Bifocal Reading Glasses for Women and Men

These lenses accommodate both near and far vision by incorporating a unique lower lens with an add vision value for reading and near vision, while also blocking 85% of harmful blue light. The photochromic technology automatically darkens the lens to help you adapt to changing light conditions.

The distortion-free lenses keep text sharp, even in your peripheral vision. The multi-layer coating, only 10um thick, increases the surface hardness of the lens to prevent scratches. If you encounter any issues with the product, you can contact the seller without hesitation, and they will provide you with the best service.

The photochromic lenses change color automatically based on the intensity of the sunlight, filtering reflected light and sunshine from the surface of water when fishing, and effectively cutting down glare to protect your eyes. The high-definition lens provides clear vision and reduces eye fatigue. The durable materials ensure the glasses can be used for a long time, and they also block some dust and wind to improve safety during outdoor activities.

However, it's important to note that the photochromic lenses may not change color very obviously under weak light conditions, and people may have different subjective experiences with the visual effects. If you have any problems after purchase, feel free to reach out to the seller.

It's worth mentioning that some windshields and window glasses can block some sunlight, which may limit the color-changing ability of the photochromic lenses.

The glasses are suitable for various occasions, such as driving through tunnels. When you enter a tunnel, the lenses that have turned dark under the sun outside will gradually lighten, helping you see clearly inside the tunnel. This can be safer than regular sunglasses with deep dark lenses, which may be too dark to see clearly in the tunnel.

The bifocal glasses feature premium photochromic lenses, comfortable adjustable nose pads, durable non-slip temples, and a lightweight frame for long-time wear. Some windshields may already block sunlight, so the lenses may not change color as much in those cases.
