Blue light is the high-energy light that comes from screens like your phone, computer, and TV.

Too much of it can strain your eyes, make them feel dry, and mess with your sleep. Lumadux glasses filter out the worst of it so your eyes feel better, especially at night.

Yes. Our lenses filter the most harmful blue light from screens, which helps reduce eye strain, dryness, and fatigue. You’ll still see clearly, just without the harsh glow and nasty side effects.

Absolutely! We now offer custom prescription options for Lumadux glasses.

Just select "Custom RX" and enter your prescription details at checkout, and we'll tailor your pair to perfectly match your vision needs, ensuring you enjoy blue light protection, superior clarity, and a flawless fit every day.

Even short screen time can cause eye strain and mess with sleep. Lumadux protects your eyes anytime you look at a screen, even for a few minutes.

Nope. Our lenses are clear and color-accurate. You might notice a slight warm tint at first, but it fades quickly. Everything still looks normal.

Most cheap glasses barely block blue light, feel flimsy and look ugly. Lumadux uses high-grade lenses, better materials, and actually works — plus we back it with a 30-day guarantee and 1-year warranty.

Our glasses block up to 40% of harmful blue light (380-500nm) and 99.9% of UV rays.

We find this to be the sweet spot offering balanced protection without compromising clarity. Anything beyond that would require a dark lens.

If you already use reading glasses, simply match your current strength. If you're new to readers, try our non-prescription (0) option. For personalized advice, consult your optometrist.

Our signature frames measure 55-18-140 (lens width, bridge, and temple length), designed for a comfortable, secure fit.

Our Holmes frames is larger.

Our lenses are clear with a subtle reflective blue hue on the outside, and a slight, necessary yellow tint on the inside to enhance blue light blocking.

Sharper, strain-free vision may help you react faster, though individual experiences can differ.

Most customers notice benefits on the very first day of use.

Absolutely. Our glasses work perfectly over contacts, offering additional blue light protection.
