Description

Technical Field

[0001] The utility model relates to the technical field of study tables, in particular to a study table associated with myopia prevention and control. Background Art

[0002] The study table is a new, scientific, humane and practical learning aid suitable for children and teenagers aged 3-18. It can be adjusted up and down and the tabletop can be tilted. The study table is an indispensable learning tool for primary and secondary school students. With the trend of intelligent daily necessities, the study table is also developing in the direction of intelligence, and its functions are gradually becoming diversified.

[0003] However, when using the existing study table for reading books, it is not convenient to reasonably control the distance between the book reading stand and the user, and it is easy to get close to the book inadvertently, causing visual fatigue and myopia due to long-term reading. Then, when using the study table, the distance between the user and the study table cannot be supported and pushed, which can easily cause long-term crouching, neck fatigue, non-standard distance between eyes and books, and myopia.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a study table related to myopia prevention and control is proposed. Utility Model Content
