反轉拍功能的試鏡架的設計

        一種具有反(fan)轉(zhuan)(zhuan)(zhuan)拍(pai)功能的試鏡(jing)(jing)(jing)(jing)(jing)架,設計科學合(he)(he)理,結構簡(jian)單,使(shi)用(yong)時(shi)(shi)被檢(jian)查(cha)者頭戴本試鏡(jing)(jing)(jing)(jing)(jing)架,旋鈕彈(dan)動(dong)卡合(he)(he)機構的軸桿,通過受力(li)傳遞,驅動(dong)翻轉(zhuan)(zhuan)(zhuan)機構促使(shi)翻轉(zhuan)(zhuan)(zhuan)鏡(jing)(jing)(jing)(jing)(jing)片(pian)發生(sheng)翻轉(zhuan)(zhuan)(zhuan).且根據使(shi)用(yong)檢(jian)查(cha)或訓(xun)練(lian)需要對鏡(jing)(jing)(jing)(jing)(jing)片(pian)進(jin)行移動(dong),翻轉(zhuan)(zhuan)(zhuan)鏡(jing)(jing)(jing)(jing)(jing)片(pian)和固定鏡(jing)(jing)(jing)(jing)(jing)片(pian)利用(yong)兩球面透(tou)鏡(jing)(jing)(jing)(jing)(jing)鏡(jing)(jing)(jing)(jing)(jing)片(pian)同(tong)(tong)軸聯合(he)(he),度(du)數疊加(jia)的原理:即兩個異號球面透(tou)鏡(jing)(jing)(jing)(jing)(jing)同(tong)(tong)軸聯合(he)(he)后,形成(cheng)(cheng)一個新(xin)的球面透(tou)鏡(jing)(jing)(jing)(jing)(jing),其屈光力(li)為(wei)兩球面透(tou)鏡(jing)(jing)(jing)(jing)(jing)屈光力(li)代數和.實(shi)(shi)現(xian)反(fan)轉(zhuan)(zhuan)(zhuan)拍(pai)和試鏡(jing)(jing)(jing)(jing)(jing)架的結合(he)(he),配鏡(jing)(jing)(jing)(jing)(jing)者可以在試鏡(jing)(jing)(jing)(jing)(jing)的同(tong)(tong)時(shi)(shi)完成(cheng)(cheng)反(fan)轉(zhuan)(zhuan)(zhuan)拍(pai)的檢(jian)查(cha)和訓(xun)練(lian),更(geng)好的實(shi)(shi)現(xian)視功能檢(jian)查(cha)或訓(xun)練(lian),且檢(jian)測(ce)方便準確,實(shi)(shi)際(ji)使(shi)用(yong)效(xiao)果佳(jia)。
