Pupil distance adjusting equipment on glasses reach

Technical Field

The utility model relates to a glasses technical field especially relates to a interpupillary distance adjusting equipment on glasses reach.

Background

Spectacles are known to be lens or plano lenses inserted in a frame and worn in front of the eyes in use for improving vision, protecting the eyes or for decorative purposes. The lenses can correct a variety of vision problems including myopia, hyperopia, astigmatism, presbyopia or strabismus, amblyopia, and the like. With the increase of age, particularly after the age of 40, with the gradual fiber hardening of crystalline lens of human eyes, ciliary muscles are gradually paralyzed, so that the human eyes cannot effectively adjust the shapes of eyeballs, and only by adjusting the distance between the eyes and an object to be seen, the human eyes must move far to see clearly when seeing a near object, the eye state is called presbyopia, and the presbyopia needs to wear presbyopic glasses to supplement the eyesight to see the near clearly again when using the eyesight at the original customary distance. However, the existing glasses are improved in a portable way, for example, adjustment is made in the aspects of folding or narrowing, so that each pair of glasses can only be suitable for a specific individual to wear, but the existing finished presbyopic glasses circulated in the market are manufactured when the lenses and the interpupillary distance are delivered from a factory and cannot be adjusted, and the interpupillary distance of each individual is different, so that when different people wear the glasses, the near-eye position set is excessive or insufficient due to inaccurate interpupillary distance, and discomfort is caused due to the image fusion problem.

In view of the foregoing, there is a need for improvement in the shortcomings of the prior art presbyopic glasses.

SUMMERY OF THE UTILITY MODEL
