In our modern world, we're constantly exposed to blue light, whether from computer screens, phones, tablets or natural sunlight. While blue light is partly beneficial for our regulation of the sleep-wake cycle, excessive exposure can lead to eyestrain, sleep disorders and potentially accelerated retinal aging. Fortunately, Transitions® lenses offer an effective solution to protect your eyes from this harmful light.
What is blue light and why protect against it?
Blue light is part of the visible light spectrum, with wavelengths ranging from 380 to 500 nanometers. It is emitted by both artificial sources (screens, LED bulbs) and natural sources (sunlight). Prolonged exposure to this light can cause :
• Increased eye fatigue.
• Sleep disturbance by reducing melatonin production.
• Oxidative stress, which can contribute to early retinal degeneration.
How do Transitions® lenses work?
Transitions® lenses are photochromic lenses that automatically adjust to the surrounding light intensity. They darken in the presence of bright light, especially UV rays, and regain their transparency indoors. This technology provides effective protection against blue light in two ways:
1. Active indoor filtering: Transitions® lenses block some of the harmful blue light emitted by screens, even when they are clear.
2. Enhanced protection outdoors: when darkened in the sun, they block out an even greater proportion of blue light, and also protect against harmful UV rays.
The benefits of Transitions® lenses for your visual health
• Reduced eye fatigue: Less exposure to blue light means less stress for your eyes, especially for those who spend long hours in front of a screen.
• Better sleep: By filtering out blue light, these lenses can help preserve melatonin production and improve your sleep.
• Protection against premature retinal aging: Less exposure to oxidative stress means better long-term eye health.
• Convenient adaptation to all light conditions: No need to change glasses when moving from indoors to outdoors.
Are Transitions® lenses suitable for everyone?
Yes, these lenses are available for most visual corrections and can be adapted to all lifestyles. Whether you're a professional who spends long hours in front of a screen, an outdoor enthusiast or simply concerned about your eye health, they're an excellent choice.
Transitions® lenses offer intelligent, adaptive protection against harmful blue light, helping to improve your visual comfort and long-term health. By investing in these innovative lenses, you'll ensure better prevention of blue-light-related disorders, while enjoying optimal everyday comfort.
