(dissenting):
The eminence of the District of Columbia Court of Appeals in the judiciary is underscored both by the statute conferring our jurisdiction to reexamine its judgments1 and by our rules indicating the conditions under which we will undertake to exercise it.2 We conduct such reviews only as a “matter * * * of sound judicial discretion” for “special and important reasons.” 3 Our many refusals to grant appeals from the court’s decisions attest our recognition of the authority which normally should attach to its pronouncements on matters of purely local law.
Yet there are situations in which a sensitivity to our statutory responsibilities demands that we take a further look at litigation after it has progressed through the Court of Appeals. Included are cases involving “a question of substance not theretofore determined by this court,”4 or “a question of general importance,” 5 or “a question of substance relating to the construction or application of statutes or municipal ordinances or regulations, * * * which has not been, but should be, settled by this court.” 6 Even as to the review of these our action is judgmental, of course, and it cannot be doubted that many falling within the narrowly circumscribed category defined in the court’s opinion 7 are unlikely to survive our evaluation in terms of the applicable criteria. Some may, however, although what is involved is the interpretation of a local regulatory law,8 and I feel that this is one that should. Accordingly, I respectfully dissent from the court’s disallowance of this appeal.9
In the District of Columbia Court of General Sessions, the petitioner-optician 10 was charged with the practice of optometry because, in the fabrication of contact lenses on an ophthalmologist’s11 *1327prescription, he made the measurements and performed the fittings incidental to that process.12 Whether that constituted optometric practice depended upon the meaning properly to be ascribed to legislation enacted in 1924,13 about two decades prior to the advent of contact lenses. We are told14 that, as a matter of standard practice over more than a century, persons requiring eyeglasses have been referred by physicians to opticians; who make and fit the glasses and then return the patient to the referring physician for final examination and approval. We are also informed that this general procedure has been in vogue for about 20 years where contact lenses rather than spectacles are the corrective device.15 Petitioner lays claim to a course of conduct conformable with these long standing customs in this branch of the medical profession.16
As the Court of General Sessions read the statute, “an optician may fit contact lenses only when supervised by a physician or an optometrist.” In determining “the degree and quality of supervision that is required,” it held that “a professional need not be physically present when an optician measures the curvatures of the eyes or fits contact lenses.” But, it continued,
“ * * * the actual physical presence of a professional during contact lens adaptation may be dispensed with only if there is a close and continuing relationship between professional and technician and an assurance of professional review as soon as the technical work is completed. * * * [A]n optician who is not operating in the physical proximity of a professional may complete the fitting of contact lenses only after he has previously ascertained or arranged that the patient will be able to see a professional (either an ophthalmologist or an optometrist) as soon as that fitting has been completed.”17
The Court of Appeals, however construed the statute differently.18 While not precluding “an optician from grinding, or fabricating contact lenses in accordance with a complete prescription furnished by a doctor, and delivering the lenses to the doctor for fitting,”19 it held “that the actual fitting of contact lenses is the adaptation of lenses within the meaning of our optometry statute”20 *1328whether or not the patient is re-referred to the prescribing professional.21
The Court of Appeals’ decision affects a wide range of vocational interests which have not been, but which desire to be, heard before the curtain is finally rung down.22 It has a solid impact on ophthalmologists and opticians alike in the traditional division of functions relative to the fabrication of contact lenses, and possibly eyeglasses as well.23 Largely because of the doubt it casts upon the legitimacy of other customary relationships, it may affect the medical profession more generally.24 And I am left in the dark as to whether and in what degree these modifications may involve the visual health of the community.
The question whether and under what conditions the statute prohibits opticians from fitting contact lenses would be one of first impression with us.25 Its substantiality is manifested not only by the circumstance that the two courts through which the case has journeyed reached significantly different conclusions, but also by the wide divergence in judicial decision in other jurisdictions.26 Moreover, petitioner has imparted a constitutional dimension to the scope of his grievance by his challenge to the statute’s specificity and his related claim that in the circumstances it did not give fair notice of the acts made punishable.27 I do not say that the decision of the Court of Appeals is wrong, but only that *1329we should be surer as to whether it is correct. I would allow this appeal in order that we may fully examine this perplexing problem and, for the benefit of all concerned, endeavor to put it to rest.

. The case is before us on petitioner’s motion for reconsideration of this panel’s disallowance, upon the same split in the vote, of his petition for appeal.
. Petitioner is an optician, with training as a contact lens technician, who has been engaged in practice for more than 20 years, mostly in the District of Columbia. He has been licensed to practice optieianry in New York. The District of Columbia does not require the licensure of opticians. See note 11, infra.
