The target search platform and the method based on multi-parameter acquisition are convenient to control and have wide application. The handheld terminal can be carried to select the spectacle frames with different sizes for the spectacle matching users with different face shapes, so that the blindness of selecting the spectacle frames by the users is overcome.
Detailed Description
The following describes the embodiments of the multi-parameter acquisition-based target search platform and method of the present invention in detail.
The glasses preparation is divided into: full frame, half frame, frameless, eyebrow frame, and combo frame. Try to avoid wearing the picture frame which is too similar to the shape of the face of a user so as to avoid excessively strengthening the lines of the face. The frameless frame easily fits any skin tone, facial shape.
The general facial form is divided into: round, goose egg-shaped, square, inverted triangle, etc. The shape of the face determines the shape of the frame. Carefully observe your face to see where is higher and where is flatter. When selecting the frame, you should go back to your way depending on the face. For example, a person with a very round face may not be able to wear round eyeglasses properly. However, you do not try on the various styles of frames. Perhaps you can find a surprise for you.
The frame is selected taking into account the interaction with the lens: the larger the frame size, the larger the effective diameter of the frame, the larger the minimum lens blank required, and the thicker and heavier the lens after edge cutting. Therefore, high lenses and aspheric lenses require small, symmetrical, circular or square frames, which are not suitable for frames with an excessively long meridian. The progressive mirror requires a frame of appropriate height, i.e., a vertical distance from the center of the pupil to the bottom of the internal groove in the rim of the mirror of at least 22 mm.
For single vision lenses, particularly aspheric lenses, the frame is selected so that the visual axis passes above the central horizontal line when the wearer is looking flat. If the distance between the pass point and the central horizontal line is maintained in a relationship of 1 mm to 2 degrees with respect to the anteversion angle, the optical center should be located on the central horizontal line when worn.
For a highly astigmatic lens, the direction of the meridian where the power is highest needs to be taken into account. Such as + 6.00/-4.00 x 180 lenses, require the selection of a relatively narrow, relatively tall frame, which is not too thick at the top and bottom edges. While the + 6.00/-4.00 x 90 lenses are selected to be wider and shallower frames.
At present, the mode of selecting the spectacle frame by a user is to visually observe and select various spectacle frames arranged in a merchant, obviously, the mode of visually observing and selecting is too rough and has certain blindness, so that the user is difficult to be helped to select the spectacle frame with the proper face, and once the spectacle frame is provided with lenses, the spectacle frame is replaced, so that a great deal of energy and material resources of the user are consumed.
In order to overcome the defects, the invention builds the target search platform and the method based on multi-parameter acquisition, and can effectively solve the corresponding technical problems.
