Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings.
If you disable this cookie, we will not be able to save your preferences. This means that every time you visit this website you will need to enable or disable cookies again.
These cookies allow our websites to remember information that changes the way the site behaves or looks, such as your preferred language or the region you are in. For instance, by remembering your region, a website may be able to provide you with local weather reports or traffic news. These cookies can also assist you in changing text size, font, and other parts of web pages that you can personalize.
Loss of the information stored in a preference cookie may make the website experience less functional but should not prevent it from working.
Most Google users will have a preferences cookie called 'NID' in their browsers. A browser sends this cookie with requests to Google's sites. The NID cookie contains a unique ID Google uses to remember your preferences and other information, such as your preferred language (e.g. English), how many search results you wish to have shown per page (e.g. 10 or 20), and whether or not you wish to have Google’s SafeSearch filter turned on.
We use security cookies to authenticate users, prevent fraudulent use of login credentials, and protect user data from unauthorized parties.
Process cookies help make the website work and deliver services that the website visitor expects, like navigating around web pages or accessing secure areas of the website. Without these cookies, the website cannot function properly.
For example, we use a cookie called 'lbcs' which makes it possible for Google Docs to open many Docs in one browser. Blocking this cookie would prevent Google Docs from operating correctly.
We also use one or more cookies for advertising we serve across the web. One of the main advertising cookies on non-Google sites is named 'IDE' and is stored in browsers under the domain doubleclick.net. Another is stored in google.com and is called ANID. We use other cookies with names such as DSID, FLC, AID, TAID, and exchange_uid. Other Google properties, like YouTube, may also use these cookies to show you more relevant ads.
Sometimes advertising cookies may be set on the domain of the site you're visiting. In the case of advertising we serve across the web, cookies named '__gads' or '__gac' may be set on the domain of the site you're visiting. Unlike cookies that are set on Google's own domains, these cookies can't be read by Google when you're on a site other than the one on which they were set. They serve purposes such as measuring interactions with the ads on that domain and preventing the same ads from being shown to you too many times.
Google also uses conversion cookies, whose main purpose is to help advertisers determine how many times people who click on their ads end up purchasing their products. These cookies allow Google and the advertiser to determine that you clicked the ad and later visited the advertiser's site. Conversion cookies are not used by Google for personalized ad targeting and persist for a limited time only. A cookie named 'Conversion' is dedicated to this purpose. It's generally set in the googleadservices.com domain or the google.com domain (you can find a list of domains we use for advertising cookies at the foot of this page). Some of our other cookies may be used to measure conversion events as well. For example, DoubleClick and Google Analytics cookies may also be used for this purpose.
We use Google AdWords Remarketing to advertise trigger across the Internet. AdWords remarketing will display relevant ads tailored to you based on what parts of the TriggerApp website you have viewed by placing a cookie on your machine. THIS COOKIE DOES NOT IN ANYWAY IDENTIFY YOU OR GIVE ACCESS TO YOUR COMPUTER. The cookie is used to say "This person visited this page, so show them ads relating to that page." Google AdWords Remarketing allows us to tailor our marketing to better suit your needs and only display ads that are relevant to you.
Websites often collect information about how users interact with a website. This may include the pages users visit most often and whether users get error messages from certain pages. We use these so-called ‘session state cookies’ to help us improve our services, in order to improve our users’ browsing experience. Blocking or deleting these cookies will not render the website unusable.
These cookies may also be used to anonymously measure the effectiveness of PPC (pay per click) and affiliate advertising.
For example, we use a cookie called ‘recently_watched_video_id_list’ so that YouTube can record the videos most recently watched by a particular browser.
Google Analytics is Google’s analytics tool that helps website and app owners to understand how their visitors engage with their properties. It may use a set of cookies to collect information and report website usage statistics without personally identifying individual visitors to Google. The main cookie used by Google Analytics is the 'ga' cookie.
In addition to reporting website usage statistics, Google Analytics can also be used, together with some of the advertising cookies described above, to help show more relevant ads on Google properties (like Google Search) and across the web and to measure interactions with the ads we show.

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.
