Shades of Winter By CHRISTINA PASSARIELLO Nearly every major fashion label has an eyewear line, thanks to a boom of licenses with companies such as Luxottica Group and Safilo. But the sheer number of choices -- from fashion to function -- can be blinding. We asked French eyewear designer Alain Mikli, whose sunglasses and prescription glasses are sold in two Alain Mikli boutiques in New York and 500 other optical stores in the U.S. and Canada, for his take on sunglasses from the most recent semiannual collection. The creator of the funky red glasses worn by the star of the sitcom "Ugly Betty," he says that, in winter, many wearers can get by with lighter lenses. Mr. Mikli shopped with us for sunglasses to wear now at the Lissac store on Rue de Rivoli in Paris.
