"Most of the time it lasts for four days," Wade said. "This time, the effects are going into the third day. I'm doing everything with the doctors, but there are certain things you can't control."
Wade remains sensitive to light, but participated in Monday's practice wearing tinted glasses.
"My headache is gone, but my vision hasn't fully recovered," Wade said. "I'm not looking up much and I'm squinting still."
Wade's fashion statement produced some good-natured ribbing among the Heat's staff and his teammates.
"Dwyane is doing his best Danny Schayes impersonation," coach Erik Spoelstra said, referring to the retired 18-year veteran known for his on-court eyewear. "But he's here and he went through the practice."
Wade has stated he prefers not to play in glasses or goggles, though he acknowledged the migraines might force him to if his condition doesn't improve before Thursday night's game at New York.
Wade didn't care for the red-framed pair of glasses the Heat had lying around the facility on Monday, a sentiment echoed somewhat by teammate Chris Bosh.
"He has to take his precautions with his situation," Bosh said. "If his accessories are lacking, then he has to take the punishment. The red tint is a nice flavor, though."
