The plaintiff seeks in this declaratory proceeding a determination of the validity of a regulation promulgated by the Board of Registration in Optometry. The case is before us on a report, without decision, of a single justice. All of the facts alleged in the plaintiff’s bill are admitted by the defendant, and the parties have stipulated that these are ‘ all the material facts from which the rights of the parties are to be determined.”
The plaintiff is a registered optometrist authorized to practise optometry in this Commonwealth. The defendant is the board created by G. L. c. 13, § 16. On September 1, 1961, the plaintiff entered into a lease with G. E. M. of Boston, Inc. (hereinafter called Gem), under the terms of which he was to occupy a portion of Gem’s premises for use as an office for the practice of optometry. The proposed office is on premises where Gem conducts a “commercial or mercantile establishment.” This establishment is the primary business conducted on the premises. A regulation (No. 17) promulgated by the defendant in 1951 provides, “No optometrist shall conduct the practice of his profession in or on premises where a commercial or mercantile establishment is the primary business being conducted.” A controversy having arisen between the parties as to the validity of this regulation, the plaintiff brought this bill for declaratory relief. G. L. c. 30A, § 7. G. L. c. 231A.
I.
The plaintiff contends that the rule making power conferred on the board by G. L. c. 112, § 67, does not include the power to prohibit an optometrist from conducting his practice on premises where a commercial or mercantile establishment is the primary business being conducted. *131 Section 67 provides that “The board shall make rules and regulations governing its procedure, governing registration and applications therefor, and governing the practice of optometry. Said rules and regulations shall be consistent with the provisions of sections sixteen to eighteen, inclusive, of chapter thirteen and sections sixty-six to seventy-three, inclusive, of this chapter” (emphasis supplied). The plaintiff argues that the meaning of the words, “practice of optometry,” must be found in § 66, wherein it is stated: ‘ ‘ The practice of optometry, as referred to in sections sixty-seven to seventy-three, inclusive, is hereby defined to be the employment of any method or means, other than the use of drugs, for the diagnosis of any optical defect, deficiency or deformity of the human eye, or visual or muscular anomaly of the visual system, or the adaptation or prescribing of lenses, prisms or ocular exercises for the correction, relief or aid of visual functions.” It is the plaintiff’s position that the definition of “practice of optometry” in § 66 narrows the delegation of rule making power in § 67 to matters concerning the acts performed by optometrists relative to their patients, and concerning persons who are entitled to perform such acts. We do not agree. Sections 66 through 73B of c. 112 are entitled “Registration of Optometrists.” These statutes are concerned with the registration of optometrists (§§ 68, 69, 70, 71), and certain unlawful practices (§§ 72, 72A, 73A, 73B). By § 67 authority is given to the board to make certain further regulations. It was necessary that the profession of optometry, as distinguished from the roles of the optician and ophthalmologist, be clearly defined so that there would be no doubt as to whom these sections were applicable. This we view to be the sole purpose of § 66. “Practice of optometry,” as used in § 67, should, we think, be read without being limited by § 66. To restrict the delegation of rule making power in the manner suggested by the plaintiff would mean that the board (aside from regulations governing its procedure, registration, and applications therefor) was limited to making regulations concerning how the op *132 tometrist actually diagnoses and corrects Ms patients’ visual faculties. It is hardly likely that the Legislature intended such a result.
It is urged by the plaintiff that the language of G. L. c. 112, § 73B (inserted by St. 1938, c. 434, § 3), and its legislative history show that the Legislature reserved to itself the power to regulate geograpMcal location of optometrists’ offices by preempting the field. For reasons presently appearing, we are of opinion that the challenged regulation did not exceed the authority granted to the board in § 67. Section 73B reads, in part: “No person shall practice optometry on premises not separate from premises whereon eyeglasses, lenses, or eyeglass frames are sold by any other person; nor shall any person practice optometry under any lease, contract or other arrangement whereby any person, not duly authorized to practice optometry, shares, directly or indirectly, in any fees received in connection with said practice of optometry.” The latter part of the statute, involving a prohibition of the practice of optometry by a registered optometrist where fees are shared with an unregistered person or corporation, was discussed in

v.
Board of Registration in Optometry,
We find no merit in the plaintiff’s contention that the power exercised by the board in regulation No. 17 is an exclusively legislative power which cannot constitutionally be delegated. See
Ritholz
v.
Indiana State Bd. of Registration & Examination in Optometry,
*133 H.
The constitutionality of the regulation in question is challenged here on the ground that it is not within the police power of the Commonwealth to so limit the plaintiff’s right to engage in his lawful occupation.

That the practice of optometry may be regulated by requiring examination and registration is not open to dispute.
Commonwealth
v.
Houtenbrink,
While the challenged regulation does not in terms constitute a prohibition on advertising by optometrists, we are of opinion that a restriction against locating in premises with a primarily commercial enterprise is closely related to such a prohibition. The board could conclude that the presence of an optometrist in a commercial establishment of the sort operated by Gem would create the same evil as would advertising, i.e., mercantile practices resulting in lowered professional standards. 2 In both instances it is the public who suffer.
In
Williamson
v.
Lee Optical of Oklahoma, Inc.
The plaintiff argues that a ease may be imagined where an optometrist is located in a building occupied primarily by a bank, which is clearly a commercial enterprise. Under the regulation, it is urged, this could not be done. But it is impossible, so runs the argument, to advance any rational reason for believing that such a situation could endanger the public health or welfare. Whether the regulation would be constitutional as so applied is a question which does not concern the plaintiff; as applied to the facts in the present ease, the regulation is valid.
Commonwealth
v.
Brown,
Finally, it is argued that the proposed plan to locate an optometrist in a department store is of benefit to the public in terms of greater convenience. That may be so, but it is not within our province to pass upon the wisdom of the challenged regulation. See
Kay Jewelry Co.
v.
Board of Registration in Optometry,
A decree is to be entered declaring that regulation No. 17 is valid.
So ordered.
Notes
The plaintiff rests Ms argument solely on the Massachusetts Constitution, Declaration of Bights. He concedes that the regulation does not violate the Fourteenth Amendment to the Federal Constitution. We quote from Ms brief: “Because of the extent of the Supreme Court’s deference to the judgment of the States in matters of economic regulation, counsel do not believe a substantial question is raised in tMs ease under the Fourteenth Amendment.”
Despite what was said in
Wyeth
v.
Cambridge Bd. of Health,
“No person, firm, or corporation engaged in the business of retailing merchandise to the general public shall rent space, sub-lease departments, or otherwise permit any person purporting to do eye examination or visual care to occupy space in such retail store.”
