[0050] See also Figure 1-Figure 6 The present invention can enable the peripheral vision to see far or feel far light at any time while reading and writing, so the effect of treating and preventing myopia is better, and it is convenient and applicable for reading and writing.

[0051] The telescope reflector can be a positive flare or a reverse flare, and its angle can be any angle as long as the reader can see or unconsciously feel the light reflected from the outer far side through the telescope reflector while reading or writing. The telescope reflector can also be a flat reflector.

[0052] The convex lens or the magnifying effect of the convex lens is mainly used to magnify or distance the viewed object, making it more convenient and labor-saving for the reader to read and write.

[0053] like Figure 2 The convex lens or lens group 11 is installed in the seat 12 and the threaded cover 13. The seat 12 is fixed to the back of the lower side of the telescope cover 4 by screws. It can also be fixed on the base 1. The lower jaw support plate and the seat are installed on the upper part of the bent rod of the screw deflection lifting adjustment mechanism, and the lower part of the bent rod is locked by screws in the bar hole on the upper part of the lifting adjustment mechanism (as shown in the figure).
