The current invention is directed to a method for designing an ophthalmic lens element, the method comprising the steps of determining a wavefront aberration of an eye in a reference plane, wherein the wavefront aberration of the eye can be described by a first series of polynomials of ascending order up to a first specific order and corresponding first coefficients; determining a first vision correction of a second specific order; determining at least one specific point over an aperture of the adapted ophthalmic lens element; determining a high-order wavefront aberration in the reference plane for each specified point of the adapted ophthalmic lens element, wherein the high-order wavefront aberration can be described by a third series of polynomials of ascending order above the second specific order up to and including the first specific order and corresponding third coefficients; and determining a second vision correction of the second specific order.

The invention relates to a method for producing high-yield gamma-propalanine and an application thereof, belonging to the technical field of biotechnology medicine and food engineering. The method comprises the following steps: carrying out strain separated screening, acridine orange-ultraviolet ray mutagenesis and N<+> injection mutagenesis to obtain a high-yield gamma-propalanine LactobacillusbrevisTCCC (CGMCC No.3414) strain; optimizing a fermentation medium and fermentation conditions; coupling fermentation of the gonotokont of the strain with resting cell biotransformation of the strain to produce the gamma-propalanine; employing the membrane filtration technology, the adsorbent resin decoloration technology, the strong acid resin cation exchange technology, the ethanol recrystallization technology, the preparative chromatography technology and the energy-saving and cost-reducing technology to separate the gamma-propalanine from the fermentation fluid and the biotransformation fluid; and then carrying out purification to obtain the crystallized gamma-propalanine with the purity of 99%. The method has the advantages of cheap raw materials, low energy consumption for production, low production cost, good product security and easy realization of industrialized production. Applied to glutamic acid fermentation waste liquor for producing the gamma-propalanine, the strain has good potential for generating social and economic benefits.

The invention discloses a full-automatic eyeball training instrument. The full-automatic eyeball training instrument comprises a remote controller and an automatic swinging device; the automatic swinging device comprises a control motor, a connecting and fixing device and a small swinging ball, wherein the connecting and fixing device is connected to the lower side end of the control motor, and the small swinging ball is connected to the connecting and fixing device through a connecting wire; a base is located below the automatic swinging device, idler wheels are arranged at the lower end of the base, rest rods are located on the base, and the rest rods comprise the horizontal rest rod and the vertical rest rod; the lower end of the vertical rest rod is connected to the middle of the base, and a second power-driven telescopic regulation box is arranged on the vertical rest rod; a first power-driven telescopic regulation box is arranged on the horizontal rest rod, and the upper end of the vertical rest rod is connected to the first power-driven telescopic regulation box. The full-automatic eyeball training instrument has the advantages that the frequency of ball swinging is normalized, and the moving ability of the eyeball is improved. The invention further discloses a using method of the full-automatic eyeball training instrument.
