Bright, like all laser. It is about as bright as a low power laser pointer. It is usually a class one laser and can not hurt you, but make sure you check it's class before opening the printer, though I would not suggest opening it in the first place.
A projector for images for both transparent and opaque objects. It shines a bright light on an object in a box and a lens projects the image in a darkened room.
Some rubies are opaque but these are considered to be low in value. A ruby that is high in value should be almost transparent and should have bright coloring.

Dark field microscopy improves contrast by illuminating the specimen with oblique light, helping to visualize transparent or unstained samples that would otherwise be difficult to see under bright field microscopy where the specimen appears transparent against a bright background. Dark field microscopy enhances visualization of small particles, living organisms, and thin specimens due to the increased contrast and detail provided by the technique.
"Transparent moon" likely refers to an optical illusion where the moon appears to be translucent due to atmospheric conditions or weather phenomena like ice crystals or thin clouds in the sky. It is not physically transparent but can give the illusion of being so.
Neon is typically seen as a bright reddish-orange color when it is in its gaseous state and used in neon signs.
Bright field microscopy is a basic technique where light is transmitted through a specimen with little contrast, resulting in a bright background. The specimen appears dark against the bright background, making it suitable for observing stained samples or transparent objects. This technique is commonly used in biological studies to visualize cells and tissues.
A human eyelid is not transparent of course. But some animals like snakes have permanently sealed transparent eyelids which protect their eyes from foreign materials. Frogs also have transparent eyelids to protect its eyes while swimming in water.
