With winter approaching and shorter days ahead, you may feel it’s time to put away your sunglasses.  Opticians share why your sunglasses should become a year-round accessory.

  Yes, the light in winter can be just as harsh as the summer light and just because the temperature is cooler outside, doesn’t mean that the sun’s UV rays are less damaging.  For added eye protection, opticians recommend polarized lenses for your sunglasses.  In addition to UV protection, if you ski or travel to snowy areas in the winter, polarized lenses help reduce the glare from snow on roads and mountaintops keeping you safe.

How do polarized lenses work?

   A polarized lens acts like a filter or lattice which only allows the useful light traveling from the object viewed to reach the eye, while blocking all the glare caused by the scattered light traveling in many random directions. Objects then appear sharper. Colors are more vivid and in true natural proportion due to the removal of scattered white light.

Regular sunglasses, regardless of the cost, are only colored plastic or glass and cannot block out glare. These ordinary sunglasses just reduce the amount of visible light the eye sees, but the problem of glare still remains. Polarized sunglass lenses should be of ophthalmic quality – the same as is expected from lenses used in prescription eyeglasses.

Do you need a prescription for polarized lenses?

Polarized lenses are available to fit the requirements of all those who demand optical quality sunglasses. They can be purchased as plain lenses (without a prescription) or with your prescription in single vision, bifocals, progressives or trifocals.  Your optician can help you can choose polarized lenses for your fashion shades or sports sunglasses.
