The DIMS spectacle lens with multiple "micro-lens segments" projects myopic defocus and provides clear vision for the wearer simultaneously. It can slow down myopia progression in children by 60%, and 20% of the test subjects experienced no increase in myopia.

DIMS lens incorporated multiple segments with myopic defocus of +3.50 D. Refractive error (cycloplegic autorefraction) and axial length were measured at 6month intervals. Results 160 children completed the study, n=79 in the DIMS group and n=81 in the SV group.

Researchers found that even with more rapid myopia progression during the pandemic lockdown measures, the DIMS lens was associated with a 46 per cent lower degree of myopia progression in comparison with conventional single vision lens (SVL).

Aims: To determine myopia progression in children who continued to wear the defocus incorporated multiple segments (DIMS) lenses or switched from single vision (SV) to DIMS lenses for a 1-year period following a 2-year myopia control trial. Methods: 128 children participated in this study.

Date: 03 Oct 2020. The Defocused Incorporated Multi-Segment (DIMS) lens developed by the School of Optometry, PolyU, in collaboration with Hoya Vision Care, has been awarded the 2020 SILMO d’Or Award (Vision). SILMO is one of the world’s top optical fair and is known for its focus in style, technology and medical developments.

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。

The DISC lens is now licensed to a local company in Hong Kong and available as a daily disposal contact lens. Prof Chi-ho To and Prof Carly Lam, together with the Hoya Corporation, designed a novel spectacle lens called a Defocused Incorporated Multi-Segment (DIMS) lens, which incorporated myopic defocus into a conventional visual correction lens.
