Note:
One, the frame size should not be too large
"Teenagers with glasses, it is good to choose plastic frames or lightweight titanium eyeglasses frames, and the size of the frame should not be too large, taking into account the width of the face. The closer the frame size is to the actual pupil distance of the eye, the better. This avoids the prismatic effect of excessive inward movement of the lens' center of gravity due to oversized frames, which can cause discomfort."
Two, lens material
The choice of lenses is even more important. Teenagers with good choice of light weight, unbreakable resin lenses. If you are engaged in sports, you should choose PC lenses (polycarbonate) with excellent impact resistance. This is good for teenagers who are in the developmental stage. Nowadays, there are many kinds of resin lenses, so you can choose the right one according to the refractive power of your eyes.
There are two options for optometry: 1. general optometry in optical stores; 2. medical optometry in specialized hospitals
The general optometry process is generally: computerized optometry - (dilated pupils) - comprehensive optometry
The general optometry process is generally: computerized optometry - (dilated pupils) - comprehensive optometry - trial wear, the measured result is in the optometric distance (generally 5m) visual acuity of 1.0 degrees, there is no comprehensive assessment of binocular vision, easy to make the wearer of the glasses, visual fatigue, glasses degree increase and other negative effects.
While medical optometry is based on the comprehensive function of the human eye, it is comprehensive, precise, and provides a scientific basis for the wearer to wear glasses that are both comfortable and can also play a role in health care.
I, focus
Conventional optometry: wear glasses after the optometric distance (usually 5m or 33cm) clear vision
Medical optometry: wear glasses not only clear vision, but also see far and near are comfortable and long-lasting
The second content of the optometry
Content of the optometry
Conventional optometry: computerized optometry, equipment is not complete
Medical optometry: on the basis of conventional optometry, the determination of the dominant eye, binocular adjustment balance test, eye adjustment function check, eye position and eye concentration and dispersion function check, stereoscopic examination, comprehensive optometry.
Three, optometry prescription
Conventional optometry: the pursuit of the clarity of vision after wearing glasses, the choice of correction degree has a certain degree of arbitrariness
Medical optometry: comprehensive basic eye examination, refractive state examination and the patient's visual function of both eyes examination results, comprehensive consideration to come up with the most suitable corrective program. MASTER, intraocular pressure meter, slit lamp, synoptic machine, corneal curvature meter and other professional ophthalmic examination equipment.
Fifth, optometry time
Conventional optometry: shorter
Medical optometry: longer
Sixth, optometrists
Conventional optometry: general optometrists
Medical optometry: ophthalmologist or optometrists who are proficient in optometry and ophthalmology knowledge. Knowledge of ophthalmologists or optometrists
