in this video we are going to compare computer glasses vs blue light
glasses and which one is better at relieving digital eye strain plus stay
tuned toward the end as well show some tips on how to find the right powers for
your computer glasses let's take a look
hello and welcome this is dr. Allen here from the doctor eye health show helping me
learn all about the eyes vision and finding the best vision product so if
you're new to the channel definitely consider subscribing now 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 off 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 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 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 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 as
magazines newspapers or perhaps your cell phone the whole point of having
this magnification in the pair of to 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 ice 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 I always like to compare it
to lifting weights 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 five-pound weight instead of that 20 now let's talk a
little bit about blue light glasses now there are many different types of blue
light glasses out there in fact I've done several videos on blue light
glasses if you haven't seen those videos and I will hook those in YouTube card up
above here as well as in the video description below so if you want to
check those out you can find them easily but 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 with kind
of a yellow or amber color to them kind of similar to the ones I have here and
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 so if you're
somebody who doesn't want any prescription maybe you just don't like
the feel of it you don't like the look of it then you can always just get plain
old lenses like I have here but because 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 fact that is what's most oftenly recommended
for people who are looking for a dedicated pair of computer glasses
another thing that can get confusing is that there's also gaming glasses don't
be too thrown off by this gaming glasses are usually just computer glasses with a
blue light filter in them but oftentimes gaming glasses only come in non
prescription or plano lenses or they come in a very weak Plus plower
something like a plus a 0.25 or a plus a 0.5
zero 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 and I've got some tips to share but first go and
smash that like button for me and leave a comment below and let me know if
you're using computer glasses that are dedicated for the computer or using some
sort of no no prescription plain old blue light lenses now 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's several
things your eye doctor needs to consider not just how far away you're using a
computer screen but also the status of your eye muscles and how much those
muscles can contract and hold a 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 however if
you're somebody who does not require prescription glasses or perhaps you wear
contact lenses most of the time like I do 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 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 0 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 for people who are in their early to mid 40s usually getting
around a plus 1 reading prescription or again a computer glasses prescription is
does excellent for those needs for 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 and then ultimately around a 1.75 for anybody who's around the age of
60 again these are all approximations based on
and I 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 process if you
want more detailed layout information of the powers and the age as well as all
the different lenses and frames that I've showed off here in this video I
will hook those up in the YouTube description below for you can check
those out easily otherwise if you would like to learn more tips and tricks about
relieving eyestrain from computer vision syndrome I have a whole video on that
