The first thing that Valoy saw when she put on color-blind corrective glasses was green - the vibrancy（活力） of the grass and tree - and later，the brilliance of red in stop signs and flowers.Valoy says it's unbelievable and she has struggled with certain topics，especially the painting class in school and she would even paint the ocean purple before that.
   Valoy wasn't diagnosed with red-green color blindness until the fourth grade. "For the past 17 years，I've lived in a 'black and white movie'，" the recent Louis E.Dieruff High School graduate says.But not anymore.The transformative moment all started with a public speaking class Valoy took.After she made an informative speech about growing up with her color deficiency （缺陷），her teacher，Sandy Kile，was inspired to teach the class a more important life lesson.
   Kile made a suggestion that the class should reach out to companies that produced corrective glasses to see if they would donate a pair to Valoy.While Kile encouraged Valoy to write a description of living in a world with mostly shades of grey and brown，her classmates wrote accompanying statements about why she needed the glasses. "I didn't expect much for that，" Valoy says. "Professor Kile truly believed it was going to happen but we were not sure."
   It wasn't so surprising when the first company turned down their request.Then，the class received reply from the founder of Pilestone Inc.，offering Valoy and six other community members his glasses for free. "We started this business by trying to make some difference to people，" founder Ben Zhuang says.
   Valoy is grateful to Kile and her classmates for their efforts.But Kile says that she is very glad the students have the chance to realize the significance of lending a hand to those in need，and that being able to aid Valoy in changing her life is something she will never forget the rest of her life.
