Do You See Marilyn Monroe or Albert Einstein? This Reveals How Good Your Eyesight Is

Do You See Marilyn Monroe or Albert Einstein? This Reveals How Good Your Eyesight Is

Want to test your eyesight with this hybrid image?

    Who do you see when you look at the image from a regular viewing distance?

    Is it Marilyn Monroe or Albert Einstein?

    If there is someone around, ask them who they see.

    Now, start taking steps back as you look at the image.

    Does the image change?

    Who do you see now?

    Or, try squinting your eyes and look at the photo.

    You probably won’t be surprised to hear that the person most people see when they are close to the image is Albert Einstein, however, not everyone gets to maintain the same image as the distance changes. As they get farther away from the image, most people are shocked by the sudden transformation of Albert Einstein into Marilyn Monroe. The same happens if you change the size of the image, in which case the smaller one will be perceived as Marilyn Monroe, whereas the bigger image will show clear details of Albert Einstein’s face.

    If you find it hard to find the face of Albert Einstein, chances are you need to see your eye doctor, as your eyesight probably isn’t very good. If you already wear glasses, then you need a stronger ones.

    For the rest of you, who clearly see Albert Einstein at first, your eyesight is as good as you can keep the unchanged image.

    How hybrid images determine our eyesight

    The image above, created by Dr. Aude Olivia from MIT is a hybrid image which is made by taking two separate images and combining low spatial frequency components of one with high spatial frequency components of the other. In this way, as we are closer to the image, we can more easily spot the fine lines and details (in this particular case the wrinkles on Albert Einstein’s face), whereas if the image gets smaller, or if we look at it from bigger distance, our eyes are only able to see general details like shape of hair, mouth or nose, features that, in this case, belong to Marilyn Monroe.

    The author of the image explains the concept of hybrid image:

    “The phenomenon of hybrid images arises from the multi-scale processing of images in the human visual system. By taking into account perceptual grouping mechanisms, one can build compelling hybrid images with two different stable interpretations: one that appears when the image is viewed up-close, and the other that appears from afar.”

    The explanation of how hybrid images are able to determine the quality of our eyesight lies in the fact that our ability to focus and see clear, fine details from any distance defines good eyesight. Therefore, people who struggle with blurred image even at regular viewing distance, should consider seeing an eye doctor.

          The Ultimate Guide to Help You Sleep Through the Night Tonight

          The Ultimate Guide to Help You Sleep Through the Night Tonight

          It’s well past midnight and you’ve got to get up in less than six hours. You toss and turn all night. Before you know it, another hour passes by and you start panicking.

          If I don’t get to sleep in the next 30 minutes, I’m going to be exhausted tomorrow!”

          One thing is for sure, you’re not alone. Over 70M+ Americans have stated that they don’t get the proper sleep they need at night.[1] So what could possibly be causing this insomnia epidemic?

          Throughout my entrepreneurial journey of building my language learning company, I have experimented and researched dozens of best sleep practices. Some have flopped but a few have dramatically improved the quality of my life and work.

          In this article, I’ll look into the reason why you’re sleep deprived and how to sleep through the night tonight.

          Why you can’t sleep through the night

          The first step to improving anything is getting to the bottom of the root problem. Different studies have shown the reasons why most people cannot sleep well at night.[2] Here are the main ones that the average person faces:

          Advertising

          Stress

          If you’ve ever stayed up at night worrying about something, know that it’s a major sleep inhibitor. When you’re feeling stress, your mind and body becomes more activated, making it incredibly difficult to fall asleep. Even when you do manage to sleep, it won’t be deep enough to help you feel rested the next day.

          Exposure to blue light before sleep time

          We’re exposed to harmful blue light on a daily basis through the use of our digital screens. If you’ve never heard of blue light, it’s part of the visible light spectrum that suppresses melatonin, our sleep hormones. Other harmful effects include digital eye strains and macular cellular damage.

          While daytime exposure to blue light is not very harmful, night time exposure tricks our brain into thinking it’s daytime. By keeping your brain alert and suppressing melatonin, your mind is unable to shut down and relax before bedtime.

          Eating close to bedtime

          Eating too late can actually be an issue for many people, especially those who are older than 40. The reason is, eating before laying down increases the chances of Gastroesophageal reflux disease (GERD), in which stomach acid backflows into the esophagus.

