There are different refractive errors that are common and some of them are:
- Nearsightedness (myopia) makes far-away objects look blurry.
- Farsightedness (hyperopia) makes nearby objects look blurry.
- Astigmatism can make far-away and nearby objects look blurry or distorted.
- Presbyopia makes it hard for middle-aged and older adults to see things up close
<h3>What is Refraction?</h3>
This refers to the study of light phenomena that deflects when it passes through a medium in an oblique manner to another medium of a varying density.
Hence, we can see that there are everyday examples of refraction in simple terms which occurs and some of them are:
- Glass
- Human eyes
- Ice crystals
- Pickle jar
- Microscope, etc.
Hence, we can see that your question is incomplete, so I gave you a general overview to help you get a better understanding of the concept of refraction.
