What MEM finding defines a high accommodative lag?

Explanation:
MEM measures how closely the eyes’ accommodation matches near task demand by looking at the lens power needed to neutralize the reflex. A positive value means the eye is under-accommodating (a lag), and the larger that positive value, the greater the lag. A lag of about 1 diopter or more is considered high, because the response falls well short of the near demand. So a finding of +1.00 D or greater best defines a high accommodative lag. Smaller positive values (like +0.25 D) indicate a mild lag, while negative values would indicate an over-response (lead), not a lag.
