In long-sighted (hyperopic) individuals, the eye focuses light behind the retina instead of directly on it. This can result in difficulty seeing close-up objects clearly. The condition can be corrected with eyeglasses or contact lenses that help focus light properly on the retina.
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
Depends on the type of plastic.
It will not change. Glass slows light but does not change it frequency.
Pupil
after pupil first light enters aqueous humour or pupil
what happens when light enters a polorizing filter?
Pupils "constrict" when light enters, and "dilate "when the lighting dims
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.

It reflects a rainbow pattern
When light enters a prism, it refracts into different colors due to the varying speeds of light in different mediums. This separation of colors is known as dispersion and creates a rainbow spectrum.
It changes, in accordance with the optical density of the medium.
Short and long sightedness are caused by the lens of the eye focusing the light either in front of or behind the retina. Glasses alter the path of light going into the lens to adjust for this.
Because the lens (translucent layer of membrane over the iris) is either too thick, or too thin, causing light to be reflected at the wrong angle. There are two kinds of vision impairment: Long Sightedness Short Sightedness
They're short-sighted. Yes, the term "Myopia" means short sightedness. This means that light entering the eye is focused in front of the retina rather than on it. The opposite term is "Hyperopia" which means long sightedness. This means the light entering the eye is focused behind the retina rather than on it.
The wavelength of light decreases as it enters a glass slab from air. This is because the speed of light is slower in glass than in air, causing the frequency of the light to remain constant while its wavelength decreases.
When light enters a new material, it may be absorbed, transmitted, or reflected depending on the properties of the material. Some of the light may also be refracted, which causes the light to change direction as it enters the new material. The speed of light may also change, which can lead to phenomena such as dispersion.
