Myopia Control Efficacy of Spectacle Lenses with Aspherical Lenslets: Results of a 3-year Follow-up Study.

American journal of ophthalmology-glaucoma, 2023
PURPOSE To investigate myopia control efficacy in children who continued wearing spectacle lenses with highly aspherical lenslets (HAL) or switched from spectacle lenses with slightly aspherical lenslets (SAL) and single-vision spectacle lenses (SVL) to ...

Optical characterisation of two novel myopia control spectacle lenses

Ophthalmic & physiological optics, 2023
To quantify the amount of myopic defocus, contrast modulation and other optical characteristics of two novel spectacle lenses (MiYOSMART by Hoya and Stellest by Essilor) with the inclusion of lenslets in their designs were investigated computationally ...

One-year myopia control efficacy of spectacle lenses with aspherical lenslets

British Journal of Ophthalmology, 2021
Aims To evaluate the 1-year efficacy of two new myopia control spectacle lenses with lenslets of different asphericity. Methods One hundred seventy schoolchildren aged 8–13 years with myopia of −0.75 D to −4.75 D were randomised to receive spectacle ...

Control of myopia using diffusion optics spectacle lenses: 12-month results of a randomised controlled, efficacy and safety study (CYPRESS)

British Journal of Ophthalmology, 2022
Background Mutations in the L/M cone opsin gene array cause abnormally high perceived retinal contrast and the development of myopia. Environmental factors may also lead to high visual contrast and cause myopia.

Defocus incorporated multiple segments (DIMS) spectacle lenses increase the choroidal thickness: a two-year randomized clinical trial

Eye and Vision, 2023
Background Myopia control interventions, such as defocus incorporated multiple segments (DIMS) spectacle lenses, have been adopted in school-aged children to reduce the prevalence of myopia and its complications.

The impact of spectacle correction on the well-being of children with vision impairment due to uncorrected refractive error: a systematic review

BMC Public Health, 2023
Background Despite being easily corrected with eyeglasses, over two-thirds of the world’s child population presents with vision impairment (VI) due to uncorrected refractive errors.

A Monte Carlo simulation study on the evaluation of radiation protection properties of spectacle lens materials

The European Physical Journal Plus, 2023
The eye lens has been known a radiosensitive tissue. Radiation exposure can cause opacities, cataracts and vision loss. The sensitivity of the eyes to ionizing radiation has attracted attention in the last decade.

Age-matched analysis of axial length growth in myopic children wearing defocus incorporated multiple segments spectacle lenses

British Journal of Ophthalmology, 2023
Background/aims Defocus incorporated multiple segments (DIMS) spectacle lenses are known to be able to inhibit axial length (AL) growth in myopic children compared with single vision (SV) spectacle lenses.
