After launching the new version of Google Glass, Google also recently launched a dedicated accessories store for Google Glass. Google Glass users can access the accessories store via the "My Glass" dashboard or through the Google Glass help website.
The currently available products in the Google Glass accessories store include chargers, earplugs, sunglasses, prescription glasses, frames, and cases, with the $75 (approximately 460 RMB) prescription glasses already on sale.
It is understood that the dedicated Google Glass earplugs can be connected via the charging interface's micro USB port, priced at $50 (approximately 310 RMB), the charger is also priced at $50 (approximately 310 RMB), and the dedicated Google Glass case is priced at $50 (approximately 310 RMB).
Although the prices of these accessories are not particularly low, since the developer edition of Google Glass already includes sunglasses, a charger, and a case in its standard packaging, most developers using Google Glass probably won't need to spend extra money on these items.
