Rising interest rates negatively impact National Vision through multiple channels: higher borrowing costs on the company's debt (0.81 D/E ratio), pressure on consumer discretionary budgets reducing willingness to upgrade to premium products, and valuation multiple compression for unprofitable growth retailers.

Not suitable for income-focused investors given negative profitability.
