Mixing contact lenses and cosmetics can be a messy situation.  Here are some tips from the American Optometric Association (AOA) that will help you keep your eyes safe while using cosmetics and contact lenses.

• Put on soft contact lenses before applying makeup.
• Put on rigid gas-permeable (RGP) lenses after makeup is applied.
• Avoid lash-extending mascara, which has fibers that can irritate the eyes, and waterproof mascara, which cannot be easily removed with water and may stain soft contact lenses.
• Do not use hand creams.
•  Remove contact lenses before removing makeup.
• Choose an oil-free moisturizer or lotions before applying contacts.  They can leave film on your lenses.
• Use hairspray before putting on your contacts. If you use hairspray while you are wearing your contacts, close your eyes during spraying and for a few seconds afterwards.
• Blink your eyes frequently while under a hair drier or blower to keep your eyes from getting too dry.
• Keep false eyelash cement, nail polish and remover, perfume and cologne away from the lenses. They can damage the plastic.
• Choose water-based, hypo-allergenic liquid foundations. Cream makeup may leave a film on your lenses.¹
