За годы жизни на чужбине в Штатах мы уж привыкли к таинственному выражению twenty–twenty. Как и к тому, что редкий носитель близорукости в курсе, что оно означает. Если опросить случайных граждан, то 76% скажут, что это «когда видишь все». Пусть так, но 20 на 20-то тут при чем?

Доктор, должен признаться, что сам являюсь таким же невеждой, как все. Из СССР я контрабандой вывез какие-то древние представления, и до сих пор могу продекламировать незабвенные строчки: ШБ, МНК. Ну а местная таблица вроде ничем особым от той не отличается?

– Это вы вспомнили таблицу Сивцева. В ходе теста на остроту зрения доктора во всем мире используют таблицы для определения того, как вы видите на расстоянии в сравнении с другими. Классической считается таблица голландца Германа Снеллена (Hermann Snellen), разработанная им еще в 1860-х годах. Есть много ее вариаций, но в основном они показывают 11 рядов заглавных букв. Верхний ряд состоит из одной буквы – обычно это большая 

, остальные – из прогрессивно уменьшающихся букв. Когда врач проверяет зрение, он просит вас назвать самые маленькие, которые вы различаете. Если вам удалось разглядеть без бинокля буквы самого нижнего ряда, вас остается поздравить и отпустить на волю. Если других проблем нет. 

Почему этот результат называют 20/20, не 1000/1000 или просто «супер»?

– Нумератор, т.е. верхняя цифра, означает дистанцию, при которой идет определение. В Штатах и в Англии используются футы – 20. В Европе и России метры – 6. Для зрительной системы человека 20 футов или 6 метров – это уже «бесконечность», т.е. на этой дистанции лучи света параллельны. Все, что дальше 20 футов (6 метров), лишь уменьшается в восприятии. Денумератор (нижняя цифра) показывает, насколько хорошо вы видите по сравнению с "нормальным" человеком. Тем самым 20/20 означает нормальную остроту зрения. 

– Если у вас 20/20, вы видите с 20 футов то, что условный "нормальный" человек и должен видеть с 20 футов. В этом случае ваше зрение – «единица» , 20/20=1. Или, соответственно, 6/6 в стране с метрической системой: 6/6=1. Если ваше зрение 20/40 (минимум, необходимый для получения водительских прав в большинстве штатов), это означает, что вы видите с расстояния 20 футов то, что человек с "нормальным" зрением видит с 40 футов. Если зрение 20/100, то вы видите с 20 футов то, что «нормальный человек» видит со 100. То есть "нормальный" увидит заданный объект со ста футов, а вам с вашим зрением 20/100 придется подойти в пять раз ближе, на 20 футов, чтобы увидеть то же самое. 

– Упомянутая вами буква E на некоторых таблицах начинает заниматься акробатикой, крутясь на 90 градусов своими палочками то в ту, то в эту сторону. Рассчитано на детей?

– Или на взрослых, которые по разным причинам не могут прочесть буквы вслух. Скажем, стесняются или просто не разговаривают – не только немые, но и страдающие аутизмом. В этих случаях доктор просит просто показать рукой, в каком направлении расположены палочки. Есть еще и «Звезда Симменса» – изображение, применяемое для проверки остроты зрения. Она представляет собой пучок черных лучей на белом фоне, сбегающихся от периферии к центру. При нормальном зрении, рассматривая это изображение с определенного расстояния, вы увидите, как лучи начинают сливаться на половине своей длины. На большей дистанции они будут сливаться в сплошную серую массу по причине ограниченной разрешающей способности сетчатки. При аномалии рефракции лучи расплываются. Люди с хорошим зрением могут наблюдать подобный эффект, если поднесут «звезду» очень близко к глазам. 

Ну хорошо, теперь поговорим о нас – людях, которые отродясь не могли разглядеть нижнюю строчку ни с 20 футов, ни с 6 шагов. Какие цифры обозначают «нехорошее» зрение?

