Customization Blue Block Sunglasses Lenses Amber Blue Light Blocking Lenses

Blue light blocking lenses are functional lenses designed to prevent blue light from stimulating the eyes. They are widely used due to the increasing prevalence of digital devices. 

Definition and Function

Blue light blocking lenses can effectively isolate ultraviolet rays and radiation. They reflect or absorb harmful blue light through surface coating or adding blue - light - blocking agents to the lens substrate, thereby reducing damage to the eyes. They are suitable for use when viewing computers, TVs, or mobile phones. Blue light with a wavelength between 415 and 455 nanometers is harmful short - wave blue light, which is the main target of protection.

Benefits

• Alleviating Eye Fatigue: Prolonged exposure to blue light can cause symptoms of digital eye strain, such as headaches, blurred vision, and dry or burning eyes. Blue - light - blocking lenses can reduce these discomforts.

• Protecting Retinal Health: Excessive blue - light radiation can cause chronic photodamage to the retinal pigment epithelium cells. Wearing blue - light - blocking lenses can help protect the retina to a certain extent.

• Improving Sleep Quality: Blue light can inhibit the secretion of melatonin. By blocking blue light, especially in the evening, blue - light - blocking lenses can help regulate the body's biological clock and improve sleep quality.

• Color Perception Balance: Compared to red - tinted blue light blocking lenses, amber lenses provide a better balance in color perception. The lighter amber tint allows for more natural color vision while still blocking harmful blue light, making them suitable for use in situations where some color discrimination is required, such as in the early evening when people may still be engaged in various activities.
