Matters needing attention!!!!!!!
Multifocal lenses are designed according to the physiological characteristics of the individual eyeballs. For the wearer, a short adaptation period is required, which lasts about a week.
During the adaptation period of wearing multifocal glasses, you will feel dizzy because of discomfort. Don't force your eyes to get used to the lenses. You need to pass the adaptation period smoothly through some practice.
By gazing at the near, middle, and far vision targets, you can experience the full range of vision. Look at the clear place in the distance and experience the change in the sharpness of the distance vision when moving the mandible vertically; look at the clear place of the vision card and feel the change of vision when moving horizontally or the near vision card; look at the clear place of the near vision card, the vision card moves outward Increase the reading distance, experience the changes in vision when moving the position or the eye chart horizontally, and understand that the vision becomes clear by adjusting the position of the head and the position of the vision card. In addition, the wearer must be aware of the need to adapt to the surrounding deformed astigmatism area, and long-term wearing can speed up the process of adaptation.
