We are going to compare computer glasses versus blue light glasses and which one is better at relieving digital eye strain. Let's take a look.
I'll show about the eyes vision knowledge and find the best vision product here. Today we can 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.
First of all, what are computer glasses? Well, 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. 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 is. Computer glasses are more dedicated for a further away distance, about 24 inches or 60 centimeters, that's about perfect for most people's computer screens. 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 as magazines, newspapers or perhaps your cell phone. 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. 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.
Now let's talk a little bit about blue light glasses. There are many different types of blue light glasses out there. Blue light glasses are essentially just glasses with either some type of reflector on the front and anti reflective to bounce blue light away or they're more filtered lenses. 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 and published studies on blue light has 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 no 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.
If you want the best pair you can get talk to your eye clinic. However if you're somebody who does not require prescription glasses or perhaps you wear contact lenses most of the time, then perhaps you can look at blue light glasses.
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 as we all 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 computer glasses. 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 0.5 often helps those individuals. It's just enough power in the lenses to see that things are magnified, we're leaving that eye strain without going too far and giving too much power and causing eye strain.
