Stock Incentive Plans	Stock Incentive PlansDuring the nine months ended September 30, 2023, the Company granted 451,425 performance-based restricted stock units (“PSUs”) and 712,218 time-based restricted stock units (“RSUs”) to eligible employees and non-employee directors under the National Vision Holdings, Inc. 2017 Omnibus Incentive Plan (the “2017 Omnibus Incentive Plan”). The PSUs granted in fiscal 2023 are settled after the end of the performance period (i.e., cliff vesting), which begins on the first day of our 2023 fiscal year and ends on the last day of our 2025 fiscal year, and are based on the Company’s achievement of certain performance targets. The RSUs granted in fiscal 2023 vest primarily in three equal annual installments.
