Modern digital experiences are characterized by the all encompassing virtual worlds that have been the subject of much media attention. These experiences are delivered through strange looking headsets, which monitor the movement of your head in 3D to send you into a computerized environment. While there, you can do anything from killing monsters in a futuristic fantasy, to learning how to perform brain surgery on a virtual patient.
VR headsets have two tiny LCD monitors, which project at each of your eyes. This produces a stereoscopic effect that gives the user the impression of depth. Because the screens are positioned near to the user’s eyes, some experts and eye care professionals have expressed concerns about kinds of eye conditions that might develop, if users engage in these intense ocular activities for lengthy time periods.
What Issues Are Potentially Linked To VR Headsets?
The issues linked to wearing VR headsets arise from a couple of things, namely: vergence accommodation conflicts and vestibulo ocular reflex. Vergence is a term that describes the movement of the eye’s pupils during focusing that stops us from experiencing double vision. The pupils move away or toward one another, based on whether what we are looking at is nearer or further away. Accommodation is a process where the eye adjusts its’ optical power to sustain a clear view of a moving object. To do this, the lens inside the eye becomes thicker or flatter.
If a VR headset is poorly designed, what the user witnesses will not change smoothly when the user moves their head in sideways direction. This can lead to several undesirable symptoms, such as disorientation and nausea – otherwise known as virtual reality sickness. These symptoms might appear temporarily, once the headset is taken off. Activities like driving a vehicle should be avoided, until these symptoms vanish. However, there is no evidence of any long lasting change to the neurological system.
Humans have developed for these processes to work together. In daily life, you need to be able to see single images clearly. However, while you have a VR headset on, these processes are interrupted. Your eyes might converge close to the screen to look at a simulated image there, however to see that image clearly the eyes have to concentrate on the screen. This causes the undesirable symptoms in some users.
Do They Actually Strengthen The Eyes?
Over the long run though, these headsets are likely to improve the vision of users. Using these headsets has a similar effect on the eyes that lifting weights has on muscles. VR headsets strengthen the eyes, because this is precisely what is done to strengthen the eyes of patients with related conditions. Orthoptics, which is a treatment for sight problems like lazy eyes, movement disorders and squinting, improves the vision of sufferers with vergence accommodation conflicts.
Because the majority of early VR headset environments will be centered on video games, both console and mobile based, children could be potentially most at risk. The market is packed with young people — roughly twenty-six percent of gamers are below the age of eighteen – and tracking, depth perception and focus is still developing in these people. This might mean that children could develop nearsightedness, or myopia, and eye strain. A simple way to counteract this ocular stress is to get your child’s sight tested prior to starting school, encourage twenty second screen breaks every twenty minutes, and make it compulsory for them to take longer screen breaks where they carry out physical activity.
Akthough VR headsets were invent in the sixties, they did not previously experience widespread use, because the old headsets were typically too cumbersome to be worn for long periods. Also, technological restrictions like often caused nausea in wearers. With modern technology though, more responsive, lighter headsets have been created, which are ideal for the mass market.
Many of these headsets have warnings that people under thirteen should not use them, and to avoid further use if the user experiences symptoms such as motion sickness, involuntary movements, eye strain, seizures or twitching. Although these effects are normally temporary, it is not unclear whether VR headsets might cause long term problems to a person’s sight, especially with repeated use.
How Does A VR Headset Affect Your Eyesight? – Final Thoughts
Most of the time, casual users of these devices should not experience any problems. However, until the longer term effects have been properly researched, people should not use these devices too heavily. Also if they encounter eyestrain or headaches, they should stop using them immediately and seek advice from an eye specialist.

This device can be used for a variety of different tasks around your house. Anything from controlling your lights, thermostat, door locks and other things. Take a look below for step by step instructions on setting these types of things up.
Since all commands are simply spoken, once it is all set up and a quick instruction is done, it is very easy for seniors to use and get a lot of benefits from what it can do. Being able to control things around the home without getting up, monitor things around the home with devices like Smartthings, create grocery lists, etc. While, it does take some getting used to, it is a great way to help an elderly person around the house.
Setting it up in the bathroom is a great way to kind of multi-task while you are getting ready to go out or go to work. While you are getting yourself ready, you can ask it things like the outside temperature, play music, etc. It’s not a must have in the bathroom but can be a fun distraction while you are getting yourself ready to go out.