. “An ophthalmologist is a duly licensed physician who specializes in the care of the eyes. An optometrist examines eyes for refractive error, recognizes (but does not treat) diseases of the eye, and fills *1327prescriptions for glasses. The optician is an artisan qualified to grind lenses, fill prescriptions, and fit frames.” Williamson v. Lee Optical of Oklahoma, 348 U.S. 483, 486, 75 S.Ct. 461, 463, 99 L.Ed. 563 (1955).
. The process, detailed in the opinion of the Court of Appeals, Fields v. District of Columbia, 232 A.2d 300 (1967), includes measurement of the corneas, ascertainment of the curvature of the lenses, physical fitting of the lenses, and a determination as to whether they fit properly. A change in the prescribed power of the lenses may become necessary in consequence of a change in curvature to enable a suitable fit.
. “The practice of optometry is defined to be the application of optical principles through technical methods and devices in the examination of the human eye for the purpose of determining visual defects, and the adaptation of lenses for the aid and relief thereof.” D.C.Code § 2-501 (1967 ed.). The unlicensed practice of optometry is made a misdemeanor by D.C.Code § 2-502 (1967 ed.), under which petitioner was convicted.
. By the motion of the Medical Society of the District of Columbia for leave to file a memorandum as amicus curiae in support of the petition for reconsideration. See note 9, supra and note 22, infra.
. This comes from the source cited in note 14, supra.
. See, however, note 17, infra.
. Finding, however, that petitioner “adapted contact lenses on a wholly independent basis, without the requisite professional supervision, guidance, and control,” the court held that he had engaged in the practice of optometry.

. Id. at 306 n. 21.
. Id. at 305.
. Id. at 306.
. Memoranda as amici curiae in support of petitioner’s plea for reconsideration, see note 9, supra, have been filed by the Medical Society of the District of Columbia, which has a membership of approximately 2,400 doctors of medicine licensed to practice in the District of Columbia, through its Section on Ophthalmology, which represents those specializing in the care and treatment of the eye; the Guild of Prescription Opticians of America, Inc., a nationwide association of practicing opticians; the Guild of Prescription Opticians of Washington, D. C., Inc.; and the Contact Lens Society of America, Inc., representing more than 300 firms engaged in the craft of contact lens fitting on prescription and under direction of licensed medical personnel, a number of which member firms are so engaged in the District of Columbia.
. See notes 14 and 15, supra, and related text.
. Licensed physicians and surgeons are exempted from the operation of the legislation in question. D.C.Code § 2-520 (a) (1967 ed.). The Healing Arts Practice Act § 43(b), 45 Stat. 1326 (1929), D.C.Code § 2-134(b) (1967 ed.), exempts “laboratory technicians,” a category some of the amici contend embraces those who customarily have fitted contact lenses on the prescription and at the direction of licensed physicians and surgeons. Additionally, there are cases holding that an optician may fit contact lenses when acting under the direct supervision of legally qualified personnel. See, e.g., Kelley ex rel. Michigan Board of Examiners in Optometry v. Peterson, 4 Mich.App. 612, 145 N.W.2d 386, 388 (1966); State ex rel. Reed v. Kuzirian, 228 Or. 619, 365 P.2d 1046, 1050, 88 A.L.R.2d 1284 (1961).
. We have dealt with the optometry statute on only two occasions. Evers v. Buxbaum, 102 U.S.App.D.C. 334, 253 F.2d 356 (1958); Silver v. Lansburgh & Bros., 72 App.D.C. 77, 111 F.2d 518, 128 A.L.R. 582 (1940). Upon neither did we touch the question presented by this case.
. See the cases collected in Annot., 88 A.L.R.2d 1290 (1963). While there are differences in the statutory provisions these decisions undertake to construe, the conflict of authority is clear. And not without moment is the fact that the Court of General Sessions, and as well the Court of Appeals, Fields v. District of Columbia, supra note 12, 232 A.2d at 306, suggested the desirability of congressional consideration of the problem.
. There appear to be only two criminal cases in this area. In New Jersey State Board of Optometrists v. Reiss, 83 N.J. Super. 47, 198 A.2d 816 (1963), the conviction of an optician was upheld, but there, unlike here, the licensing statute specifically prohibited “fitting contact lenses.” 198 A.2d at 820. The court in Commonwealth v. Stemet, 21 Pa.Dist. & Co.2d 295 (1959), had a reasonable doubt whether the measurement of the curvature of the eye in order to grind contact lenses came within the prohibition of the statute, and it found the defendant not guilty of practicing optometry without a license.