– Глазные таблицы подвергаются различным интерпретациям, но в общем и целом, если вы можете прочесть только верхнюю 

 и ни одной буквы ниже нее, то ваше зрение оценивается как 20/200. Это означает, что с 20 футов вы различаете букву, которую люди с «нормальным зрением» увидят с 200 футов. Так что зрение 20/200 – очень плохое. 

Бывает и хуже, хотя это то еще утешение.

– Есть более сильное утешение – помощь опытного офтальмолога, оснащенного феноменальной современной техникой. 

А кто в Штатах считается legallyblind, т.е. официально слепым?

– Если острота вашего зрения после максимальной коррекции, т.е. в очках или контактных линзах, достигает лишь упомянутых 20/200 или еще хуже. 

Какую конкретно строчку я должен видеть, если претендую на 20/20?

– Таковой обычно считается четвертая строчка снизу, а еще ниже идут, соответственно, 

. Немногие люди могут похвалиться остротой зрения 

, но существует множество животных и особенно хищных птиц, – о чем мы с вами толковали в прошлых беседах, – которые заткнут за пояс и самого зоркого хомо сапиенса. 

Говоря о зоркости, в том же, не к ночи будь сказано, СССР были еще и такие, знаете, текстики со шрифтиком все мельче и мельче.

– Это Jaeger Eye Chart (таблица Йегера), состоящая из блоков текста разного шрифта и размера. Шкала варьирует от J1 до J11 или больше. J1 считается самым крошечным, а J2 приравнивается к остроте зрения 20/20 при чтении на расстоянии 12 -14 дюймов от ваших глаз. 

А если есть такие уже проверенные в веках таблицы, зачем офтальмологу все это фешенебельное оборудование?

– Во-первых, "измерить" зрение – это не измерить рост. Зрение – сложнейший процесс, которому у высших приматов и у человека отведено 20% мозговой поверхности. Качество зрения очень не просто измерить, а еще сложнее сравнивать между людьми. Во-вторых, передать качество зрения в одном измерении невозможно. Многие по привычке используют проценты. «У меня 80% процентов зрения». Это неправильно. Качество невозможно передать одним числом или даже дробью. Зрение как таковое состоит из множества параметров. 

 – насколько четко вы видите на данной дистанции, т.е. какие самые маленькие буквы можете различить. Хорошее зрение включает в себя возможность видеть остро. 

 зрения или поле зрения, которая поражается при таких заболеваниях, как глаукома, перерождение сетчатки, инсульты и т.д. 

 – на каких расстояниях пациент может различать увиденное. Этот параметр обычно начинает ухудшаться после 40 лет с развитием пресбиопии. 

понижается с развитием катаракт и рубцов на роговице. Ну и 

. Нужно понимать, что разные заболевания поражают различные параметры или аспекты зрения. Катаракты, глаукома, заболевания сетчатки требуют совершенно разного подхода в измерении зрительной функции. 

– Таблицы помогают измерить лишь остроту зрения. На основе применения таблиц DMV (Автотранспортная Инспекция) определяет, можете ли вы водить машину, или признает вас «официально слепым». На этом функции таблиц Снеллена или Йегера кончаются. Они не могут ничем помочь в исследовании периферийного зрения, восприятия глубины, цветового восприятия и различения контраста. И они не имеют отношения к вопросам о состоянии здоровья ваших глаз, таких, как внутриглазное давление, есть ли у вас глаукома, нет ли у вас катаракты, насколько сухи ваши глаза, в каком состоянии находится ваша сетчатка. Глазные таблица – лишь малая часть комплексного обследования, которому – в случае если ваши глаза вам не совсем безразличны – стоит прибегать хотя бы раз в год.

Что такоеƎ 20/20?

Расшифровывание 20/20 с первого взгляда может приравняться к дифференциальным уравнениям. Без паники, здесь все четко и на примерах. 


