Step 1
Use of a diverging lens in front of the eye
Answer
The visual disorder described indicates that light is focusing in front of the retina, which typically suggests a condition known as myopia (nearsightedness). To correct this issue, a diverging lens (concave lens) can be used. This type of lens helps to spread out light rays before they enter the eye, effectively moving the focal point further back to align with the retina, allowing distant objects to be seen more clearly.
