The weight of the smart glasses changes according to the manufacturer and the model, for example the weight of the Epson Moverio varies between 69 gr and 290 gr, the weight of the Vuzix between 60 gr and 140 gr and finally the Realwear between 380 gr and the 430 gr.
These work tools are mini computers, they are wearable devices that are placed on the head, which is why they must be comfortable for the wearer.
From this ranking, you can see that the lightest are the Epson BT-300, the BT-350, the BT-35E.
These devices are the most elegant glasses and suitable for less demanding work environments. Another very interesting device is the latest Vuzix model, the M400, which came on the market only in September 2019, and guarantees excellent performance at just 68 gr.
Among the less light models that have been designed to be used with the protective helmet, we can find the Epson BT-2000 and BT-2200 that weight about 290 grams, and finally the Realwear HMT-1 and HMT-1Z1 with their respective weight of 380 gr and 430 gr, real “wearable” computers, perfect for more difficult environments where it is important to be resistant and ready for any context.