Что такое 20/20?

Maybe the best eye center ever. They care about the patient, service is personalized and awesome. Cannot possibly recommend more! Will never consider another doctor.

Staff was very personable and accommodated my needs.  Dr Benjamin was very professional and great bedside manner.  I would highly recommend the office to friend and family

Dr Benjamin and his staff are World Class and second to none! I been bringing my mother to see Dr Benjamin and just recently became a patient myself. If you want to extend the quality of your vision and therefore the quality of your life, go see Dr Benjamin!

Class One from A to Z. Each and everyone from the doctor, optometrists, front office and back office, are professional, super knowledgeable, detailed, and very kind. The office is most elegant with beautiful lighting , equipment and furniture. The glass frames are  the most beautiful you will ever see.

An awesome experience as is the norm for our visits to Dr Benjamin. We have trusted him and his office with our multiple surgeries and care for many years, and plan to continue forward. Thank you Dr Benjamin, and your staff.

I’ve been going to Dr. Benjamin for years. He is straight-up honest, very patient in explaining, thorough, extremely experienced and is a Top Pro in his biz. I went to him for my eyeglass prescriptions for years, and then eventually had multifocal lens surgery in both of my eyes. All went great and to plan! His staff are extremely courteous, friendly, and very helpful. I’ve never done this at a doctors office, but I actually complement his staff in person often. I highly recommend this office. 100%

Great front desk and tech staff. The doctor was super nice and I’m so pleased I found this eye institute! Everyone was great and happy to finally have taken care of an appointment I had been putting off for a while. Great check-in process also for first time patients.

⭐️ My review of LASIK after one year ⭐️I told Dr. Benjamin I would do this a while ago, but I kind of feel like it says a lot I have kept this on my checklist for a year. I feel like a year is a good amount of time to review a procedure like this and give my honest thoughts and recommendation.So, let me tell you about my journey to getting LASIK and how I ended up in the amazing care of Dr. Benjamin. After going to an optometrist for years and him advising against LASIK because of my genetically dry eyes, I finally got a second opinion from an ophthalmologist (Dr. Benjamin). I didn’t know the difference between an optometrist vs. opthalmologist, but once I learned it kind of made sense why my optometrist didn’t want me getting LASIK lol. Because he couldn’t sell me on contact lenses or glasses for the foreseeable future if I got my vision corrected :) I mean, who knows, but I am glad I got a second opinion.I figured being in Los Angeles with some of the best doctors in the world… if anyone is going to touch my big, blue eyeballs, might as well get it done while I’m here. I found this business due to the reviews and they seemed to really know what they were doing and how to talk to clients.Upon meeting Dr. Benjamin he told me that I wasn’t a candidate for LASIK with my dry eyes, but he could put me through treatments for dry eyes and reevaluate after; and that these treatments had a good success rate for most.So, I started doing two treatments every other week for about 2.5 months - IPL laser treatment and Lipiflow. Lipiflow, especially, was a weird painless experience but highly recommend anyone with dry eyes to ask about it regardless of LASIK. I could tell my eyes felt way less dry a couple days after each treatment. There are videos on YouTube that talk about this treatment… Who knew this stuff existed. I’m not gonna lie, it’s an investment to do all these treatments on top of LASIK, but my eyes rarely feel dry anymore so if you’re going to get it done - do it right.Finally, I was approved for LASIK. I ended up waiting until the end of year to make sure I saved up the funds to do it and had some time to heal. I also took advantage of an end of year deal they were offering. $1000 off was a pretty nice forcing function to get me to finally do it after prepping my eyes with the treatments. The procedure itself I couldn’t feel anything even though I was awake the entire time (medicated). Even the scary part when bubbles form on your eyes Dr. Benjamin let me know about in advance so when it happened I just went with the flow. I think the worst part was the recovery the few days after and coming home drugged up lol. I remember day 1 thinking omg what did I do to my eyes. My eyes just hurt and felt weird, but omg I could see 20/15 immediately. And then, day by day it gradually got better. It took a few weeks for my eyes to heal, but after 1 month you couldn’t even tell I had surgery. One eye was a bit more bloodshot than the other.I can see 20/15. It’s been life changing for the past year not having to worry about contacts or glasses. I just got married and was able to walk down the aisle with clear vision. I only wish I had the means to have done this earlier in life. If you’re considering it - do it! And definitely consider Dr. Benjamin to do it right.Lastly, to continue treating my dry eyes, Dr. Benjamin gave me an extra LipiFlow treatment, and also recommended I try punctal plugs (painless plugs inserted into your lids that help your tears last longer). He placed the plugs in my eyes under 5 mins. Wild.I heard from people during the LASIK process they have been nervous to get the procedure so I wrote this to help and because I think highly of this business for changing my life. And, some of the dry eye treatments I would’ve never known about had it not been for them. Again, I wish I would have had been able to do this years ago. It is so, so worth it!Thank you, Dr. Benjamin (and staff!)

