HINDAR blue light blocking glasses

With advanced equipment, system production, and strict management, they adopt German technology and PARUPU lens geometric structure owned by HINDAR OPTICE LAB, which can effectively block various kinds of blue light, ultraviolet light, and other different wavelengths, to protect the health of eyes. Since its inception, Hindar has enjoyed a lot of popularity, and while it has achieved some good results, it has not slowed down and is still striving to become the top brand in the industry.


Lunor

Lunor glasses integrate classical aesthetics into modern design and are compared to modern antiques. Lunor glasses insist on handmade, and some styles need 200 processes to complete. In addition to the fine processing of the frame, in Lunor, each glasses box made of wood or sheepskin was made by hand in a German factory, making the whole product like a work of art and pretty valuable.



How To Use Contact Lens Correctly?

Check your eyes for abnormal cases. Do your eyes sting or dry? If so, it is recommended not to wear contact lenses for the time being. Look in the mirror to see both eyes carefully, if it is red and swollen or if is both eyes full of bloodshot? If you do, you can no longer wear contact lenses, and you can go to a professional store for inspection. After putting on the contact lenses, block the left and right eyes respectively to see if the vision of one eye is clear. If the eye vision has decreased or blurred, check if the lens is dirty. If the lens is still the same, you should go to a professional store to find out the reason.


What Is Bifocal Lens?

Changes in vision seem to be related to age. Presbyopia, a common eye condition that occurs in middle age, causes changes in your eye’s ability to focus. But this condition can be corrected by wearing bifocal glasses.

Bifocal lenses are divided into two parts to accommodate two different prescriptions in one lens. One area of the lens will have one prescription (usually distance) and a segment in the lower half will have the other (usually near vision).

The bifocal glasses were invented by Benjamin Franklin, who solved his own vision problem by taking the lens from his reading glasses and distance glasses and cutting them in half. Then remade the cut lenses into a single pair of bifocals and put the distance lens on top and the reading lens on the bottom.



Why should children be more vigilant about harmful blue lights?

The amount of light transmitted to the retina through media such as the cornea, lens, and vitreous is age-related. Blue light poses the greatest risk and damage to the eyes during adolescence. As our eyes' refractive media naturally yellows, more blue light is absorbed, preventing it from reaching the retina. The lens transmittance of children under the age of 10 is more than six times higher than that of adults. It is important to prevent the damage of blue light to children's visual health.


Choose the right clear sunglasses for your face shape.

A clear eyeglass frame suits the person of different face shapes according to different shapes. For example, a heart-shaped face suits the clearest eyeglass frame, and a square face suits an elliptical transparent eyeglass frame. A round face suits the clear eyeglass frame with an outline. The long face suits the clear eyeglass frame with some width and so on. There are many kinds of clear frames, like oval, round, square frames, and so on.

When choosing clear frames, be careful to choose one that fits the shape of your face. Oval and the round clear frame are more suitable for heart-shaped faces, square faces, and long faces. People with round faces should avoid large frames, dark frames, and wide edges, and don't wear round or square frames.



What is a progressive lens?

Progressive multifocal lenses are lenses with different upper and lower powers for seeing far above and below for seeing near. The distance from the fixed far power above the lens to the near power fixed below the lens does not change suddenly, but a gradual transition between the two through the gradual change in refractive power. Compared with ordinary lenses, there are many advantages. The appearance of the lens is like a single vision lens, and the dividing line of the power change is not visible. Not only is the appearance beautiful, but more importantly, it protects the age privacy of the wearer, and there is no need to worry about revealing the age secret due to wearing glasses.

Since the change of the lens power is gradual, there will be no image jump. It is comfortable to wear and easy to adapt. So it is easy to be accepted. Because the degree is gradual, the replacement of the adjustment effect is gradually increased according to the shortening of the short distance. There is no adjustment fluctuation, and it is not easy to cause visual fatigue. Clear vision can be obtained at all distances in the visual range.

Such a pair of glasses meets the use of long-distance, near-use and various distances in the middle at the same time. It is especially good news for teachers, doctors, music workers, and computer operators, because these people not only need to see far and near objects clearly, but most of the time they also need to be able to see middle distance objects such as blackboards, piano scores, and computer screens. . This is not possible with any lens other than progressive lenses.
