1,000 volunteers will help more than 3,000 patients at this four-day health clinic that takes over Seattle Center.

Jordan Walker is trying on a few pairs of glasses and studying himself in a handheld mirror. He likes what he sees. Walker said he’s almost blind without glasses and he hasn’t had his eyes checked in two years.

“These are kind of simple," he said. "They fit my face and complement my eyes. I have nice blue eyes. Do you like my nice blue eyes?”

Optician Mike Sherman sits across from Walker and laughs at his joke. Sherman tells Walker after they get a few measurements that Walker will be done with his appointment.

Walker is taking advantage of the Seattle/King County Clinic that’s now in its sixth year. It’s happening on the campus of Seattle Center. In previous years, it took place in KeyArena. But since the building is currently under construction, the health clinic has moved into various performance venues.

The opera house, McCaw Hall, is now a medical clinic. The Cornish Playhouse serves as a vision clinic. That’s where Walker tried on different glasses. Exhibition Hall is now a dental clinic.
