Do not think that we only need to protect our eyes on sunny days, or in summer sunny season, we also need to protect our eyes from excessively using the computer and watching TV. Sometimes when we watch a lot of TV, our eyes become blur. It makes our eyes strain to see. It happens to me. That's why I'm wearing contact lens or eye glasses from http://www.eyesave.com I got recently. It really helps to consult our eye doctor early once we feel strange of our eyes.
