Definition of refract in English:

refract

verb rɪˈfraktrəˈfrækt

[with object]

1(of water, air, or glass) make (a ray of light) change direction when it enters at an angle.
（水、空气或玻璃）使（光线）折射
the rays of light are refracted by the material of the lens
光线经镜片材料而折射。
Example sentencesExamples
- They cut glass, they refract light into perfect hearts-and-arrows, and they have superlative fire and brilliance.
- The cornea and the crystalline lens refract light that enters the eye.
- Not only is the roof above them made of glass, it is also filled with water, further refracting the light received in the public spaces below.
- The image passes through the lens, which further refracts the light through its anterior and posterior curvatures.
- Sparkling glass goblets and mugs refracted the light just as the silver reflected it.
- Metamaterial research is an emerging field that uses manmade substances to alter the way materials refract light or electromagnetic radiation.
- The rays were detected by a calcium sulfide thread that glowed slightly in the dark when the rays were refracted through a 60-degree angle prism of aluminum.
- In De Natura Locorum he gives a diagram which shows light being refracted by a spherical glass container full of water.
- The wavelength of light affects how much it is refracted on entering the atmosphere, with red light refracted the most and blue least (as in rainbows).
- Color is important: one sees the reds, tans and browns of skin color, the blue of water and the wavy white lines of light refracted through the water.
- The hotter, denser air refracts the light coming from the horizon and the viewer sees an image of the sky near the horizon.
- A light ray is refracted when it passes from one medium to another at an angle and its speed changes.
- It acted like a prism on the setting sunlight striking it, refracting the light in much the same way as a crystal would.
- Spectacles and contact lenses refract the light before it enters the eye, helping the eye to focus objects sharply.
- Ideally we would like to refract the shadow ray too, but mathematically this is a much more difficult problem to solve.
- The cornea and lens refract the incoming light rays to focus them on the retina at the back of the eye.
- This is because of particles in the air refracting the light.
- In particular, this initial work has demonstrated the enormous potential for a new generation of lenses, which function, of course, by refracting the rays of incident waves.
- The regional variation of ocean depth acts as a lens to refract the waves, just as a lens refracts light.
- When the temperature difference is large enough, the warmer air refracts the light and amazing images can be seen.
1. 1.1 Measure the focusing characteristics of (an eye) or of the eyes of (someone)
  测定眼睛的屈光度，验光
