Eyewear is slimming down, lightening up — and getting a dose of high-tech.

Pastels, blush tones and translucents are replacing bolder fluorescents and richer colors for spring, according to eyewear firms exhibiting at International Vision Expo East at the Javits Center in New York from March 14 to 17.

Oversize silhouettes are shedding some of their prior heft, as frames become thinner and shapes — ranging from round to cat-eye — are shrinking somewhat in size. With their new look, fashion sunglasses are also adding more technical elements, such as polarization on colored lenses.
