Anti-fog lens cloth
Anti-fogging glasses cloth is composed of multiple layers of material pressed together, and the material absorbed a sufficient amount of antifogging agent. It can be directly wiped on any lens. Like spray anti-fogging agents, anti-fogging time is relatively short, and can not be wiped or washed. Long time use will affect the life of the lens. The range of lenses available is limited.

Is it a good idea to buy glasses online?
If the product is purchased from a reputable and trusted retailer, buying glasses online is just as safe as buying any other product online. Buying custom-made products, such as 'prescription glasses' online, is a bit more complicated than buying regular 'ready-made' glasses. All uploaded prescription glasses orders are reviewed and notified when serious errors are found in the prescription. All prescription glasses to be shipped are also carefully checked by quality control personnel to ensure that the glasses match the required prescription to the highest standard.
What Are Progressive Lenses?
Progressive lenses are designed for people who are over 40 years old. It is a blended multi-focal lens with distance correction at the top, intermediate in the middle, and reading at the bottom. The goal is for the lens to work how your eye naturally works to let you see things both close up and far away.
Progressive lenses are made with an hourglass shape so there is some blurriness on the outer edges, but since it gives you your full range of vision, it is generally better than a bifocal despite being similar.
What Are Progressive Lenses?
Progressive lenses have grown in popularity and are one of the most common solutions to treat vision loss that occurs with age or presbyopia. This eye condition occurs when the eye loses some of its flexibility and ability to adjust to clear seeing objects at different distances. Presbyopia often occurs among adults who are over age 40 and is very easy to correct with a proper and prompt diagnosis.
Progressive lenses are often used to correct this eye condition. Progressive lenses are a modern alternative to bifocal glasses, which provides two prescriptions in a single set of glasses. Bifocal glasses are a better solution than carrying around multiple pairs of glasses. Progressive lenses were developed to resolve some of those common issues and to provide better aesthetics. Progressive lenses provide a smooth transition and can accommodate up to three prescriptions and are a replacement for both bifocals and trifocals.
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.
What effect does a lens with the hard film have?
In order to improve the wear resistance of the lens, it is necessary to coat the surface of the lens with hard film. At present, silicon atoms are used to stiffen the membrane, that is, the stiffening solution containing organic matrix and inorganic superfine particles including silicon element is used to make the hard film have toughness and hardness at the same time. Because the common resin lens is far easier to wear than the glass lens, so the addition of hard film is mainly used for resin lens. It is usually applied to the front surface of the lens, and the anti-wear ability of the resin lens with the film will be enhanced a lot, and the light permeability will be strengthened.
