The optical industry is big business in France; government subsidies mean even fashion prescription frames warrant a reimbursement should your health insurance cover eye care. Needless to say the industry has decided to profit from this generosity, with the city’s many optical boutiques falling in to three distinct categories: independent boutiques selling some fantastically unusual designer frames (Voyeurs, Optique St Honoré or Marc le Bihan); big chain stores offering great service and discounts (Grand Optical and Alain Afflelou); and department stores stocking a wide range of internationally recognised brands.

Few outlets will carry out eye testing on site, as the law dictates all tests must be performed by a qualified ophthalmologist. Tests cost around €45 and are refundable through the social security system for residents. Optical boutiques, however, provide plenty of other services including after-sales service, repairs and custom-building of both prescription and sunglasses. Grand Optical and Alain Afflelou will also run the occasional buy-two-get-a-third-pair-free offer on prescription sales.

Sales of sunglasses, while no match for prescription glasses, are also growing in France thanks to the abundance of fashion styles available in a wide array of stores. The dominant big fashion brands such as Gucci, Dior, Chanel, Marc Jacobs are available in both independent boutiques, speciality chain stores such as Solaris, and department stores. Prices start at around €100 and head upward of €500 for exclusive frames from high fashion brands like Chanel and Hermes. Those looking to economise might try H&M or Zara, where stylish frames come with a less startling price tag. For a custom look, head to Oakley’s store on rue du Pont Neuf, where buyers can put together their own pair of sunglasses, selecting from a range of frame and lens combinations. True fans of vintage should make their way to Réciproque in the 16th arrondissement, where an entire boutique is dedicated to luxury, vintage accessories, including sunglasses.
