Why do you need to wear glasses on a time traveling machine?
In recent years, the sport of flying drones (FPV drones) has rapidly emerged around the world and has become a new favorite among technology and extreme sports enthusiasts. However, many novices often wonder when they come into contact with the traversing machine: Why do they need to wear special glasses when operating the traversing machine? This article will combine the hot topics and hot content on the Internet in the past 10 days to analyze this issue in detail for you from the three dimensions of security, experience and technology.
1. The core reasons for wearing glasses on time travel machines

Wearing glasses (usually FPV glasses or a head-mounted display) is an indispensable part of the operation of the traversing machine. The main reasons are as follows:
| Reason | Description |
|---|---|
| First person perspective (FPV) | Receive drone camera footage in real time through glasses for an immersive flight experience |
| Reduce environmental disturbance | Block out external light and focus on the flight screen |
| Security protection | Some glasses have anti-glare and anti-blue light functions to protect the operator's vision |
| Precise control | High frame rate, low latency picture transmission helps to judge complex actions |
2. Correlation analysis of recent hot topics
According to the data monitoring of the entire network in the past 10 days, discussions related to time-traveling machine glasses are mainly concentrated in the following areas:
| Topic classification | heat index | Typical discussion content |
|---|---|---|
| Equipment Buying Guide | 85% | How do novices choose cost-effective FPV glasses? |
| health effects | 72% | Will wearing it for a long time cause damage to vision? |
| Technology upgrade | 68% | Visual differences between digital image transmission and analog image transmission |
| Competition rules | 55% | Standard requirements for eyewear equipment in professional competitions |
3. Technical evolution of FPV glasses
Judging from recent reports in technology media, FPV glasses technology is undergoing rapid iterations:
