About Cookies on Alcon Websites
What is a cookie?
Cookies are small text files that are sent to your computer when you visit a website. Cookies on Alcon websites do lots of different jobs, like letting you navigate between pages efficiently, storing your preferences and generally improving your experience of a website.
The EU Directive 2009/136/EC states that we can store cookies on your machine, if they are essential to the operation of this website, but that for all others we need your permission to do so.
Alcon websites can use some non-essential cookies. We do not do this to track individual users or to identify them, but to gain useful knowledge about how the websites are used so that we can keep improving them for our users. Without the knowledge we gain from the systems that use these cookies we would not be able to provide the service we do.
The types of cookies we use
If you decide to set the language, font-size or specific version of the website (e.g. high-contrast), we use “user interface customization cookies.” Once set, you do not need to specify your preferences again on another visit to the website.
If you use parts of the website that require registration to access content, we will place an “authentication cookie” on your computer. This allows you to leave and return to these parts of the website without re-authenticating yourself.
If you have Adobe Flash installed on your computer (most computers do) and you use video players, we store a “flash cookie” on your computer. These cookies are used to store data needed to play back video or audio content and store the user’s preferences.
Alcon likes to understand how visitors use our websites by using web analytics services. They count the number of visitors and tell us things about the visitors’ behaviour overall – such as identifying the search engine keywords that lead the user to the website, the typical length of stay on the website or the average number of pages a user views. For this purpose we place a “first party analytics cookie” on your computer.
We may also use services such as Google Analytics to track web statistics. In this case, Google will place a “3rd party cookie” on your computer. This is also the case when we use Google Maps.
