What is Backside Glarefree Coating for sunglasses?
Backside Glare-Free Coating on Sunglasses is an anti-reflective (AR) coating applied to the inside surface of the lenses to reduce glare that originates from light reflecting off the back of the lenses. This coating helps to improve the visual experience and comfort while wearing sunglasses, especially in bright environments.
How Does Backside Glare-Free Coating Work on Sunglasses?
- Prevents Reflection: When light enters the lenses from behind (for example, sunlight reflecting off a surface behind you), it can cause reflections on the back of the lenses. The backside glare-free coating reduces these reflections, ensuring that light is not redirected into your eyes.
- Improves Visual Clarity: Reducing these reflections makes it easier to see clearly without distractions from light bouncing off the lenses.
- Enhances Comfort: It reduces eye strain by preventing excessive glare, especially when you're in environments with bright, reflected light, such as at the beach, on water, or on snowy slopes.
Benefits of Backside Glare-Free Coating on Sunglasses
- Better Vision in Bright Conditions:
- The coating helps improve your vision in conditions where reflected light (from water, snow, or roads) is common.
- Less Distraction:
- It prevents reflections on the back of the lenses from causing discomfort or distractions, leading to a clearer view and more comfortable wear.
- Enhanced Aesthetics:
- The coating makes the lenses more transparent from the inside, allowing your eyes to be more visible, which is especially desirable for those concerned about aesthetics in photos or interactions.
- Improved Night Driving:
- When driving at night, it reduces reflections from streetlights, car headlights, and other light sources, making it easier to see the road clearly.
Who Should Consider Backside Glare-Free Coating on Sunglasses?
- Frequent Drivers: Reduces glare from headlights, streetlights, and reflections from the dashboard or windshield.
- Outdoor Enthusiasts: Ideal for those who spend time near water, snow, or sand where glare is a common issue.
- Photographers: Helps prevent reflections that could affect vision when photographing in bright conditions.
- Anyone Sensitive to Glare: If you're bothered by glare when wearing sunglasses, this coating can significantly reduce that issue.
Do All Sunglasses Need Backside Glare-Free Coating?
Not all sunglasses require this coating. However, it can be particularly beneficial in situations where you're exposed to high amounts of reflected light.
Care for Sunglasses with Backside Glare-Free Coating
- Clean Gently: Use a microfiber cloth and a gentle lens cleaner to avoid damaging the coating.
- Avoid Scratching: As with all AR coatings, be careful not to scratch the lenses, as this can affect the performance of the coating.
- Proper Storage: Always store your sunglasses in a case to protect them from damage.
Conclusion
Backside Glare-Free Coating on sunglasses offers a significant improvement in visual comfort and clarity by eliminating distracting reflections from behind. It enhances your outdoor and driving experience, particularly in bright, glare-prone environments. If you're frequently in such settings or suffer from glare-related discomfort, this coating is definitely worth considering for your sunglasses.
