The multifocal structure has a first focal distance and a second focal distance of the one or more possible focal distances. The multifocal structure includes one or more optical components positioned in series such that light from an electronic display is received and passes through each of the one or more optical components at least once before being output from the multifocal structure. The one or more optical components includes a switchable half waveplate (SHWP). The SHWP has a first state that causes the multifocal structure to output image light at the first focal distance, and a second state that causes the multifocal structure to output the image light at the first focal distance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multifocal system with polarizing elements","description":"A head-mounted display (HMD) includes a multifocal block having one or more possible focal distances and includes a multifocal structure.
