Rapunzel is the princess of your kingdom; besides, she is your best friend too. Every day she used to come home and both of you spend time plying, chatting, eating and so on. She hasn’t come for three days. Later you come to know that she suffers from cataract, a form of an eye-disease. You are not that sad as you were once; for you are an optometrist. Treat the girl with more affection. When she comes out of the hospital, a radiant smile should blossom on her face. Apply in very small amount of eye-drops to the eye-balls; apply to the both eyeballs. Now, take the sponge and clean the drops. Now conduct the vision test so as to find out what she is suffering from. Check her eyes with the laser and remove the dirt from the pupil. Find out the root cause of the problem by conducting the number test. At the end choose the appropriate lens that suits the girl.
