1. Three-layer lens structure: Inner double-layer anti-fog coating + intermediate optical PC substrate + outer iridescent electroplated sun protection coating. Inner hydrophilic anti-fog coating: Uses a fog-absorbing particle hydrophilic process to enhance the hydrophilicity of the lens, reducing fogging due to temperature differences and ensuring clear underwater vision; Intermediate high-strength optical PC lens: High light transmittance, impact and shock resistance, waterproof against chlorine corrosion in swimming pools; Outer iridescent electroplated layer (UV400 protection): Effectively blocks UVA/UVB ultraviolet rays, filters strong light and glare from the water surface on outdoor beaches, softens strong light to protect the eyes; a clear flat lens is also available for indoor pools. r

Panoramic widened lens: 30% wider field of view, reducing underwater blind spots and providing a wider field of view for diving and freestyle swimming. r
