30% or 60%? Find Your Blue Light Filtering Level

Your day may begin with emails on a laptop, continue with messages on your phone and end with a favorite show on your tablet. Screens have become part of almost everything we do—but not everyone uses them in the same way.

That’s why PERFECTSIGHT blue light glasses come in two filtering levels: a lighter, natural-looking option for everyday wear and an enhanced option for longer or evening screen sessions.

At the center of both options is our rare-earth blue light coating technology.

Instead of depending on a heavily colored lens, PERFECTSIGHT uses a specialized rare-earth coating to selectively filter blue light at 450 nm.

The coating allows us to offer meaningful blue light filtering while keeping the lens appearance more wearable. The result is a soft amber tone rather than the strong yellow or orange appearance often associated with traditional blue light blocking glasses.

Combined with anti-glare properties, the lenses are designed to soften distracting screen reflections and provide clear, comfortable viewing across laptops, monitors, phones and tablets.

But how much filtering do you actually need? That depends on how—and when—you use your screens.

For most daily screen routines, our Everyday Filtering lenses offer a balanced starting point.

They filter up to 30% of blue light at 450 nm and have a light tea-amber tint. The color is subtle enough for work, study, video calls and everyday activities while keeping your surroundings relatively clear and natural-looking.

Everyday Filtering may be right for you if your screen time includes:

Working at a computer during the day

Studying or attending online classes

Checking emails and social media

Streaming videos in your free time

Moving regularly between screens and daily activities

Think of this as the “wear it throughout your day” option: noticeable filtering without a heavy lens color.

Some days involve more than a few emails and a quick scroll. You might spend hours working across multiple monitors, editing late into the evening or relaxing with a long gaming session.

For those routines, PERFECTSIGHT offers Enhanced Filtering lenses.

These lenses filter up to 60% of blue light at a wavelength of 450 nm. The increased filtering level creates a warmer amber tint, making it more noticeable than the Everyday Filtering option.

Enhanced Filtering is designed for:

Extended computer use

Evening screen time

Long gaming sessions

Working with multiple monitors

Anyone who prefers a stronger visible filter

The warmer tint is part of the higher filtering experience. If you work with photography, graphic design or other tasks where precise color judgment matters, keep in mind that the Enhanced Filtering lenses will create a more noticeable color shift.

There is no single filtering level that works best for everyone. The right option comes down to your screen habits and how you want the lenses to look.

	Everyday Filtering	Enhanced Filtering
Blue light filtering	Up to 30% at 450 nm	Up to 60% at 450 nm
Lens appearance	Light tea-amber tint	Warmer amber tint
Color experience	More natural-looking	More noticeable warm shift
Best suited for	Everyday daytime Filtering	Longer and evening screen sessions

Choose Everyday Filtering if you want a lighter lens that fits naturally in daily life. Choose Enhanced Filtering if you spend longer periods in front of screens and prefer a higher filtering level.
