Answer:
difficulty determining colors
Step-by-step explanation:
Cone dystrophy is the name given to a wide range of eye conditions. These eye conditions are all linked by a problem with a type of drum called a cone. Photoreceptors do not work from the day the child is born (stationary) or slowly stop working during childhood (progressive). This often leads to blurred vision, difficulty determining colors, and aversion to light (photophobia).
Cone dystrophies can affect different children in different ways. Most young children born with a stationary cone dystrophy feel that their vision is "normal". At first they assume that everyone else has the same vision as theirs, for they have never known anything other than their own visual world. They do not realize that other people see things differently.
