Do these glasses actually reduce eye strain?

Owners commonly report less tiredness after long screen sessions. The effect is modest and varies by person, so treat them as one aid alongside breaks and good screen habits.

Can I wear them over contact lenses?

Yes. They are plain non-prescription lenses, so they can be worn with contacts or on their own.

Are they for daytime use or only at night?

They work any time you are looking at a screen. Many people use them for evening phone and laptop time when blue light is most disruptive to sleep.

Do they come with a case?

The listing does not detail accessories. Check the box contents before ordering if a case matters to you.

How do they compare with prescription blue-light lenses?

These are a separate pair you put on for screens. Prescription lenses correct vision and block blue light in one frame, but cost more and need an eye exam.
