Regarding the comments: Q: Why don't my glasses change color? A: Please check the product introduction page, as indoor glass can block ultraviolet rays. The discoloration of the lenses relies on absorbing UV rays to change color. Test the glasses outdoors in the sun to see the color-changing effect.

Q: Why don't my glasses change color? A: In the product package, you will find a test light. You can use this light to test the discoloration of the lenses directly. You can also use the included card to test the anti-blue light function.

【LIFETIME WARRANTY】: We provide a worry-free lifetime warranty and friendly customer service. If you encounter any issues with your computer glasses, please do not hesitate to contact us. We will provide the best service until our customers are fully satisfied. You have no risk in trying our products!

Blue Light Test: These glasses are designed to block harmful blue light, whether you are working or using your mobile phone. The test image clearly shows that the dazzling light without the lens is significantly reduced when passing through the lens, protecting your eyes from the harmful effects of blue light.

Photochromic Test: Many customers have asked about the photochromic function of the lenses. The key is to test the glasses outdoors in the sun, as indoor lighting may not activate the photochromic effect. Once exposed to sunlight, you will see the lenses gradually darken, and they will automatically return to a transparent state when the light source is removed.

Some customers have asked why the lenses do not become as dark as traditional sunglasses. It's important to understand that color-changing glasses are not the same as sunglasses. While they cannot achieve the same level of darkness, they still provide effective sun protection and blue light blocking capabilities. Additionally, we will provide a pair of polarized sunglasses as a complementary gift, so you can use them when the photochromic effect does not meet your needs in bright sunlight.

We hope you all have a great shopping experience with us. Our commitment is to always strive for the best in every product we offer.
