Short sighted people see a blurry image of their surroundings. Objects appear unclear and lacking details.
Lack of details
A short sighted person sees objects without a lot of their details. This is why Short sighted people usually fail to read text from a distance as they can’t figure out the details.
A short sighted person will hardly be able to recognize people from a distance. While in most cases a short sighted person will notice the other person he will usually fail to tell who he is.
Small objects might not be seen
Short sighted people can have a problem seeing small objects. Many short sighted people can’t locate their glasses on a messy desk as they don’t notice it. This is why they try to locate it using their hands.
Short sighted people can have problems telling the difference between objects from a distance. For example a person can have a problem telling whether an object is a dog , a cat or a plastic bag.
Short sighted people can have a problem seeing the boundaries of certain objects. A window in a building might not be seen well by a short sighted person. In more serious cases the window might not be noticed.
Close objects appear clearly
Many short sighted people can see a close object clearly. This distance depends on the degree of the short sight. (See Is Virtual Reality Bad for Your Eyes?)
A short sighted person can’t read text from a distance. A short sighted kid will hardly see anything on the blackboard especially if he were sitting in the back.
Darkness increases the problem
A short sighted person will have a bigger problem seeing things at night as objects become more unclear. A short sighted person might fail to see a hole in the ground. (See How Virtual Reality (VR) affects the eyesight?)
