Peo. Ex Rel. Watson v. House of Vision





Appeal from the Appellate Court for the First District; heard in that court on appeal from the Circuit Court of Cook County; the Hon. Walter P. Dahl, Judge, presiding.


Rehearing denied January 28, 1975.

On July 6, 1965, the People, on the relation of John C. Watson, Director of the Department of Registration and Education, filed a complaint in the circuit court of Cook County seeking to enjoin the defendant, House of Vision, Inc., a large optical dispensing company, from continuing its practice of allowing employees not licensed as optometrists to fit customers with contact lenses. The plaintiff contended that the acts involved in such fitting constituted the practice of optometry within the meaning of section 3 of the Illinois Optometric Practice Act (Ill. Rev. Stat. 1965, ch. 91, par. 105.3).

Over six years later, in October of 1971, the case was finally tried. At the close of the plaintiff's case, the trial judge concluded, as a matter of law, that the acts performed by the defendant did not constitute the practice of optometry. He therefore granted the defendant's motion for judgment in its favor and dismissed the complaint. The Appellate Court, First District, affirmed (16 Ill. App.3d 487), and we granted leave to appeal.

Section 3 of the Act provides:

"The practice of optometry is defined to be the employment of objective or subjective means, or both, for the examination of the human eye and its appendages, without the use of drugs, medicine, or surgery, for the purpose of ascertaining any departure from the normal, measuring its powers of vision, and adapting lenses or prisms, ocular exercises, visual training, or any other method other than the use of drugs, medicine, or surgery, for the aid thereof. A person shall be deemed to be practicing optometry within the meaning of this Act who in any way advertises himself to be an optometrist, or who shall employ any means for the measurement of the powers of vision or the adaptation of lenses or prisms for the aid thereof, or who shall practice or offer or attempt to practice optometry, as herein defined, either on his own behalf or as the employee of a person, firm, or corporation, whether under the supervision of his employer or not, or who shall use testing appliances for the purpose of measurement of the powers of vision or diagnose any ocular deficiency or deformity, visual or muscular anomaly of the human eye or prescribe lenses, prisms, or ocular exercise for the correction or relief thereof, or who holds himself out as qualified to practice optometry. Nothing in this section shall be interpreted to prevent a person from acting as an assistant under the direct supervision of a person licensed by the State of Illinois to practice optometry or medicine and surgery, or to prohibit visual screening programs conducted by charitable organizations acting in the public welfare under the supervision of a committee composed of persons licensed by the State of Illinois to practice optometry and persons licensed by the State of Illinois to practice medicine and surgery." Ill. Rev. Stat. 1965, ch. 91, par. 105.3.

Simply described, the procedures followed by the defendant's employees with respect to contact lenses are as follows:

The customer brings in a normal spectacle prescription from an opthalmologist or optometrist on which the prescribing doctor has noted that it is "O.K." to fit the patient with contact lenses. The spectacle prescription contains the refractive (i.e., corrective) power of the lens for each eye, and sometimes also the vertex distance (i.e., distance of the spectacle lens from the eyeball). These prescriptions are not sufficient by themselves to fabricate a contact lens. They give no indication of the shape of the wearer's cornea, on which the contact lens must fit. This determination is made by the defendant's employee.

The first step in this procedure is the measuring of the approximate spherical curvature of the wearer's cornea. This is done by using an optical analytical device known as a keratometer. Because the keratometer is incapable of measuring an irregular cornea, this process is only the starting point for a fitting. Three keratometer readings are taken and averaged together, after which the fitter uses a chart to translate the result into a specific lens shape. He then selects a trial lens of this shape and places it on the wearer's cornea.

A contact lens, when properly fitted, is designed to rest on the tear layer covering the eye and on the outer layer of the cornea, which is called the epithelium. The epithelium is a tissue which acts as a protective covering for the cornea. To maintain its normal structure, function, and metabolism, the epithelial tissue requires a constant supply of oxygen. Normally, the cornea receives oxygen directly from the air through diffusion by the tear layer. But since a "hard" contact lens is not permeable, it must be designed to permit adequate tear flow underneath it in order to supply the epithelial cells it covers with oxygen. If it does not do so, these cells will be altered or die.

To determine proper tear flow, the fitter places a clear, nontoxic chemical, fluorescein, in the wearer's eye. He then examines the part of the eye covered by the contact lens with a magnifier equipped with an ultraviolet light which causes the fluorescein to glow green. By observing the depth of the fluorescein color the fitter determines whether there is proper tear flow behind the lens and what its rate of circulation is. He also determines whether any part of the trial lens is too tight or too loose on the cornea. There is no machine or chart to aid the fitter in reading these fluorescein patterns, which may be misinterpreted for a number of reasons. This is a skill which is acquired through training and experience.

Based upon his evaluation of the fluorescein patterns, the fitter may then select a trial lens of a different size and repeat the process. When he has finally determined a lens of the proper curvature to fit the cornea, he fills in an order form supplied by the manufacturer of the contact lenses. On this form the fitter writes in the spectacle prescription supplied by the prescribing doctor and, if indicated, the vertex distance. He then uses a transposition chart to convert these figures into an "adjusted" prescription, after which he notes the curve of the trial lens finally selected. The trial lens curve and the adjusted spectacle prescription are then converted by means of an arithmetic computation to the final power of the contact lens. The fitter may vary this power to a small degree to compensate for the refractive effects of the tear layer underneath the lens, as observed through the fluorescein patterns.

After the lenses have been manufactured, the customer returns to have the finished lenses fitted to him. At this time the fitter repeats his fluorescein pattern test and, if it appears satisfactory, gives the customer a wearing schedule. Two weeks later the customer returns and is questioned by the fitter regarding his reaction to the lenses. Complaints by the customer may include such things as a burning sensation from the lenses, sensitivity to light, pain, blurred vision, foggy vision, inability to read, and other matters. These comments aid the fitter in determining whether the lenses should be redesigned or whether the customer simply has not worn them properly. After the customer's subjective comments have been elicited, the fitter makes an objective examination of the cornea, both with and without fluorescein, to determine the fit and to check for any pathological conditions such as scratches, staining, stippling, or swelling which would indicate faulty lens design. After this examination, the customer is advised to make an appointment with his eye doctor within the following two or three weeks. This medical checkup will, therefore, normally only occur after the customer has been wearing his lenses for several weeks, unless the fitter notices damage to the eye at the first examination and refers the customer immediately to an eye doctor for treatment.

The plaintiff contends that these procedures, when viewed in their entirety, amount to the "adaptation" of lenses for the aid of the powers of vision. The defendant attempts to make a detailed semantic and logical rebuttal of such an interpretation. Neither party, however, mentions what we consider to be a significant indication of legislative intent, viz, the 1946 Attorney General's opinion regarding the applicability of the almost identical language of the 1945 Optometric Practice Act to the fitting of contact lenses. This opinion was issued to the Director of the Department of Registration and ...
