[0017] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0018] The present utility model is introduced in detail in conjunction with the attached drawings.

[0019] When implemented specifically, the present utility model provides a lens - type eye - protection lamp and a study desk, including a lamp housing 1. The lamp housing 1 includes a lamp - housing light - eaves plate 101 and two groups of side end - covers, an upper light - outlet formed in the upper part of the lamp - housing light - eaves plate 101 and a lower light - outlet formed in the lower part of the lamp - housing light - eaves plate 101. The upper lamp strip 2 and the lower lamp strip 3 are detachably connected to the lamp - housing light - eaves plate 101. An upper lens body 4 is provided at the upper light - outlet of the lamp - housing light - eaves plate 101. A lower lens body 5 made of a transparent material is detachably connected to the lower light - outlet of the lamp - housing light - eaves plate 101 for evenly projecting the light of the lower lamp strip 3. At the top edge of the lower lens body 5, a first engaging part 501 and a second engaging part 502 are provided, and a third engaging part 503 is provided near its bottom edge. The lower lens body 5 is arranged in an arc - shaped structure, and its thickness increases sequentially from the inside to the outside. A plurality of evenly - distributed arc - shaped protrusions 504 are provided on the inner surface of the lower lens body 5.
