Motor vehicle window tinting; allow MS licensed optometrists to diagnose for purposes of a medical exemption authorizing.

SB 2453 amends Mississippi's window tinting law to allow licensed Mississippi optometrists to diagnose medical conditions that qualify for a tinting exemption, previously limited to physicians. This directly affects residents with light-sensitive conditions (like certain skin diseases) who need medical exemptions to legally use darker window tint. The bill expands the list of qualifying professionals who can certify these exemptions but maintains existing requirements: applicants must still obtain a free certificate from county tax collectors, provide a signed diagnosis from a qualified provider, and display the certificate on their vehicle dashboard. It does not change the exemption rules or light transmittance standards for tinted windows.
