Frequently Asked Questions

Red-light glasses are premium eyewear designed to filter out blue and green light wavelengths, allowing only beneficial red and near-infrared light to reach your eyes. This helps reduce eye strain, improve sleep quality, and support your natural circadian rhythm.

Our lenses use advanced optical technology to selectively block blue and green light (400-550nm) while transmitting red and near-infrared wavelengths. This mimics natural sunset lighting, signaling to your body that it's time to wind down and prepare for rest.

Red-light glasses are ideal for anyone exposed to artificial lighting in the evening, especially those who use screens before bed, work night shifts, or struggle with sleep quality. They're also beneficial for optimizing circadian health and reducing digital eye strain.

We use precision-engineered optical lenses with multi-layer coatings that provide superior light filtration without color distortion. Each lens is tested to ensure it blocks 100% of blue and green light while maintaining optical clarity and durability.

We offer free standard shipping on all UK orders. Orders are typically processed within 1-2 business days and delivered within 3-5 business days. Express shipping options are available at checkout for faster delivery.

We offer a 30-day satisfaction guarantee. If you're not completely satisfied with your glasses, you can return them for a full refund within 30 days of delivery. Items must be in original condition with all packaging included.
