index to identify the sharpness of lens imaging, which is usually indicated by Abbe number (Abbe number = dispersion coefficient). The larger the Abbe number, the smaller the dispersion, and vice versa, the smaller the Abbe number, the larger the dispersion, and the worse the resolution of the image.
Impact resistance
Humans have been using glass lenses for about 300 years, and it was not until 1947 that the first resin lenses made of CR39 were produced. A big reason for using resin lenses is their safety, i.e. impact resistance. Only lenses that pass the Drop Ball Test are considered safe. Combining the above two parameters, we can compare different lenses.
