Licensed optometrists in Washington State can test patients? visual acuity, prescribe eyeglasses, or contact lenses, prescribe visual therapy, and adapt prosthetic eyes.  With additional education requirements, a qualified optometrist may also use or prescribe some topical or oral drugs for therapeutic or diagnostic purposes.  To earn the right to apply topical drugs for diagnostic purposes, an optometrist must complete 60 hours of didactic and clinical instruction in general and ocular pharmacology, and receive certification from an accredited institution.  To earn the right to prescribe topical drugs for therapeutic purposes, an optometrist must complete the requirements above, as well as an additional 75 hours of instruction.  To use or prescribe oral drugs, an optometrist must meet the above requirements for use, and prescription of topical drugs, as well as complete an additional 16 hours of didactic and eight hours of supervised clinical instruction, and receive certification from an accredited institutionintuition.
 
In 2003, the Legislature expanded the optometry scope of practice to allow the range of drugs an optometrist may use or prescribe beyond topical drugs to include some oral drugs for diagnostic or therapeutic purposes, as well as injectable epinephrine for treatment of anaphylactic shock.  In 2015, the Legislature authorized optometrists to use, prescribe, dispense, purchase, possess, or administer Schedule II hydrocodone combination products.  The Board of Optometry (board) may include Schedule II hydrocodone combination products in its list of approved oral controlled substances and oral legend drugs.
 
Board of Optometry.  The board consists of three members of the examining committee for optometry, and two more optometrists appointed by the Governor. The optometrist members must be Washington State residents, must have been in active practice as a licensed optometrist in Washington for at least four years immediately preceding appointment, and may not have any connection with any optical supply business.
 
The board must develop and administer or approve a licensure examination.  The board must adopt rules and regulations to promote safety, protection, and the welfare of the public, to carry out the board's purpose, to aid the board in the performance of its powers and duties, and to govern the practice of optometry.
 
Sunrise Review.  In a December 2021 draft report, the Department of Health (DOH) conducted a sunrise review to expand the scope of practice for optometrists in Washington State.  DOH recognizes that all provider types should be able to practice to their highest level of education.  However, DOH found the submitted bill proposal as written to be too broad, and it does did not adequately describe what procedures would be allowed. DOH recommended the following changes to the bill proposal to ensure patient safety:

• restructure the bill to specifically enumerate the additional procedures rather than listing broad categories and allowing the board to further define those categories in rule;
• authorize the limited advanced procedures proposed by DOH as an endorsement to an optometrist credential, rather than making the expanded scope the baseline;
• include a requirement that clinical training on the advanced procedures include supervised hands-on experience with patients, rather than just laboratory experience;
• require the national examinations for advanced procedures including Lasers and Surgical Procedures Examination and Injections Skill Examination;
• clarify that the Legislature determines scope of practice;
• maintain the list of excluded procedures to ensure clarity on what is and is not allowable within the scope of practice of optometry; and
• maintain the provision allowing optometrists to administer inoculations for systemic health reasons if authorized by the state health officer.

Scope of Practice.  In addition to the existing scope of practice for optometry, the scope includes:

• the prescription and fitting of contact lenses for the purpose of altering refractive error or to treat eye disease;
• the prescription and provision of visual therapy, neuro-optometry rehabilitation, therapeutic aids, subnormal vision therapy, orthoptics, and other optical devices;
• the ascertainment of the perceptive, neural, muscular, or pathological condition of the visual system;
• the adaptation of prosthetic eyes;
• ordering necessary diagnostic lab or imaging tests including, but not limited to, finger-stick testing and collecting samples for culturing;
• dispensing of medication samples to initiate treatment is permitted; and
• removal of nonpenetrating foreign bodies, debridement of tissue by any means, epilation of misaligned eyelashes, placement of punctal or lacrimal plugs, including devices containing pharmaceutical agents implanted in the lacrimal system, dilation and irrigation of the lacrimal system, light therapy, and placement of biologic membranes.

The practice of optometry may include the following advanced procedures:
