There are a few types of machines that can help screen for vision problems. One is an eye chart. This device prints out a series of lines, which the person looks at to see if they can see any errors. There are also devices called retinal cameras that take pictures of the back of your eye. These pictures can be used to determine if you have any vision problems.

There are also machines that use a special light to test your vision. These machines use a pattern that is difficult to see, but is still present on some images. If you can't see the pattern, then you have a problem with your vision.

There are different types of vision screening machines that doctors and optometrists use to diagnose common vision problems. Here's a look at each type: 

-Refractor: A refractor is the most common type of vision screening machine. It uses a lens to magnify an image of objects on a screen. This is used to check for common problems such as nearsightedness or farsightedness. 

-Objective lens: An objective lens uses a mirror to direct light onto an object. This is used to check for problems such as myopia or cataracts. 

-Sphincter machine: A sphincter machine uses a camera to take pictures of the back of the eye. This is used to diagnose diabetic retinopathy, macular degeneration, and other conditions that affect the back of the eye.

Vision screening machines come in different types, so it’s important to know what you’re looking for before making a purchase.
