Product Description

Introducing our groundbreaking UV420-cut lens.

----With our pioneering UV+420cut technology, this lens is engineered to filter out harmful UVA & UVB rays while also providing a robust shield against high-energy visible light (HEV light) within the critical 400nm-420nm range. This ensures your eyes receive the most comprehensive and advanced protection available.
---Recent scientific advancements highlight the vital importance of protecting your eyes from UV and HEV light, which are crucial in preventing cataracts and defending against age-related macular degeneration (AMD).
---Remarkably, even on overcast days, as much as 60% of UV rays can penetrate through the clouds, with 20%-30% occurring during rainy weather. Our blue cut lens provides unwavering all-weather protection, effectively safeguarding your eyes under any conditions.

Discover the unparalleled advantages of our blue cut lens, meticulously crafted to promote optimal eye health and comfort.

1. The blue cut lens is expertly designed to efficiently block short-wave high-energy blue light emitted by various electronic devices and LED displays, thereby reducing eye strain and discomfort linked to prolonged blue light exposure.

2. By significantly minimizing blue light's interference with melatonin secretion at night, our blue cut lens enhances sleep quality, fostering a more restorative and rejuvenating rest.

FAQ

Q: Is it true that avoiding glasses will worsen myopia?
A: Absolutely, forgoing glasses can lead to increased eye strain, potentially exacerbating myopia.

Q: Can myopia be cured?
A: Myopia, a permanent condition, is akin to the natural elongation of the eye axis, similar to how height cannot be shortened. Once it occurs, it is not reversible.

Q: Will wearing glasses affect our children's growth in height?
A: Children's growth is shaped by multiple factors, such as reading habits and visual health. Selecting the appropriate eyewear, like Advanced Joythink Blue Blocking Eyeglasses with Anti-Blue Light Lenses, can significantly slow the progression of myopia, promoting not only enhanced eye health but also supporting their overall developmental growth.

Q: If my vision is clear, should I still wear glasses?
A: Eyeglasses serve the crucial function of harmonizing eye accommodation and convergence. This balance plays a pivotal role in preventing visual fatigue and maintaining proper eye alignment, ensuring your vision remains sharp and your eyes stay in peak condition.

Q: Is it necessary to wear glasses continuously?
A: For those who have matured physically with minimal eye strain, glasses with prescriptions below 200 degrees are recommended mainly for extended distance or close-up activities. Conversely, if you are still growing or experience significant eye strain resulting in quick fatigue and a prescription over 200 degrees, it is advisable to wear glasses consistently to safeguard your visual health and comfort.
