Healy Eames was first elected to Galway County Council, for the Oranmore electoral area, and served there from 2004-2007.

She was elected as a Senator by sitting TDs and councilors in 2007, and appointed the Fine Gael Seanad (senate) spokesperson on Education and Science. In 2011, she was appointed the Fine Gael Seanad Spokesperson on Social Protection and member of the Joint Oireachtas Committee on European Affairs and the Joint Oireachtas Committee on Education and Science. Healy Eames was the Fine Gael Seanad Spokesperson on Social Protection until July 2013. In March 2016, she announced her intention not to contest the 2016 Seanad election, and plan to resign from politics.
Healy Eames was expelled from the Fine Gael parliamentary party on 16 July 2013, when she defied the party whip by voting against the Protection of Life During Pregnancy Bill 2013. On 13 September 2013, she and six other expellees formed the Reform Alliance, described as a "loose alliance" rather than a political party.
A car belonging to Healy Eames was seized in Galway city on 2 July 2012 for failure to display a valid car disc. She told the Galway Advertiser: “I was using public transport up and down to Dublin and I had neglected the car tax. There is no excuse. I was completely in the wrong”. Healy Eames was then fined for boarding the Galway-Dublin train without a ticket on 12 July 2012, 10 days after her car was seized. She was convicted and fined €1,850 for the motor tax offence.
In March 2015, she attracted press attention for a tweet in which she claimed that were Ireland to legally recognise same-sex marriage, it could mean an end to the celebration of Mothers Day in the country. As evidence, she claimed that various U.S. states had banned Mothers Day and Fathers Day, referring to it as "political correctness gone mad". When critics pointed out that her claim regarding U.S. states was untrue, she retracted that statement, commenting that she meant to refer to a number of U.S. schools. In defending her comments, Healy Eames cited as her source Rense.com, a website run by Jeff Rense, a conspiracy theorist known for Holocaust denial, and criticised by the Anti-Defamation League. Critics in the Yes campaign accused her of employing scare tactics ahead of the May 2015 referendum on the issue.
In July 2015, during a Seanad debate on a bill to curb online freedom of speech, Healy Eames' referred to a "wiffycode" (actually meaning a Wi-Fi hotspot password). A clip of this and the accompanying hashtag "#wiffycode quickly went viral, and a parody mix was released by radio station Spin 1038. She later claimed that she was using the French pronunciation of Wi-Fi.
