Hello and welcome to the TranslatorsCafe.com
Channel!

In this video I am going to explain how to
determine the optical power of your new eyeglasses

Do you know that you can determine the optical
power (diopters) of your next pair of prescription

bifocal or progressive eyeglasses by yourself?

— By using inexpensive glasses from a drugstore
and several trial lenses.

Because an ophthalmologist to whom you pay
your hard-earned $100 or £100 for a visit

has only about 10 to 15 minutes to help you
and that's simply not enough time.

By the way, I do it not only for yourself
(I am a presbyope), but also for my wife,

She's been wearing glasses for about 30
years and all this time she was could not

Only after I tested the lenses for her and
ordered her a new pair of glasses, she began

to recognize the birds from large distances
not only by their voice, but by their appearance.

Before that, like many short-sighted people,
she simply believed that it wasn't possible

Now, wearing the correct pair of glasses she
can see again like a ten-year-old kid and

during our daily 10-kilometer walks she constantly
shows me all kinds of hawks, woodpeckers,

cardinals, blue jays, finches, and other large
and small birds.

Watch this video, and you will learn how you
can help yourself to improve your vision!

I made this video for people like me, who
are in their forties, fifties of sixties.

As most people after their mid-forties, I
started experiencing presbyopia at about age

I had to hold books and magazines farther
and farther away from my eyes to be able to

I had to move away from the computer monitor.

At the same time, I could see things that
were far away just fine.

If you are younger, you can continue watching
just to be prepared for the future.

These problems will appear anyway and you
cannot avoid them, like you cannot avoid gray

I did not start wearing glasses until I realized
that I couln't work without mistakes anymore.

I worked as an English-Russian translator
and started wearing glasses at work only after

I made a scandalous mistake on the first page
of my translation and the client who understood

English well enough noticed it and kicked
up a big fuss.

I tried several over-the-counter glasses,
found most suitable for my work and then went

to the ophthalmologist to get a better pair
of glasses.

I remember how hard it was for me to persuade
her to prescribe me glasses that I needed.

I needed +2 to view at the monitor and paper
original simultaneously and she wanted to

prescribe me +1, which I knew and checked
was not suitable for my daily work in front

Now I know for sure that if you are well prepared,
if you did your homework, then most probably

you will know about your problem more than
your doctor does.

I am not talking about prescription or give
medical advice here — I am not a doctor.

In this video I will talk only about eyeglasses
with spherical lenses.

We will not discuss astigmatism here simply
because I don't have it and don't have

Remember that if you are past sixty, regular
eye exams are the only way to catch diseases

like glaucoma that develops slowly over time
without any pain.

Though the name presbyopia looks like a disease
and it is even called a disorder in various

Presbyopia is the gradual decline of eyes'
ability to focus on close objects causing

those objects to appear out of focus due to
hardening of the crystalline lens of the eye

The ability to focus on nearby objects declines
throughout person's life.

Small children can accommodate to 20 or even
more diopters (that is from +20 to 0 diopters

A young adult can have the amplitude of accommodation
of only 10 diopters (from +10 to 0 or from

Senior persons at age 60 and over have the
ability to view clearly only from one or two

meters to infinity or only 1 or even 0.5 diopter.

If you are past age 60 and you want to feel
that your vision is still like that of a 10-year

old kid, you will need different pairs of
eyeglasses depending on whether you are sitting

in front of a computer monitor, driving down
a highway, replacing a battery in your watch

or reading a book on a tablet, or do all the
above in different lighting conditions.

It is impossible to use a single pair of eyeglasses
for every activity.

Example of activities at your home or workplace.

Working in front of the computer monitor and
paper document reading.

When you are working in front of a monitor,
you have to remain focused on the screen and

often change focus to look at your keyboard,
you smartphone or paper documents printed

Properly selected computer glasses should
provide the best possible focus of the image

on the screen, which is usually positioned
50 to 64 cm (20 to 26 inches) from user's

eyes as well as of other things surrounding
the user (books, documents, your keyboard

or smartphone), on which the user usually
look at much less distances (usually 25 cm

For persons past age 45 the best choice is
either bifocals (less expensive) or progressive

(more expensive) with diopter values selected
for distances stated above.

I will later explain how you can select yourself
the best possible optical power of your new

If only close objects are blurry and far objects
appear normal, then you need simple reading

If, however, far objects are also blurry,
then for this kind of activity you will need

bifocals or progressives to view very distant
objects (at infinity) as well as your smartphone

or other objects at about 20 cm (8 inches)
from your eyes.

Polarized magnetic clip-on filters are preferred
for glasses used for this kind of activity

— it is more convenient and much less expensive
than photochromic lenses, which are optical

lenses that very slowly darken when exposed
to UV radiation.

Good vision acuity and wide visual field are
crucial for safe driving, therefore don't

rely on someone else — check your vision
yourself and order appropriate glasses.

Remember that photochromic (transition) lenses
will not work in your car because they are

activated by UV exposure and your windshield
and closed side windows actually block almost

Progressive lenses have reduced
visual field and therefore bifocals are much

Progressives are unsafe for driving because
of reduced clear vision field.
