Do these glasses actually block blue light?

They are sold as blue-light blocking, and most lenses in this category filter a modest share of blue light. Expect some reduction in glare, not a cure for eye strain.

Will the heart shape fit my face?

The heart silhouette is narrower than a standard rectangle, so lens coverage is smaller. Check the frame width against a pair you already own, especially if you have a wide face.

Are they prescription glasses?

No. They are non-prescription computer glasses. If you need vision correction, you would have to have prescription lenses fitted or wear them over contacts.

Can I wear them all day?

The light metal frame is fine for desk sessions, but the fixed fit and small lenses can feel tiring over many hours. Take screen breaks regardless.

How should I care for the gold frame?

Wipe the lenses with a microfiber cloth and keep them in a case. Store them folded, since the thin metal bridge and temples bend if pressed.

Are they a good gift?

Yes, if the recipient likes playful accessories. The heart shape is a statement, so it suits someone who wants fun glasses rather than a neutral pair.
