Accommodative infacility

Accommodative infacility is the inability to change the accommodation of the eye with enough speed and accuracy to achieve normal function. This can result in visual fatigue, headaches, and difficulty reading.[1] The delay in accurate accommodation also makes vision blurry for a moment when switching between distant and near objects. The duration and extent of this blurriness depends on the extent of the deficit.[2]

The condition is commonly treated with vision therapy/orthoptics; one study found that 12 weeks of treatment had a significant effect on visual accommodation.[3]
