Frequently Asked Questions
What are the main benefits of Anti Blue Light Lenses?
Anti blue light lenses are designed to filter out harmful blue light (wavelengths between 400-440 nanometers) emitted by digital screens. This helps reduce digital eye strain, prevents fatigue, and protects the retina during prolonged device usage.
What refractive index options are available for these lenses?
These lenses are available in three index options: 1.553, 1.597, and 1.667, allowing you to choose the appropriate thickness and weight based on your prescription needs.
What is HMC coating and what does it do?
HMC (Hard Multi-Coated) technology enhances the lens surface by improving hardness and wear resistance. It also provides basic water and oil resistance, making the lenses much easier to wipe clean and keep clear in daily use.
How does Blue Coating compare to Green Coating in light transmittance?
Blue coating lenses have a light transmittance of 96.8%, which is slightly lower than green coating lenses (98.6%). However, this minor difference does not impact daily visual performance and is highly sufficient for regular use.
Are blue coating lenses suitable for night driving?
Yes. Blue coating lenses are suitable for night driving as they help reduce reflections from screens and strong oncoming headlights, which improves overall visual contrast and clarity.
