Cheap reading glasses can cause eye strain.
The optical quality of cheap reading glasses is often not as good as that of custom glasses for computer use and reading. Moreover, cheap reading glasses often offer no protection against the high-energy blue light emitted from computer screens and other digital devices.
Benefits of wearing blue light blocking glasses
-
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.

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.

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.
Pair Eyewear
Pair is designed for children. There are only a few styles of frames, but there are hundreds of colors and patterns on top of the frames, and the top of the frame base can change colors, from pure pink to rainbow tie-dye to NBA logos. Pair also makes limited-edition tops and works with major brands like Marvel and Harry Potter to create themed styles that allow you and your children to showcase your personality. Each frame starts at $60, including standard prescription lenses, and the frames cost $25.
Progressive lenses and single vision lenses
An optical lens that has only one luminosity on a single vision lens and does not have special functions.
The curvature of the front surface of the progressive lens increases continuously from top to bottom, and the refractive power increases gradually and continuously from the distance zone located on the upper part of the lens until the near zone at the bottom of the lens reaches the required near-use refractive power. A pair of glasses can be used. You can see far away, you can see close, and you can see objects in the middle distance.
Titanium frame machining is complicated.
The elastic modulus of titanium alloy is small, which is easy to produce large deformation, springback, distortion, and vibration in cutting, resulting in poor geometric shape and accuracy of the workpiece. As the surface roughness increases, the tool wear increases. The thermal conductivity of titanium alloy is poor and its thermal conductivity is small, 1/6 of that of 45 steel, so the high heat generated in processing cannot be effectively diffused. It is even harder to use titanium to make glasses. The frames are very thin and a lot of fine work is demanded. It's definitely a challenge for titanium, which is pretty difficult to work with. In addition, titanium alloy frames involve titanium alloy welding technology, which is more difficult.
Optical Stores Provide Customer Experience
Traditional single product marketing has been far from meeting the needs of customers. It is necessary to apply practical artistic aesthetics to the decoration design of physical eyewear stores, product packaging, and marketing planning, to increase customers' experience of the store, increase store goodwill, brand memory, interest in the product, and stimulating customers' consumption. In reality, most eyewear retail stores are making great efforts in product selection, product display, consumer experience, marketing activities, service methods, and other aspects. For example, the introduction of themed display scenes in traditional optical stores, the layout of bricks-and-mortar stores of e-commerce to increase consumer service experience, and so on have achieved good results.
Ray-ban Driving Glasses
Ray-Ban sunglasses, an international brand, were created in the 1930s, especially for the US Air Force, to block the fierce light at high altitude, with a very good UV protection function. Through the precise manufacturing and polishing process, Ray-Ban lenses are free of optical deviation and will not cause eye strain, headache or fatigue after wearing.
