Blue light blocking finished lenses and regular lenses differ mainly in the following aspects:
- Function: Blue light blocking finished lenses can effectively filter blue light emitted by electronic screens and the like. They usually also provide 100% UV protection, which helps reduce eye damage caused by blue light and alleviate visual fatigue. Regular lenses primarily function to correct vision, such as for myopia, hyperopia, or astigmatism. Their ability to filter blue light is relatively weak, and they cannot specifically protect against blue light.
- Lens Material and Craftsmanship: Regular lenses are generally made of resin or glass. Blue light blocking finished lenses, on the other hand, use special optical materials. In addition, their surfaces undergo special treatments, such as coating or adding blue light-blocking agents to the material, to achieve the blue light filtering function.
- Lens Color: Regular lenses are usually transparent and colorless. Blue light blocking finished lenses, due to the need to filter blue light, typically have a light blue or light yellow tint. However, some high-end products can achieve a very light base color or even be nearly colorless through technical means.
- Suitable Crowds: Blue light blocking finished lenses are suitable for people who frequently use electronic devices, such as office workers, students, and gamers. Regular lenses are suitable for various people who need vision correction, and are used in daily scenarios like reading, writing, and going out.
- Price: Since blue light blocking finished lenses adopt special materials and technologies, their prices are usually higher than those of regular lenses.
- Maintenance Requirements: The coating layer of blue light blocking finished lenses is sensitive to high temperatures and alcohol. When cleaning, neutral detergent should be used, and flushing with hot water or wiping with alcohol cotton pads should be avoided. Although regular lenses are more wear-resistant, resin lenses will also deform when exposed to high temperatures, and their maintenance requirements are relatively lower.
