The Safety and Efficacy of SYD-101 in Children With Myopia
Myopia, or nearsightedness, is the most common eye disorder, often affecting more than 40% of adults in Europe, Asia and the USA. Severe myopia is associated with an increased risk of developing other eye conditions such as glucoma, cataracts and retinal detachment, which may lead to blindness. Early treatment of myopia in children could help slow the condition and minimize the risk of complications later in life. This study investigates the use of SYD-101, an eye solution, in slowing-down the progression of myopia in children.

Effect of Defocus in Soft Contact Lenses on Internal Retinal Vascularization
The purpose of this study is to gain a better understanding of the retinal vascular changes that occur in response to the optical effect of a myopic defocus daily disposable soft contact lens (MDSL) in a group of healthy young myopic adults (18-35 years; myopia -1.00D to -4.00D; all genders). It will also learn about the acceptance of this visual correction modality compared to regular contact lenses. The main questions to be answered are: * To evaluate changes in retinal blood flow by visualizing retinal vascular density in the superficial and deep plexus after one week of MDSL wear. * To evaluate changes in choroidal thickness at the macular level after one week of MDSL wear. * To evaluate the visual comfort provided by this MDSL design using a questionnaire. Researchers will compare the MDSL to a daily disposable single vision soft lens (SVSL) used to correct myopia to determine if the addition of a defocus area makes a difference in the retinal response to the visual signal. Participants will be required to * Wear both MDSL and SVSL for one week each, in a random order. * Read letters to measure visual acuity * Have a deep scan of their retina with an optical coherence tomography (OCT) device * Rate the comfort and vision provided by both devices using a questionnaire.
