The Big Eyes conferences will bring together an international group of experts to review the current state of the art in the study of the high redshift universe and discuss how best to use giant telescopes to learn about it. Specifically, we aim to address the following questions:

• What potentially transformative observations will be enabled by giant telescopes? What capabilities are required?
• What are the key synergies between giant telescopes and other facilities? What are the areas and topics where a concerted effort will yield far superior results than the sum of all parts?
• What theoretical or observational work is needed in preparation for first light? What are the limitations in our understanding that need to be overcome?
• What calculations are required in order to make testable predictions and interpret the results of future astronomical observations?

It is extremely important to consider these questions now, while the plans for giant telescopes can still be influenced, and there is still sufficient time to carry out preparatory theoretical and observational work that will be needed to make the most of the large investments in these facilities. In order to facilitate attendance and reduce travel costs, we will hold three coordinated conferences, one each in America, Asia, and Europe.
