The difference between myopia glasses that protect against blue light and those that do not is whether they can effectively filter out blue light. The following will introduce the characteristics and advantages and disadvantages of these two glasses in detail.
Myopia glasses that do not protect against blue light
Myopia glasses that do not protect against blue light usually can only correct vision, but cannot filter out harmful blue light. Blue light belongs to a type of high-energy visible spectrum, with strong penetration, and can easily pass through the cornea and lens of the eye and directly shine on the retina, which may cause eye fatigue, dryness, visual fatigue and other problems.
And long-term exposure to excessive blue light may also increase the risk of eye diseases such as macular degeneration.
Myopia glasses that protect against blue light
Myopia glasses that protect against blue light can filter out harmful blue light through special coatings or materials, reducing eye fatigue and discomfort.
Such glasses can usually filter out about 30% to 50% of blue light, which can effectively reduce eye fatigue and dryness, and reduce the potential risks to the eyes from long-term exposure to blue light.
It should be noted that although anti-blue light glasses can filter out some blue light, they cannot completely eliminate harmful blue light. In addition, the filtering effects of anti-blue light glasses of different brands and models will also be different, so you need to choose products with reliable quality.
In general, anti-blue light myopia glasses can better protect the eyes, reduce eye fatigue and dryness, and reduce the potential risks to the eyes from long-term exposure to blue light when buying myopia glasses. Therefore, it is recommended that people choose anti-blue light products as much as possible when buying myopia glasses to protect eye health.
