reading glasses designed uniquely for the group of people who have trouble in focusing on nearby objects, say, reading newspapers or surfing the Internet. And most wearers of reading glasses are thought of as the aged people that are prone to get far-sightedness which requires correcting and prescription reading glasses. Sometimes young people may suffer from far-sightedness as well and have to wear reading glasses. To put it specifically, wearers of reading glasses are those who get headaches and sore eyes after reading for a few minutes, those who have to squint while trying to read newspapers and watching what's going on the television set, those who hold books at arms length to read and those who have reached their 40th birthday.
