The lens bends light that has entered the eye through the cornea and focuses it onto the retina at the back of the eye.

Several transparent medias do at some extend, made the light to bend, to slow the speed of light to a certain degree -or refracts-); water, paper, glycerin, immersion oil, glass (crown), glass (flint), zircon, diamond, lead sulfide
more the incoming light will be refracted (bend) in the material.
No, a light ray does not bend if it enters a glass block perpendicularly.
yes
A lens
Light could bend when it enters a prism. A prism is a transparent object such as glass.
A glass prism
They bend or refract
Refractive indexes of both the substances are same

Light bends, when it light travels at different speeds in different mediums. Hope that helps.
When light is directed at transparent materials, it bounces off of the particles and is refracted accordingly. This causes the light to bend according to the materials refraction index. The higher the refraction index of the material, and the thicker it is, the more it bends the light and separates the colors.
Mirror (uses reflection principle), transparent glass sheet (uses refraction principle),etc are the instruments which are used to bend light.
The liquid crystal forms little shutters that polarize the light. They need another permanent polarized light filter in front that is oriented 90 degrees different. This cancels the light completely and makes the display opaque. The Liquid crystal can be altered electrically. Contacts inside the glass envelope are a very thin, transparent layer of silver. The arrangement of the sliver contacts can make the segments of a number display, symbols or pixels.
change of medium causes light to bend

Light is affected by the media that it travels through. Even air will bend light. Glass and water certainly bend light.
