Summer has arrived, and when we prepare sunscreen, in addition to sunscreen, sunscreen clothes, and sunscreen umbrellas, there is also an essential item that is sunglasses.

The main function of wearing sunglasses is to resist ultraviolet rays and protect the eyes. In addition, as a fashionable item, it can also add color to simple clothing. When you are too lazy to dress up in the summer, even a simple white T-shirt paired with sunglasses can immediately boost your spirits.

Sunglasses have two simplest and most commonly used functions: shading and beauty. When choosing sunglasses, we mainly look at UV index, color, shape, material, and weight.

The UV index, in simple terms, refers to the effect of filtering ultraviolet rays and cannot be replaced by ordinary glasses. Eyes are the window to the soul. For glasses, especially functional glasses, to ensure accurate lens data, everyone should look for the best place to buy eyeglasses to purchase.

In addition to the material of the lenses, the material of the frame is also important. At present, most of the mirror frame materials on the eyeglass mart are CP material, polycarbonate, epoxy resin, aluminum magnesium alloy, and titanium material.

The most commonly used ones are resin and alloy frames. Resin is lightweight and has a memory function (can be snapped back), while alloy frames are stronger and less prone to deformation. However, the styles of the frames are relatively regular, and many of them do not look as good as resin frames.

Material and weight are often forgotten when choosing a style, but no matter what material you choose, remember to choose the most comfortable and lightweight frame you feel when wearing.
