    The fitting methods and precautions of progressive tablets for the elderly are as follows:

    1. Optometry of progressive multifocal lenses.

    The optometry process of progressive multifocal is not much different from the optometry of ordinary lenses, and it is also divided into 3 stages

    1) Correction of remote diopters.

    Initial Phase: Examination General examination of the eye Unaided visual acuity, refractive and corrected visual acuity examination of the old glasses Computerized refraction Imaging examination.

    Fine-tuning phase: two-color test, astigmatism table and cross cylindrography.

    Terminal Stage: Examination of the Dominant Eye Binocular balance and other visual function tests.

    2) Near-diopter examination.

    Cross-lattice method:

    The cross-cylindrical mirror placed in front of the eye has a negative axis of 900 and a positive axis of 1800 until the horizontal and vertical lines are as clear.

    Empirical method: (age -30).

    For teenagers, ADD is generally +.

    2. Selection of frames.

    For the selection of frames, first of all, it is required that the center point of the pupil to the inner edge of the lower frame of the frame is generally not less than 22mm, for the standard channel 18mm or 19mm frame height should be 34mm, the short channel or 14mm frame height should be 30mm, and avoid choosing the nose side of the large bevel of the frame, because it is easy to "cut off" the reading area, and try not to choose the frameless frame, because it is easy to loosen, so that various parameters change. Also, be sure to choose a frame that has nose pads that can be adjusted.

    3. Measurement of interpupillary distance.

    For the interpupillary distance, we need to measure the right and left interpupillary distance of each eye separately (because the bridge of the nose of many people is not necessarily located in the center of both eyes), and the interpupillary distance should be accurate, and the measurement methods are: pupillary distance meter, interpupillary distance ruler and marked with a sample marking method and then measured with a progressive lens measurement card.

    4. Measurement of pupil height.

    Pupil height is the vertical distance from the center point of the pupil to the inner edge of the lower frame of the frame.

    The symptoms of inability to adapt are generally too narrow in the reading area, blurred vision near and far, dizziness, shaky feeling, distorted vision, and the need to turn the eyes or tilt the head to see objects. For these discomforts, we have to ask the customer about the original diopter, original glasses and eye needs.

    We mainly need to consider and analyze the diopter of the lens we wear, the parameters of the glasses and the frame condition.

    In the past two years, many optical stores have been promoting progressive multifocal lenses, and the product range has also increased. With the increasing aging of China's population, a large number of elderly customers have a growing demand for progressive lenses, but because many optical stores have not conducted systematic training for practitioners on progressive lens fitting, and many fitting personnel lack practical experience, there are many customer complaints.

    Answer 1, the refraction of progressive multifocal lensesThe refraction process of progressive multifocal lenses is not much different from the refraction of ordinary lenses, and it is also divided into 3 stages, the following is a brief description of the process: 1) The initial stage of correction of remote diopter: Consultation General eye examination Naked-eye vision, examination of diopter and corrected visual acuity of old lenses Computerized refraction Examination.

    Fine-tuning phase: two-color test, astigmatism table and cross cylindrography. Termination Phase:

    Examination of the main eye Balance and other visual function tests of the eyes.

    Surgery** is a surgical method to adjust the strength of the external eye muscle and the position of the attachment point to normalize the eye position. Most congenital esotropia and strabismus require surgery**, and non-accommodative and oblique strabismus usually need to be corrected by surgery.
