Why should you clean the eyeglass case?
Although the eyeglasses case is used less, it can not be separated from the glasses. If it is not cleaned for a long time, it will affect appearance and carry a lot of bacteria.
What to consider when buying eyeglasses?
The size of the frame should match the pupil distance so that the edge thickness of the lens is thinner and more comfortable to wear. The size should be proportional to the size of the face. The upper edge should not be higher than the eyebrow and the eyebrow should not be visible in the lenses. The shape of the frame should match the shape of the face and skin tone to meet aesthetic requirements. The rectangular face should choose a circular arc or arc transition frame. An inverted triangle face shape should choose one with a lower wide edge.
What Are the Disadvantages of High-Index Lenses?
This section will show high index lenses disadvantages.
- High index lenses are made from a chemical synthetic blend that’s created through a special manufacturing process. So, high index lenses are expensive than regular lenses. In fact, the price may be more than double that of the traditional counterparts.
- High index lenses can be more brittle than their traditional counterparts and may also be more prone to scrapes and scratches. This can impact their overall durability.
- High index lenses are more reflective than regular lenses, which can make them less effective for brightly lit work environments, outdoor use and nighttime driving on busy highways.
- High index lenses have greater potential for distortion, particularly in your peripheral vision because the high index lenses have a higher Abbe value than prescriptions made from standard plastic or glass.
Who should wear blue light glasses?
Teenagers, middle-aged and old people need to wear blue light glasses. The lens of a teenager is clear, pure, and still developing. Their eyes are less resistant to blue light than adults and are more vulnerable to long-term exposure to blue light, which can promote the development of myopia. Teenagers study more nervous, are free to love to play computer games, love to watch TV programs. Blue light damage can be said to be everywhere. As a result, teenagers are among the biggest victims of blue light. Macular degeneration is a common disease in the elderly, usually occurring after the age of 45, and the incidence increases with age. Blue light can accelerate the progression of macular degeneration, especially in patients following cataract surgery. Blue-blocking glasses are still the best preventative measure.
Adjustment of the angle of the nose pad
For the angle of the nose pad, you can apply torque in the horizontal or vertical direction according to the deformation needs. It can be held in the proper part of the nose pad with needle-nose pliers, and the torque can be applied at a certain angle in the vertical plane or horizontal plane to achieve the purpose in accordance with the deformation needs. In the time of repeated actions, in order to prevent the welding place of the nose pad and the glasses ring from breaking due to repeated stress deformation, you can use your fingers to apply external force at the welding place to change the deformation position and play the purpose of protection.
What kind of light is blue light?
Blue light is light of a certain wavelength. In the sunlight, including red light, orange light, yellow light, green light, blue light, indigo light, and purple light, blue light occupies a place. The wavelength of blue light is less than that of red light but greater than purple light. The energy intensity is also different, and the blue light is relatively less strong than red light. People must rely on the 'macula' to perceive light. The macula is a 'pearl' hidden in the fundus and the most important photosensitive part of the fundus. The macula can look at objects, generate electrical signals, and transmit the signals to the brain so that people can see the things in front of them clearly. Strong light shines directly on the eyes, and it is likely to cause damage to the macular structure at once.
