Many things can make your eyes feel dry, gritty, or uncomfortable: air conditioning, heating, computer use, reading, some medication, wind or a reduction of tears your body produces - tears that help lubricate and nourish your eyes.
OPTIVE Lubricant Eye Drop advances dry eye relief by providing a dual-action formula that moisturizes the surface if the eye while also hydrating the areas where the dry-eye starts, giving your eyes long-lasting moisturizing protection.
