BROOKLYN - Dozens of elementary and middle school students are getting a free eye screening today.

About 60 students from P.S. 335, M.S. 584 and M.S. 130 will be screened individually by eye doctors. If it is determined that a child needs glasses, he or she will receive them for free thanks to OneSight, a global vision care non-profit. 

Out of about 500 students initially pre-screened a few weeks ago, 120 were found to need some sort of extra vision care.

Organizers of the event say something like this is a necessity in every school. OneSight is working to open self-sustaining vision centers in Brooklyn and the Bronx.
