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.

Do kids need blue light blocking glasses?

1. American Ophthalmological Association

The American Ophthalmological Association clearly stated that it does not recommend any special glasses. The organization stated that there is no evidence that blue light from electronic devices can cause damage to the eyes. The discomfort that many people experience after watching electronic screens for a long time is due to symptoms such as dry eyes and even blurred vision caused by digital visual fatigue. The symptoms of using electronic products are related to how we use digital devices, not the blue light emitted from digital devices. There is currently no clinical evidence that blue light causes damage to the eyes, and measures to prevent blue light may be more harmful than blue light itself. It is too early to take preventive measures against blue light and may have unintended consequences.

2. British Association of Optometrists

The association believes that there is a lack of high-quality evidence to support the use of blue shaded glasses to improve people's visual performance, sleep quality, relieve eye fatigue, or protect macular health. There is no research on the effect of anti-blue eyeglass lenses on the health of the macula.

3. Chinese Journal of Ophthalmology

If the blue light is excessive, that is, the human eye is exposed to high-frequency and high-energy blue light, it will damage the rod cells. However, the rich blue environment with intensive exposure and the normalized environment are two different concepts. Therefore, it is unscientific to equate blue light with retinal damage. Individualized blue light protection guidance and recommendations should be put forward under different conditions such as different ages, health conditions, and working environments.

If you are in the hospital for optometry, it should be noted that there must be test glasses to try on, if there are no test glasses to try on, the data is not accurate.
