The working principle of driving glasses
The driving glasses are designed according to the polarized angle and radian of the lens and the principle of precision optics. It can only let the beneficial light pass through, and other light sources, like strong sunlight, car headlights, and other light sources are filtered, to eliminate the interference of external light, and avoid the appearance of eye-catching, dazzling, and other situations. That's basically how the driver glasses are designed.
Why are titanium glasses so expensive?
Pure titanium can guide the electron wave to produce ions so that the current tends to ionize, and positive and negative ions can reduce the harmful effects of the body's biological current chaos caused by electromagnetic waves. To the human body, it has a great health care role. It avoids fatigue, muscle stiffness, soreness, and other symptoms or problems.
How Should Glasses Fit?
You should check the placement of the bridge. The bridge is the small middle piece on the front of your frames that sits on your nose. This measurement is usually the middle number displayed on the inside of your temple. The bridge should rest comfortably on your nose without pinching or sliding off. A correctly fit bridge will also ensure your glasses sit properly on your face and your eyes are aligned appropriately within your lenses.
How should glasses fit? You need to consider the size of your lenses, which is essential to the proper function of your prescription, especially with the progressive lenses, because it ensures that there is enough space for the near, intermediate and distance zone powers of your prescription.
Adjust the nose pad
The height of the nose pad is adjusted by first holding the glasses with one hand and holding the nose pad with pliers with the other. Then the pliers are lifted up and the nose pad is moved down until the glasses are in the correct position on the face. The asymmetrical adjustment method is to first hold the frame of the eyeglasses with one hand, the other hand clamps the nasal plate with pliers. Then twist it in the direction of the correct tray position so that the surface of the tray is in contact with the two sides of the nose. Wrap one side of the lens of the glasses to be operated with a cloth first to prevent the screwdriver from slipping and scraping the lens during the operation. Don't scratch your glasses by adjusting your nose pad.
Geometric Clear sunglasses
The geometric shape of sunglasses is really novel, with the front and back of the two layers of design, to add a rich sense of line to the cheek. Choose individual character dyed-in pick eyebrow, matching again super short hair, individual and fashionable.
Contact Lens Materials - HEME Mixed Materials
Using HEMA as the matrix, other monomer components are added to improve the hydrophilicity, oxygen permeability, anti-precipitation, and other functions of the lens.
What material is the lens coating used?
The anti-reflection film material of glass lenses is usually magnesium fluoride. Because the coating process of magnesium fluoride must be carried out at more than 200℃, otherwise it cannot be attached to the surface of the lens. The resin sheet is not used. Since the 1990s, with the development of vacuum coating technology, the combined effect of film and lens has been improved. At the same time, high purity metal oxide materials like titanium oxide and zirconia can be deposited on the surface of the resin sheet through the evaporation process to achieve a good anti-reflection effect.
