Abstract
A low vision glasses array lens assembly visual system comprises a main body; a front portion of the main body is a micro display screen displaying observation image; a left side of the micro display screen is an array lens assembly preposition magnifier; the array lens assembly preposition magnifier comprises a series of minimal lens units divided into corresponding two rows and arranged on two sides of a lens basal body so as to form a series lens assembly; a focus of each small unit lens in a left lens group is matched with that of each small unit lens in a right lens group, certain angle is mutually formed between the minimal lens unit groups, so each minimal lens unit group can form a minimal magnifying lens, and field-of-view of each minimal magnifying lens is very small, so aberration can be almost zero; the minimal lenses can form the assembly being the array lens assembly preposition magnifier; people can observe the image displayed by the micro display screen through the array lens assembly preposition magnifier, so field-of-view is big, aberration is small, and image is clear; the array lens assembly preposition magnifier is small in size, light in weight, and suitable to be worn on an amblyopia patient head in a glasses mode.
Description
Technical field
The utility model relates to a kind of visual system, particularly a kind of low vision spectacles array lens group visual system.
Background technology
Existing preposition magnifier is generally comprised of one group of multi-disc lens, complex structure, bulky, be not suitable for being worn on low eyesight person's head with glasses form, and the preposition magnifier of existing single element lens generally consists of aspheric surface, but the visual field that can guarantee image quality is minimum, and aspheric surface simple lens cannot color difference eliminating.
Summary of the invention
For addressing the above problem, the purpose of this utility model is that the low vision spectacles for ease of wearing provides a kind of and can guarantee large view field imaging quality little, the lightweight visual system of volume again.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of low vision spectacles visual system, comprise main body 1, it is characterized in that: described main body 1 is anterior is micro-display screen 2, described micro-display screen 2 right sides are the preposition magnifier 3 of array lens group, preposition magnifier 3 left-hand face of described array lens are provided with junior unit lens group 4, preposition magnifier 3 right lateral surface of described array lens are provided with junior unit lens group 5, the focus of each junior unit lens in the lens group 4 of left side overlaps with the focus of each junior unit lens in right side lens group 5, form lens combination, and each group is mutually certain angle between lens combination and is regular array-like and arranges.
Technique scheme has following beneficial effect: the preposition magnifier of array lens group is divided into two corresponding rows by a series of micro lens unit and is distributed in lens matrix both sides and forms a series of lens combination, the focus of each junior unit lens in the lens group of left side overlaps with the focus of each junior unit lens in the lens group of right side, and be mutually certain angle between each group micro lens unit, each group micro lens unit group has just become one group of small enlarging lens like this, thus again because each to organize the very little aberration in visual field of small enlarging lens almost nil.And the set being formed by these micro lens camera lenses has just become our preposition magnifier of array lens group, and human eye watches by the preposition magnifier of array lens group the image that micro-display screen shows, not only visual field is large, aberration is minimum, and because the preposition magnifier volume of array lens group is little, lightweight, be applicable to being worn on amblyopia patient's head with glasses form
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of instructions, below with embodiment of the present utility model and coordinate accompanying drawing to be elaborated to this patent.
Accompanying drawing explanation
Fig. 1 is use schematic diagram of the present utility model.
Fig. 2 is the local enlarged diagram of the preposition magnifier of array lens group.
Embodiment
As depicted in figs. 1 and 2, a kind of low vision spectacles visual system, comprise main body 1, it is characterized in that: described main body 1 is anterior is micro-display screen 2, described micro-display screen 2 right sides are the preposition magnifier 3 of array lens group, , preposition magnifier 3 left-hand face of described array lens are provided with junior unit lens group 4, preposition magnifier 3 right lateral surface of described array lens are provided with junior unit lens group 5, the focus of each junior unit lens in the lens group 4 of left side overlaps with the focus of each junior unit lens in right side lens group 5, form lens combination, and each group is mutually certain angle between lens combination and is regular array-like and arranges.
Below in conjunction with embodiment, the present invention is further detailed explanation: adopted the preposition magnifier of array lens group, the preposition magnifier of array lens group is divided into two corresponding rows by a series of micro lens unit and is distributed in lens matrix both sides and forms a series of lens combination, the focus of each junior unit lens in the lens group of left side overlaps with the focus of each junior unit lens in the lens group of right side, and be mutually certain angle between each group micro lens unit, each group micro lens unit group has just become one group of small enlarging lens like this, again because each thereby to organize the very little aberration in visual field of small enlarging lens almost nil.And the set being formed by these micro lens camera lenses has just become our preposition magnifier of array lens group, and human eye watches by the preposition magnifier of array lens group the image that micro-display screen shows, not only visual field is large, aberration is minimum, clear picture, and because the preposition magnifier volume of array lens group is little, lightweight, be applicable to being worn on amblyopia patient's head with glasses form
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
