Abstract: The present application relates to an ophthalmic lens and frame eyeglasses comprising the lens. The ophthalmic lens includes a central portion, multiple first refractive regions, and multiple second refractive regions. The multiple first refractive regions are arranged in a first zone surrounding the central portion, while the multiple second refractive regions are arranged in a second zone farther away from the central portion compared to the first zone. The central portion has a prescription power based on the human eye, and the first and second refractive regions have different powers than the prescription power. Furthermore, the total area ratio of the multiple first refractive regions to the area of the first zone is greater than the total area ratio of the multiple second refractive regions to the area of the second zone. As a result, the present application allows for more effective management and control of myopia progression.

Abstract: Some embodiments provide a centralized overlay-network cloud gateway and a set of centralized services in a transit virtual cloud network (VCN) connected to multiple other compute VCNs hosting compute nodes (VMs, containers, etc.) that are part of (belong to) the overlay network. The centralized overlay-network cloud gateway provides connectivity between compute nodes of the overlay network (e.g., a logical network spanning multiple VCNs) and compute nodes in external networks. Some embodiments use the centralized overlay-network cloud gateway to provide transitive routing (e.g., routing through a transit VCN) in the absence of direct peering between source and destination VCNs. The overlay network, of some embodiments, uses the same subnetting and default gateway address for each compute node as the cloud provider network provided by the virtual private cloud provider.