Concerned about a reoccurring virus, I text Dr Benjamin’s office first thing in the morning seeking immediate advice and an appointment. In quick time I received both sage advice and a same day appointment. Dr B takes a personal interest in his patients well being and has diligent, competent and attentive staff to support the care and support needed. Can’t speak highly enough.

Hi all! 06/06/2024 I came to the office of Dr. with a problem in my right eye. Benjamin, I'm sorry...as a very nice girl from the office, Masha, told me, he was undergoing surgery.  She advised me to come urgently in the morning. I suffered from pain for 4 days, my eye was very swollen, red and itchy. 07/06/2024 after examining me Dr. Benjamin made an emergency decision to remove the pus in his right eye. The small operation lasted 10 minutes, Dr. Benjamin and Dr. Svetlana masterfully removed the pus. My torment is finally over! Thank you to the entire team at Benjamin Eye Institute. You are the best, true professionals in your field. I wish you further success and good luck in your very necessary and difficult work! You give people a new stage of life! Thank you for that!

Been going to Dr B for nearly a decade after trying many other eye doctors in LA.  Beyond solving my chronic dry eye and being the most knowledgeable, he is an all-around great guy and spends time educating. The staff is wonderful as well.

The ophthalmologist that performed my surgery, Dr. Benjamin, was extremely skilled and knowledgeable. He took the time to thoroughly explain the procedure and answer all of my questions. I felt confident in his abilities and knew that I was in good hands.

Dr Benjamin and his team are extremely professional. I had Lasik surgery performed by him and his team and everything to date has gone exactly as described to me. Front office is very friendly and scheduling appointments is easy.

Great staff, great doctors, excellent ophthalmologists and assistants. The optical department for where you get glasses is very good. You may pay a little more, but you get excellent service, both at the optical boutique, and of course with your exam.They have the most advanced equipment in the industry. And the optician knows what she's doing. Overall, I really like this place and will continue to have them examine my eyes and purchase Glasses there. Dr. Yakubin, along with Dr. Benjamin are great and caring. Kathy and Rina also take good care of your needs. Finally the front desk staff is extremely helpful and also caring. It is a great experience to make sure your eyes and vision are taken care of.

The office staff were kind and considerate. The technician that assisted me explained everything she was doing. The Doctor was very nice and explained everything. He was definitely knowledgeable about my condition.

Dr Benjamin has been the “go to” eye specialist for 3 generations of my family, starting with my father and now grown children. Simply put, he’s an exceptionally capable, trustworthy, and cutting edge doctor with a courteous and professional staff.Without any reservations, I recommend him to anyone seeking an exceptional eye doctor.

The surgeons at Benjamin Eye Institute are true experts in their field - they were able to explain the procedure in detail and answer all of my questions and concerns. The surgery itself was quick and painless, and the recovery was much faster than I had anticipated.

