There are many kinds of helmet lenses, mainly including colored lenses, painted lenses, polarized lenses, anti reflective protective lenses and color changing lenses.

The types of helmet lenses are detailed as follows:

Anti reflective protective lens This kind of lens is coated with a thin layer of magnesium fluoride on the surface to prevent strong light reflection, so that you can see things more clearly without being disturbed by strong light.

Colored lenses, also known as "dyed lenses", are used to absorb light of specific wavelength by adding some chemicals to make the lenses appear color during the lens manufacturing process. This is the type of lens commonly used for sunglasses.

In order to filter the dazzling light from the sun shining on the water, land or snow in the same direction, the polarized lens is called polarized lens by adding a special coating in the vertical direction to the lens.

Color changing lenses are also called "sensitive lenses". Because silver halide chemicals are added to the lenses to make the originally transparent and colorless lenses become colored when exposed to strong light for protection, it is suitable for indoor and outdoor use at the same time.

Colored lenses present the same effect as colored lenses, except that they are made in a different way. They are painted on the surface of the lens, which is known as "gradually colored lenses". The color is darker on the top, then gradually lighter from the bottom.

The sunscreen color of helmet lens is black. The black helmet lens belongs to the filter lens, which is a cheaper accessory that can obviously change the appearance of photos.

Helmet lens The function of black helmet lens is as follows:

It can prevent dazzling and reduce eye fatigue, improve resolution and play a certain role in heat insulation.

It is recommended to have a good polarization filter, which can be used in both color photography and black and white photography. It is absolutely worth proud to have a high-quality polarization filter. Polarization filter is a filter that absolutely does not exist.

Some foam cushioning materials for helmets have very low density, which is even worse than the foam cushion used for home appliances. It will break with a light hand digging - unqualified.

Some materials of the lining are uncomfortable to touch. Pay attention to the selection.

Be careful that the small black heart factory uses recycled materials to make helmets. The helmets will break if you drop them gently. They will smell and soften when the sun shines, and may contain some toxic and harmful substances in the garbage during recycling. Because this kind of helmet is super cheap, many people buy it. For safety, we must not be greedy.
