Reading Eicha is a major part of the aveilus of Tisha B’Av. Rav Moshe Shternbuch says (2:250) that since women are Chayav in all the halachos of aveilus of Tisha B’Av, they are also required to hear Eicha. If they can not go to Shul they can say it sitting on the floor in the privacy of their own home.
Since reading Eicha is part of the mitzva of mourning the Bais HaMikdash it is important for both men and women to understand the general meaning of Eicha. If you just read it without any understanding you haven’t accomplished the goal. Rav Shternbuch recommends to use a readily available translation. A woman who doesn’t understand anything at all and does not have access to a translation need not go through the motions of reading Eicha.
Just like the Halacha of Davening, if a woman is so busy with her family that she cannot find the time for Eicha, she is patur. Revach
