The eyeglass has a refracting effect that bends the path of light into your eye at the right angle.
It is called absorbed light!
The fog is called a colloidal solution. When light is shined through this colloidal solution, the light scatters in all direction because of the substance contained in this solution type.
When light changes direction as it passes through a boundary.
They are light travels in a straight line and light cannot pass through opaque objects./ some light cannot pass through translucent objects.
There are many objects that no light can pass through, although of course, it depends on what type of light you're talking about. The name of the type of object that visible light cannot pass through is called opaque.
Light travelling through a concave lens will spread out. In most optical systems that use a concave lens, such as a telescope that needs to magnify the focal plane image, this is a desirable effect.
If light travels through an object, it is still called light. If you want to specify, you might say "light travelling through an object".

Bend it
Any change in the refractive index of the medium through which the light is travelling causes refraction of light.
Eyeglasses help by focusing the light through the cornea, the clear part of the eye just above the iris (colourd part of your eye).On to the back of the eye called the Retina which is photo sensitive. They can correct the light when it focus too far past the retina, far sighted (hyperopia). Or when the light focus too far in front of the retina, near sighted (myopia).
Beam of light
Eyeglasses work by bending light rays in the eyes of those who can't see well so that they reach the back of the eye properly (called the retina). When the light rays reach the appropriate part of your eyes you see better.
towards the normal
The velocity of light (and other electromagnetic waves) depends on the medium through which it is travelling.
