Computer glasses: Necessary Tips to find Right Power

In this article, we are going to compare computer glasses vs blue light glasses and which one is better at relieving digital eye strain plus some tips on how to find the right powers for your computer glasses.

Today are going to talk about computer glasses and blue light glasses and really comparing the difference in figuring out which one is better for relieving your eye strain.

 

What are Computer Glasses?

Computer Glasses

Computer glasses are a dedicated pair of glasses with magnification power to relieve eye strain while looking at a near object that is about the distance of your computer screen and yes computer glasses are very similar to reading glasses, in fact, some people even use reading glasses as computer glasses it really has to do with how far away the object you're focusing on.

 

Difference Between Computer glasses and Reading glasses?

Computer glasses are more dedicated for a further away distance of about 24 inches or 61 centimeters that's about perfect for most people's computer screens where reading glasses are more dialed in for objects up-close closer to around 40 centimeters or perhaps closer depending on where you like to hold things for reading.

In fact, we call this distance where your elbows are just barely touching your body and you're holding an object out here that's called a Hartmann distance or also known as your elbow distance which is ergonomically better for looking at things like books, magazines, newspapers or perhaps your cell phone.

 

Why it is important to maintain Hartmann/Elbow distance?

The whole point of having this magnification in the pair of dedicated computer glasses is to relieve the muscle tension inside the eye and the eye muscles outside of the eye from having to overwork and be fatigued from staring at a set distance so close for so long.

So, if you're somebody who spends a lot of time throughout your day on a digital screen up close and you're getting eye strain maybe that pinching feeling between the nose pressure on the outside of your temples or maybe headaches then getting a pair of dedicated computer glasses could help relieve that feeling.

 

According to Dr. Joseph Allen, Our eyes really aren't meant to hold our eyes at a certain distance for so long it's kind of like lifting up a 20-pound weight and trying to hold it there for as long as you can eventually, your muscles are gonna get tired and computer glasses essentially lower the weight down so maybe you're holding a 5-pound weight instead of that 20.

 

What are Blue Light glasses?

Blue light glasses are essentially just glasses with either some type of reflector on the front and antireflective coating to bounce blue light away. They're more filtered lenses with kind of yellow or amber color to the kind of similar to the ones in the image below.

 

They eliminate the harsh blue light that you get from looking at things like computer screens or any of the artificial LED light bulbs that we have in the home.

 

According to some published studies on blue light, researchers found that it does affect our melatonin production and that affects our sleep cycles and there are some studies out there and many people who will claim that blue light glasses help relieve their eye strain.

 

So many types of blue light glasses that you find out there are usually, non-prescription they are simply just filters or some type of anti-reflective coating on top of a lens.

 

Blue light blocking technology is really kind of an add-on that can be made in the lenses themselves you can even double up and you can have computer lenses that also have blue light blocking technology.

 

In fact, that is what's most often recommended for people who are looking for a dedicated pair of computer glasses.

 

What are Gaming glasses and How they are different from Computer and Blue Light glasses?

Another thing that can get confusing is that there are also gaming glasses. They are usually just computer glasses with a blue light filter in them but often times gaming glasses only come in non-prescription or Plano lenses or they come in a very weak Plus plower something like a plus  0.25 or a plus 0.50

 

Computer glasses Vs Blue Light glasses?

Till now, we got a clear idea that Computer glasses are best to be preferred for relieving eye strain and stress because these have additional opportunities to get a pair with blue light blocking technology Hence, Computer glasses can solve our all purposes.

Tips to find the right power of Computer glasses

How to Find a Good Pair of Computer glasses?

Now the real trick to finding a good pair of computer glasses and relieving digital eye strain has to do with finding the right powers of the computer glasses for you.

For most people to get the best pair of computer glasses they will get that measured out at their eye clinic by their local eye care professional because there are several things your eye doctor needs to consider not just how far away you're using a computer screen there are:

1. Status of your eye muscles.

2. How much those muscles can contract.

3. The focusing distance that's something that does change throughout our lifetime and is very personal from person to person.

So, if you want the best pair you can get talk to your eye clinic.

Tips to Find Computer glasses that work best for you without prescription

If you're somebody who does not require prescription glasses or perhaps you wear contact lenses most of the time for distance then perhaps you can look at some other options and here are some tips to figuring out those right powers a quick rule of thumb that many eye care professionals will use to calculate.

At least the initial setup for the right powers for computer glasses and reading glasses is based on somebody's age with age we lose the ability to really focus well up close. That means the older you get the more power you will need for your glasses.

1. In general, if you're under the age of 40 and have no problem seeing things up close then finding a pair of computer glasses around a plus 0.25 or a plus 0.50 often helps those individuals. It's just enough power in the lenses to see that things are magnified we relieving that eye strain without going too far.

2. Giving too much power will cause eye strain for people who are in their early to mid-40s usually getting around a plus 1 reading prescription or again a computer glasses prescription does excellent.

3. Somebody who's more age 50 and above they're typically gonna need something stronger somewhere around a 1.25 going up to a 1.50.

4. Around 1.75 for anybody who's around the age of 60.

Again these are all approximations and we do recommend if you are looking for the best pair again speak to your eye doctor again because there are so many variables in this.

 

   

Is Computer Glasses Necessary?

Computer glasses are not necessary if you are from those who do not spend a long day in front of computer screen.   It  is necessary for the second kind of people those who spend a very long time in front of a computer screen and after that they start feeling headache, difficulty in vision, some other vision problem and their doctor prescribed these computer glasses to them. These glasses are only for the safety of your eyes as we discussed earlier and it’s up to you. They do help your vision and ultimately your eye.
