In one sentence

This law clarifies that optometrists, like physicians, can write prescriptions allowing drivers or passengers to use specific window glazing materials on vehicles if needed for medical reasons.

What it does

  • Adds 'optometrist' as a professional who may issue statements of medical need for vehicle window glazing materials.
  • Requires that these prescriptions state whether the condition is temporary or permanent.
  • Mandates that prescriptions specify the minimum percentage of light allowed to pass through the windows.
  • Sets an expiration date limit of two years on prescriptions unless the doctor notes the condition is permanent.
  • Allows drivers to use a prescription written for certain family members if they are driving specific vehicles listed in the document.

Who it affects

  • Optometrists who treat patients with vision-related medical needs
  • Drivers and passengers requiring window glazing due to medical conditions
  • Vehicle owners whose prescriptions cover their make, model, and license plate

Limits and unknowns

  • This law applies retroactively from July 1, 2025, and only covers prescriptions issued on or after that date.
