No. Eyes are not luminous. They observe or perceive light but they do not emit light. Luminous means "emit light." There are various species of animals, such as deer, cats, and dogs, whose eyes have the ability to reflect light which sometimes make them appear to glow in the dark as they reflect a flashlight, headlight, or other light that is shining in their direction. But even then, the eyes do not produce their own light so they are not luminous.
Because of its brightness and visibility from the naked eye.
The phrase "one eye is brighter than the other" suggests that one eye is more luminous or shining than the other.
It is luminous
Light from the flashlight reflects off the ball to your eye which enables you to see the ball.
Luminous.
It's non-luminous
Luminous could also mean 'full of light or illuminated'. For example: luminous hands of a clock. Here, luminous denotes shiny or that give light. In the example: luminous room; luminous indicates well-lighted. Something that is clear or easy to understand is also termed luminous. Fro example: luminous prose or luminous theory. Luminous could also mean inspiring, intelligent, or enlightened.
luminous is correct
Pls read "The Influence of Low-powered Family LED Lighting on Eyes in Mice Experimental Model" in life science journal and you will know most of them will damage eyes. Not depend on luminous intensity.
It's often possible to see non-luminous objects if you illuminate them with a source of light, such as a flashlight, a candle, or a drop of golden sunshine. No object absorbs all of the light that falls on it, so some light is always reflected from it, and some of that reflected light finds its way to your eye. Once any of the light falling on the object has reflected from it, it's very much as if the object were self-luminous.
luminous means that it gives light
It gives off light. That is what luminous means.
