First of all, the light transmittance of diving goggles is one of the important indicators to measure its optical performance. Lenses with high light transmittance can allow more light to penetrate, so that divers have a brighter vision underwater. This can not only improve the visual comfort during diving, but also help divers better observe the surrounding environment and improve diving safety.
Secondly, the refractive index of diving goggles also affects the visual experience of divers. The appropriate refractive index ensures that light is correctly refracted when entering the eye, thereby forming a clear image on the retina. If the refractive index does not match, it may cause blurred or distorted vision, affecting the judgment and operation of divers.
In addition, the anti-fog performance of diving goggles is equally important. Underwater, due to temperature differences and humidity changes, the lenses are prone to fogging. Lenses with good anti-fog performance can reduce the generation of fog, keep the field of vision clear, and thus enhance the diving experience.
The wear resistance of diving goggles is also a key factor affecting the diving experience. In an underwater environment, the lenses may be rubbed by hard objects such as sand and shells. If the wear resistance is insufficient, the lenses are easily scratched, which in turn affects the vision.
At the same time, the impact resistance of diving goggles glass cannot be ignored. During diving, the lens may be hit by accident, such as being touched by marine life or impacted by water flow. Lenses with strong impact resistance can better protect divers' eyes from injury.
Furthermore, the field of view of diving goggles glass also affects the diver's experience. Lenses with a wide field of view allow divers to more easily observe changes in the surrounding environment and improve alertness and safety during diving.
The optical performance of diving goggles glass has an all-round impact on the diving experience. Choosing diving goggles glass with high light transmittance, suitable refractive index, good anti-fog performance, wear resistance and impact resistance, as well as a wide field of view will greatly improve the visual experience and safety during diving.
