You're probably comparing the IV of the chain with the vega of an individual options contract. Vega is the price component driven by total IV of an individual option in the above example. So IOW in that example, .0154 of the price is from vega. But the vega itself is 17.6%. Which means the expected price movement is 17.6% in either direction within 1 standard deviation from the current market price.