There are a number of different reasons to want to use this in your car. If your car has an internet connection, you can get local news while driving with hands-free vocal commands or even traffic reports. You can also ask it for specific music to play. If your car has an external audio jack, you can connect it to your car’s stereo system as well. If you have it set up with a garage door device, you can tell it to open your garage when you pull up to the driveway.
You can set an alarm for any certain time by simply asking it to set an alarm – “Alexa, set alarm for 8am tomorrow”. Imagine never missing another meeting or sleeping in in the morning. I can’t say how many times my bedside clock radio has failed me and caused me to be late for work. I think that this is an excellent way to remedy this type of problem.
At anytime, you can just ask Alexa for many different types of local information like the current temperature, traffic, local news, etc. This is perfect for people that have internet access in their cars (and new ones are starting to include this). A great way to get traffic information ahead of time and keep up to date on other local things. I love this aspect of it because it keeps me informed.
The Echo Dot can maintain a grocery list very easily. Are you in your kitchen and just used up the last of the milk? Just say “Alexa, add milk to the grocery list”! There are many times that I am at the grocery store, get everything I need and realize when I get home that I forgot something or forgot to write it down on my list. This way, you just say it and it’s there!
Standard cameras capture one scene and call it a day. These new ones have to capture everything that’s in front, at the back, on the sides, and so on. The resolution simply has to be high or else the resulting image will be too blurry to be useful. If you want to capture every detail, then go for the highest resolution that you can afford. Full HD or 1080p is considered too low for this kind of application. Go for a model that is capable of 15MP image resolution and 4K video resolution at the very least.
Due to the buzz surrounding 360 cameras, a lot of companies are jumping on the bandwagon. Some have come out with devices that are advertised as such but ultimately fail to deliver. For instance, they may be able to capture successive images across the horizontal plane, essentially providing a panoramic view. Yet they are not able to capture the scenes above and below them. These are not true 360-cameras because of these blind spots. Look for a model with a full field of view if you are aiming for total immersion.
As with any camera, then lens will be crucial in determining the output. The general rule is that more lenses translate to better results. This usually holds true in practice so pay attention to this when browsing the specification sheets. Of course, there are exceptions to the rule. There are devices that are able to deliver excellent images despite having only two lenses at their disposal. Quality matters just as much as quantity.
Be sure to get a model that can handle your typical usage scenarios. For instance, you might be getting one to create a 3D video of a museum for virtual tourists. The device will likely stay indoors for most of the shoots so the outer shell will not face much of a challenge save for the occasional drops. It will be different if you plan to take it on your outdoor adventures. Then it will have to be waterproof, windproof, and dustproof for a start. The shell should be impact-resistant. See if it has accessories that can give more protection.
Creating 360-degree images are videos take a lot of resources, including power. Think about the length of your shoots and find cameras that can handle the load, unless you’re fine with switching batteries in the middle of the proceedings. To give you some idea, there are models that can deliver 30 minutes of recording time and others that can last for 2hrs or more.
Finally, do check out the reviews and view their outputs for better evaluation. The hardware specs are important but so is the stitching software used to deliver the final images. Remember that the lenses still capture frame by frame in quick succession. All of these are then stitched together to create a more realistic representation of a scene. Some cameras are able to do this better than others.
It’s not hard to see why. This router definitely makes an impression right out of the box with its strong gamer aesthetic. The box resembles the powerful laptops in the Asus ROG line with its black angular cuts, vents, and trims. There are several indicator lights on top to easily check the status of different features. Four large antennas jut out from the back and the sides with hollow red trims that further enhance its gaming cred while enhancing coverage and stability. This device is capable of multi-use MIMO. On the front is a convenient Wi-Fi kill switch.
The fastest router has two USB ports that can perform similar tasks. The only difference is that one uses the 2.0 standard while the other uses the 3.0 standard so the latter will be much faster. Users can connect a storage device to any of these ports and enjoy media streaming anywhere around the house. It will not be as fast as a dedicated NAS but performance is excellent nonetheless. Another option is to attach a printer here so that it can be shared by the family. If you have a 3G or 4G stick, then you can plug it into the USB ports to serve as backup in case the primary connection fails.
There are 8 gigabit LAN ports at the back which should be more than enough for any home. This is twice the usual number of gigabit ports offered by competing products. Go ahead and plug in all of your compatible devices for various high bandwidth tasks. For instance, you can connect smart televisions and media players for crystal clear home theater entertainment during family night. Add in your set top box, your gaming consoles, your NAS devices, and more since there are plenty of ports to go around. Enjoy 4K video quality through this powerful hub. Note that you can use two of these LAN ports for link aggregation to achieve even faster speeds.
