Benefits of wearing blue light blocking glasses

1. Use blue light blocking glasses to relieve eye discomfort.

Excessive use of the device can cause computer vision syndrome or digital eye fatigue. Glasses with blue light filtering technology can enhance your concentration and reduce eye fatigue, thereby making your eyes feel less tired and improving work efficiency. Another way to reduce eye strain is to ensure that you stay away from the screen regularly.

2. Sleep better with blue light blocking glasses

One of the more surprising effects of touching the screen is that it may have a negative effect on sleep patterns. Blue light has a high energy frequency, which can increase alertness and delay the body's release of melatonin, which helps induce sleep. Generally speaking, we should all avoid using Blu-ray devices one to two hours before going to bed. Anti-blue light glasses can reduce the impact of blue light, allowing you to use your device before going to bed and still have a good night's sleep. However, the best option is to put down the screen before going to bed.

3. Reduce the possibility of AMD

Age-related macular degeneration (AMD) is the main cause of blindness. Anti-blue light lenses can help avoid or delay this situation by preventing blue light from affecting your eyes.

Computers, TVs, mobile phones, and tablets all emit blue light. Even with long-term exposure, the blue light emitted by these devices may not be enough to cause damage to the eyes or vision. However, further research is needed to confirm whether the blue light emitted from these devices is harmful. Experts are also uncertain whether blue light glasses can help symptoms associated with increased screen exposure. Ophthalmologists suggest that eye fatigue, headaches, and lack of sleep may be related to computer vision syndrome, rather than blue light exposure. For eye health, wearing blue light blocking glasses is not enough, we still have to develop good eye habits.

What Do the Numbers on Glasses Mean?

In this section, we will show you the glasses numbers meaning. These numbers on glasses frames are the measurements that indicate and describe the size of your eyeglasses frames, specifically:

1. The eye size number (it is the size of the lenses on your frame).
2. The bridge size number (the distance between the lenses).
3. The temple length number (it is the size of that part of your eyeglasses frame, which rests upon your ears).

The three numbers mentioned above are the key measurements that describe the glasses measurements of the frames in eyeglasses. For example, you will see three numbers like 51-17-145 at the temple of your glasses. These numbers help the optician to choose the best-fitted frame for your head size and facial features.

All of these three numbers are measured in millimeters. These variations in frame numbers are fitted by a skilled optician so that it should be best fitted, be comfortable and look good on the appearance.

Shorter lens beam

When you choose a glasses frame for kids, you must pay attention to that the lens beam must be short. The size of the lens beam stipulated by the national standard is 13~22mm. As a child, it should be controlled under 18mm. Otherwise, the position stability of the glasses will be poor.

Finally, they can not casually wear other people's glasses. The strength of each person's glasses, the distance between the optical centers of the two lenses, the length of the temple are different. So they can not casually wear other people's glasses.

What are pure titanium rimless glasses?

Pure titanium rimless glasses combine the advantages of pure titanium glasses with rimless glasses. Rimless frames are mainly focused on lightweight, reducing the pressure on the wearer and enhancing comfort. Moreover, rimless frames are not obvious either in appearance or in weight, which alleviates some of the distress caused by myopia. Pure titanium material increases this lightness to the extreme. Pure titanium frame has a uniform and natural color. It is not easy to fade, not easy to rust, and anti-allergy. It is the pursuit of high-end taste glasses lovers' first choice.

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.