I just completed my first visit and can say that this office deserves every high ranking it gets. The staff are efficient, friendly but highly professional.  The office is modern and sparkling clean. The examination was smooth and thorough. The doctor saw me on time.  He listened closely to the background of my problem, and he clearly communicated his treatment plan and the rationale for it. I absolutely trust him and highly recommend him.

I had my first visit with Dr. Benjamin today and it was amazing from start to finish. The office itself is immaculate and everyone I interfaced with was super friendly and professional. This includes Dr. Benjamin. He was extremely thorough and spent a lot of time with me as a new patient. I look forward to being under his care for years to come. I highly recommend this practice to anyone in need of an ophthalmologist in the LA area.

Dr. Benjamin is always personable and thoughtful and very much an expert.  He has been my eye doctor for many years.  Now that I am older I am very grateful that he is still my ophthalmologist. Everyone in the office is very helpful. I, of course, highly recommend Dr. Benjamin.

One of the things that sets the Benjamin Eye Institute apart from other ophthalmology practices is their team of experienced and highly trained surgeons. The surgeons at the Benjamin Eye Institute have performed thousands of cataract and LASIK surgeries, and have a wealth of experience in these procedures. They are committed to providing the best possible care for their patients and strive to achieve excellent outcomes.

Dr. Benjamin and his staff were amazing. Everyone was friendly and professional! I didn’t feel rushed during my appointment and Dr. Benjamin  took the time to explain everything and answer questions. His assistant who helped in doing all of the eye tests was great, too! Happy to have found a great eye doctor!

No exaggeration, this was the best visit with any doctor I've ever had. The facility is very nice, the staff is exceptionally thorough, professional, and efficient and Dr Arthur had by far the best bed side manner I've ever encountered. I 100% recommend him and his team

My experience at Benjamin Eye Institute was exceptional.  I’m not sure if I’ve ever encountered such an efficient and professional staff in a doctor’s office.  The front desk was communicative and everyone up to the doctor was beyond detailed in their care.

The entire team takes the time to discuss and explain treatment options.  Highly recommended!

Immediately after  cataract surgery, I can see my husband’s face accross the room for the first time in 40 years! No more glasses since childhood, both distance and close up. If you are thinking, should you spend the big bucks to see everything both near and far?  I can tell you it’s so worth it! Thank you Dr. Benjamin and all the wonderful people in your office! I appreciate your efficiency, attentiveness, professionalism and welcoming space! Please feel free to use me as a reference any time!

With expert staff, modern surroundings and equipment, this is the doctor of choice in Los Angeles. After over 15 years i can attest to Dr. Benjamin's superior expertise in cataract removal and implants. I love the new treatments. State of the art.

Dr Benjamin and Alba were great. He is very professional, kind and with clear explanations. I had an eyelid quick surgery and I’m just missing the glasses prescription, I left the office and forgot to ask for it. But he and his team were amazing!

I was referred to Dr. Benjamin from both my eye doctor and a very close friend of mine who also had her LASIK performed there. My experience was exceptional. Every single person that you meet in the office is a joy to work with. Whether it was the constant and clear communication, or the fact that they were always listening to feedback and answering my questions and concerns, they went out of their way to make me feel comfortable trusting my vision to them. They were very kind and never once pressured me into anything (including when I had to push my surgery back after I broke my leg).I would recommend this place to anyone who has eye problems because they have the most advanced equipment and Dr. Benjamin is caring, thorough and knowledgeable.

Top notch service and staff! By far the best experience I’ve had at a doctors office in 20 years. I wish every office was as well trained, friendly, and professional as Benjamin Eye Institute. Seriously if you have eye problems you won’t find a better doctor.

More than everything I value professional people. Dr. Arthur Benjamin is one of them. He is taking care of me and my husband for pretty long time. All I can say we are very thankful to the doctor and people who work as a team to make us healthy and happy !
