1. Appearance: Coated swimming goggles have a layer of colorful film on the outside, resembling sunglasses. This coating adds privacy, as others can’t see your eyes, while uncoated myopic swimming goggles are clear and transparent.
2. Sunlight Protection: The coating on myopic swimming goggles effectively blocks strong sunlight and ultraviolet (UV) light, making them ideal for outdoor use.
3. Improved Vision: The coating reduces surface refraction and minimizes lens reflection, providing clearer underwater vision compared to uncoated myopic swimming goggles.

2. Choosing Between Coated and Uncoated Myopic Swimming Goggles

When selecting myopic swimming goggles, individual needs and usage settings are key. For indoor pools with stable lighting, non-coated myopic goggles are generally sufficient. However, for outdoor swimming, coated myopic goggles offer enhanced UV protection, and their appearance is often more stylish and professional.

3. Why Are Myopic Swimming Goggles Coated?

The natural light transmittance of standard lenses is approximately 91%, with some light being reflected off the lens surfaces. Coated lenses use advanced optical film and vacuum technology, applying a single or multi-layer optical film that enhances the lens’s reflective and light-transmitting properties. This coating can increase light transmittance to around 98%, improving clarity and reducing glare.

The primary benefits of coated lenses include:

• Reducing reflected light on the lens surface for clearer vision.
• Minimizing specular reflections and enhancing light transmittance.
• Providing comfort under bright light, reducing glare, and adding to the goggles’ aesthetic appeal.
