During use, the primary mirror sheet is selected low number of degrees concave lens for use, and sub-eyeglass is selected the concave lens of certain number of degrees, and sub-mirror holder can be in two positions: or superimposed with the main glasses holder lens frame, or on turn over certain angle and in this position self-locking.Sub-mirror holder and main glasses holder lens frame are superimposed when seeing thing far away, after primary mirror sheet, the addition of the sub-eyeglass number of degrees for being fit to the number of degrees of long sight; Turn on the bundle mirror holder when seeing nearly thing, use the primary mirror sheet of the low number of degrees separately.
The utility model has following advantage:
1, sees and far see the whole visuals field that to use eyeglass when near, use comfortablely, be particularly useful for seeing the user of big nearly thing such as engineering drawing.Its comfort level is better than two light formulas and gradual-change multi-focus formula eyeglass.
2, can and not have the lower frame mirror holder with the little eyeglass of prolate shape, so the gross weight after primary mirror and the sub-mirror addition is generally also less than gradual-change multi-focus formula or two light formula glasses.
3, processing technology is simple, low price.When the user needs the adjustment number of degrees along with the age increase, can only change the primary mirror sheet.Because the number of degrees absolute value that the primary mirror sheet need be adjusted is less, sub-eyeglass generally need not be changed.
4, sub-eyeglass generally is in superimposed position during outdoor activity, and its aesthetics is as broad as long with general glasses.
5, if the patient sees need near-sighted glasses when far away and see and to hang down the number of degrees presbyopic glasses when near that the utility model is suitable equally.
