Secondly, for the vision correction center, a biz domain could be used for patient education materials and appointment scheduling systems. This would provide a streamlined experience for patients while reinforcing our brand as an advanced and technology-driven service provider.

Lastly, in the realm of cloud-based education, a biz domain could be utilized for e-learning platforms and online resources. This would allow us to reach a wider audience and offer our services globally.
