The single word optical has great global search statistics, and this domain name (with the .gdn global domain name extension) could be used a startup company in one of the optical fields, a company that provides eye glasses, or a reference site on the science of optical devices. It is ideally suited to use with subdomains and as such could have a web address like medical.optical.gdn or ACME.optical.gdn (e.g. for a company Acme Optical). We are offering it at a small fraction of its third party estimates of worth (Estibot $1300, GoValue $1151 - check current estimates if this information is important to you). The domain name is already registered until Jan. 22, 2019, and renews at reasonable .gdn rates.
