Lens
In vision, light rays first pass through the cornea and then through the lens before reaching the retina at the back of the eye.
Yes, light can pass through the palpebral fissure, which is the opening between the eyelids. The amount of light that passes through this opening can affect the amount of light that enters the eye and contributes to vision.
Translucent refers to a material that allows some light to pass through but diffuses it in the process, making objects on the other side appear blurred. Opaque, on the other hand, describes a material that does not allow any light to pass through, blocking the view of objects on the other side.
A polaroid allows light to pass through it in only one plane. If both polaroids are aligned, they will allow light to pass through the same plane. Otherwise, each will allow light to pass through a different plane and the overall effect of the two polaroids is that it will not allow light to pass through them.
Glass is a common material that is transparent and allows light to pass through, enabling vision of objects on the other side.

The best light transmission for sunglasses to provide optimal vision and protection is around 15-30. This range allows enough light to pass through for clear vision while still reducing glare and protecting the eyes from harmful UV rays.

Transparent materials will always allow light to pass through, translucent materials will allow light to pass through as well but the light rays will be scattered. Opaque materials will not allow any light to pass through.

A material that blocks all light completely is called opaque. Opaque materials do not allow any light to pass through them, creating a complete barrier to vision.
Objects that don't let light pass through them are called opaque. These objects absorb or reflect light, preventing it from passing through. Materials like wood, metal, and cardboard are examples of opaque objects.
Light is a form of electromagnetic radiation that allows us to see objects. It travels in waves and is made up of particles called photons. Light is essential for life on Earth as it provides energy for plants through photosynthesis and enables vision in animals.
