Definition
验光 is a separable verb (离合词) meaning 'to have an eye exam'. The verb 验 ('examine') and the noun 光 ('light; sight') can split to insert measure words, duration, or aspect markers — e.g. 验了一次光 ('had an eye exam once'). It's the standard term for the optometry procedure done at an eyeglass shop or clinic.
