Va. Code § 51.5-61
The Board for the Blind and Vision Impaired is continued. The Board shall consist of seven members who shall be appointed by the Governor for terms of four years. No person shall be eligible to serve more than two successive terms, provided that a person heretofore or hereafter appointed to fill a vacancy may serve two additional successive terms. Vacancies occurring on the Board shall be filled by the Governor for the unexpired term. All appointments hereunder shall be made without reference to party affiliations, but solely on account of the fitness of the appointees to discharge their duties as members of the Board. The membership of the Board, however, shall at all times include four persons who are blind. Four members of the Board shall constitute a quorum for the transaction of any lawful business. Annually, the Board shall elect one of its blind members as chairman, who shall preside at its meetings and shall have power to call meetings when he deems it advisable.