          Another reason not to eat too late is sleep quality. Even if you manage to sleep right after eating, it’s likely that you’ll wake up tired. Instead of letting your body rest during sleep, it has to digest the food that was entered before bedtime.

          Rule of thumb: eat 3-4 hours before bedtime.

          Medical conditions

          In some cases, it could be medical conditions that cause your sleep problems. If you can’t relate yourself to the above reasons or any of these common sleep problem causes, you should visit the doctor.

          The vicious sleep cycle

          The biggest danger to repeating the bad habits mentioned above is the negative cycle that it can take you through. A bad night’s sleep can affect not only your energy but your willpower and decision making skills.

          Here’s an example of a bad sleep pattern:

          You get a bad night’s sleep
          –> You feel tired and stressful throughout the day.
          –> You compensate it with unhealthy habits (for example junk food, skipping exercises, watching Netflix etc.)
          –> You can’t sleep well (again) the next night.

            You can imagine what could happen if this cycle repeats over a longer period of time.

            How to sleep better (throughout the night)

            To help you break the vicious cycle and stop waking up in the middle of the night, I’ll explain to you a list of actionable steps to solve your trouble staying asleep.

            1. Take control over the last 90 minutes of your night

            What you do (or don’t do) before bedtime have significant impact on the quality of your sleep. Many times, it can be the difference between staying up until 4am and sleeping like a baby.

            Here are a few suggestions:

            • Go from light to dark – Darkness stimulates production of the sleep hormone melatonin. Turn off unused light around the house, and think about investing into warm light that you can use in the bedroom before bedtime.
            • Avoid screens (or wear blue light blocking glasses) – Keep the bedroom a technology-free zone as the light from electronic devices can disturb your sleep. If you need to work, wear blue light blocking glasses (also known as computer glasses) throughout or before you sleep to prevent sleep disruption.
            • Find an activity that helps you to wind down  This could be anything that calms you down, and reduces thinking (especially unnecessary stress). Fir example, listening to soothing/good feel music, taking a hot bath, reading or meditating.
            • Keep any electronics you have on the other side of the room or outside the room – One of the most harmful things that can disrupt your sleep is the notifications you get from your smartphones. The simplest way to avoid this is to keep it away from you.
            • Create a bedtime routine – A night routine is a couple of things you do prior to going to bed. By doing these things every night, you’ll have a more restful and high-quality sleep.

            2. Eat the right nutrients (and avoid the wrong ones)

            What you eat (not just when we eat) plays a critical role in your sleep quality. If you’re ever in doubt of what to eat to improve your sleep, take the following into consideration:

            • Kiwi – This green fruit may be the ultimate pre-bed snack. When volunteers ate two kiwis an hour before hitting the hay, they slept almost a full extra hour. Kiwis are full of vitamins C and E, serotonin and folate—all of which may help you snooze.
            • Soy foods – Foods made with soy such as tofu, miso and edamame, are rich in isoflavones. These compounds increase the production of serotonin, a brain chemical that influences the body’s sleep-wake cycle.
            • Fiber-rich foods – Eating more fiber could be key for better sleep. Eating fiber was associated with more restorative slow-wave sleep—the more you eat, the better you sleep—per a study published in the Journal of Clinical Sleep Medicine. Fiber prevents blood sugar surges that may lower melatonin. Get a fiber boost from beans, artichokes, bran cereal and quinoa.
            • Salmon – Most fish, especially salmon, halibut and tuna boost vitamin B6, which is needed to make melatonin— a sleep-inducing hormone triggered by darkness.

            3. Adjust your sleep temperature

            Once you’ve gone through the first 2 recommendations, the last step to experiment with is temperature. According to Sleep.org, the ideal temperature for sleep is 60-67 Farenheit. This may be cooler than what most people are used to, but keep in mind that our body temperature changes once we fall asleep.

            Rule of thumb: sleeping in cooler temperature is better for sleep quality than warmer temperature.

            Congrats on making it to the end of this guide on sleep. If you’re serious about taking the necessary steps in improving your sleep, remember to take it one step at a time.

            I recommend trying just one of the steps mentioned such as taking a hot bath, blocking out blue light at night, or sleeping in cooler temperature. From there, see how it impacts your sleep quality and you can keep doing what works, and throw away what doesn’t.

            As long as you follow these steps cautiously and diligently, I know you’ll see improved results in your sleep!
