DIMS 眼鏡鏡片的設計與DISC隱形眼鏡相同,同樣利用眼睛的自然回饋機制 —「正視化現象」,以減慢近視加深的速度。 DIMS 鏡片中間為一個用來矯正屈光不正(即近視和散光的「中心光學區」,圍繞中心區伸延至鏡片)周邊的則為「多區持續近視離焦」部份。 當佩戴者觀看不同距離的景物時,DIMS眼鏡片可同時提供清晰視野及近視離焦,以矯正視力。 過程中,鏡片利用上述的「正視化現象」機制,令眼球生長至一個適當的長度,影像可以正常地聚焦到視網膜上。 林教授及杜教授早前進行一個為期兩年的隨機雙盲臨床實驗,邀請160 名華裔兒童參與。 當中79位被編配至治療組,獲安排使用DIMS 眼鏡鏡片;另外81位則為對照組,被安排使用普通單焦鏡片。
