VRD's disadvantages

Of course, this emerging technology called Virtual retinal display does not have only advantages. First of all, since this technology is still in the development process, its cost are therefore very high and its use, limited. Also, even though the device is light and small, some improvements have to be done in order for it to be fully efficient in a workplace. Indeed, even though the device can be worn as regular glasses, if the user must also carry a 50 pound battery and processor, this makes its use a bit less interesting.


Finally, a last disadvantge is that limited brightness if VRD makes its use more difficult when used outdoor. Even though this problem is being worked on, it is seen as a current problem of the technology.




In conclusion, these disadvantages are mostly due to the fact that this technology is new and, therefore, the cost realted to it are very high. In other words, these disadvantages should be reduced or eliminated as more researches and improvments are made.
