Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic detection, in particular to an ophthalmic detection device. Background Art

[0002] Ophthalmological examination is a very common routine health examination. The main part of the examination is the eyes. There are many types of examination items, including vision examination and color recognition examination. During the examination, the doctor needs to use a lot of examination tools and means. These examination tools or equipment are classified into different categories, each with its own examination direction and range. The ophthalmic information obtained by these testing tools is of great reference value and significance. Today, with the increasing application of electronic products, people's lives are increasingly inseparable from various electronic products. Long-term use of electronic products will greatly affect our eyesight, so it is necessary to accurately measure the patient's vision.

[0003] The traditional measurement method is that the patient stands at a certain distance from the eye chart and tests the patient's vision by looking at the eye chart. In order to ensure the accuracy of the examination during the examination, different eye charts need to be used when testing vision at different distances. After changing the examination distance, the staff needs to manually replace it, and the distance needs to be measured again when the distance is changed.
