Welcome to an engaging exploration of focus and attention, inspired by insights from Andrew Huberman, a professor of neurobiology and ophthalmology at Stanford School of Medicine. In this article, we’ll delve into the fascinating connection between visual focus and mental focus, and how you can harness this relationship to improve your concentration skills.
One of the most effective ways to enhance your focus is by leveraging the natural mechanisms of focus that you possess. A key principle to understand is that mental focus is closely linked to visual focus. You might have noticed how your visual attention can be scattered or intensely concentrated on a specific point. This visual focus is crucial for accessing neuroplasticity, the brain’s ability to reorganize itself by forming new neural connections.
Focus begins with alertness, which can be triggered by emotions such as love, joy, or fear. Caffeine is a common pharmacological method to boost alertness by reducing adenosine, a molecule that induces sleepiness. While caffeine can safely increase alertness, other substances like Adderall, which resembles amphetamine, are often misused. Although Adderall can enhance alertness, it doesn’t directly improve focus as it doesn’t engage the acetylcholine system, which is crucial for focus.
To improve focus, you can engage in behavioral practices that involve visual concentration. When focusing visually, you have two choices: concentrate on a small, detailed area or broaden your gaze to encompass a larger, less detailed view. This trade-off is due to the structure of the eye, where the fovea, a small central pit, has the highest density of light receptors, providing sharp vision.
Try this simple experiment: hold your hands in front of you and count your fingers. As you move your hand to the side, you’ll notice a decrease in clarity, which improves as you bring your hand back to the center. This demonstrates the higher density of receptors in the center of your visual field compared to the periphery.
To boost cognitive focus, practice visual concentration at the distance relevant to your task. For instance, if you’re reading a scientific paper, spend 60 to 120 seconds focusing your visual attention on a small area of the text. This practice can enhance visual acuity and activate brain regions involved in information processing.
If you wear corrective lenses, ensure you use them during these exercises. The clearer the visual image and the longer you maintain your gaze, the better your attention levels will be. As you tire, blinking increases, but reducing blinks and concentrating on a specific point can enhance mental focus.
Attention is a skill that can be developed and is essential for effective learning. It’s important to balance focus with breaks, as even high-performing individuals don’t maintain intense focus all day. Consider utilizing ultradian cycles, which last about 90 minutes, for learning sessions. During these periods, minimize distractions by turning off Wi-Fi or putting away your phone.
As attention drifts, re-anchor it using visual focus. Identify the times of day when you’re most alert and use those periods for concentrated learning.

Conduct a hands-on experiment to understand the relationship between visual and mental focus. Hold your hands in front of you and count your fingers while moving your hand to the side. Observe the changes in clarity and discuss how this relates to the density of light receptors in the eye. Reflect on how this understanding can be applied to improve your concentration skills.
Engage in a group discussion about the role of caffeine in enhancing alertness. Share personal experiences and research the effects of caffeine on adenosine levels. Debate the pros and cons of using caffeine versus other substances like Adderall for improving focus. Consider the ethical implications and health impacts of these choices.
Practice visual concentration by focusing on a small area of text for 60 to 120 seconds. Use this exercise to enhance your visual acuity and activate brain regions involved in information processing. Reflect on how this practice affects your ability to concentrate on academic tasks and discuss strategies to incorporate it into your study routine.
Organize study sessions based on ultradian cycles, lasting about 90 minutes. During these sessions, minimize distractions by turning off Wi-Fi and putting away your phone. After each session, take a break and reflect on how this approach affects your learning and focus. Share your experiences with peers and adjust your study habits accordingly.
Keep a journal to track your attention levels throughout the day. Identify the times when you are most alert and use these periods for concentrated learning. Record your observations and reflect on how visual focus techniques help re-anchor your attention. Use this journal to develop personalized strategies for enhancing your learning experience.

[Music] Welcome to another episode of After Skool. I’m Andrew Huberman, professor of neurobiology and ophthalmology at Stanford School of Medicine and the host of The Huberman Lab podcast. Today, we will be learning about how to improve focus and attention. So, without further ado, let’s watch the animation.
The best way to get better at focusing is to use the mechanisms of focus that you were born with. The key principle here is that mental focus follows visual focus. We are all familiar with the fact that our visual system can be unfocused, blurry, or jumping around, or we can be very laser-focused on one location in space. What’s interesting and vitally important to understanding how to access neuroplasticity is that you can use your visual focus and increase your visual focus as a way of enhancing your mental focus abilities more broadly.
Plasticity starts with alertness. That alertness can come from a sense of love, joy, or even fear. There are pharmacological ways to access alertness too; the most common one is caffeine, which reduces a molecule that makes us sleepy called adenosine. Caffeine can be a relatively safe way to increase epinephrine.
Many people are also using Adderall, which chemically resembles amphetamine and essentially is amphetamine. It increases epinephrine release, waking up the brain. While it has a basis for use in certain clinical syndromes, it also has a high probability of abuse, especially in those who are not prescribed it. Adderall increases alertness but does not directly enhance focus, as it does not affect the acetylcholine system.
The acetylcholine system and the focus it brings can be accessed through pharmacology and behavioral practices. Behavioral practices anchored in visual focus will allow you to develop great depth and duration of focus.
When we focus visually, we have two options: we can look at a very small region of space with a lot of detail or we can dilate our gaze to see larger areas with less detail. This is a trade-off; we can’t look at everything at high resolution. The pupil relates to the fovea of the eye, where we have the highest density of receptors that perceive light. Our acuity is much better in the center of our visual field than in our periphery.
You can try a simple experiment: hold your hands out in front of you and see how many fingers you can count. If you move your hand to the side, you may not see it with precision, but as you bring it back to the center, you can see it clearly. This is because the density of receptors in the center of your visual field is much higher than in the periphery.
When we focus our eyes, we tend to do so in the center of our visual field, and our two eyes align in what’s called convergence. The lens of our eye adjusts so that our brain sees a small cone of visual imagery, which has much higher acuity than if we were to look at everything at once.
Focus in the brain is anchored to our visual system. If you want to bring about higher levels of cognitive or mental focus, you need to practice focusing your visual system. This works best if you practice focusing your visual system at the precise distance from the work you intend to do.
For example, if you’re trying to concentrate on reading a science paper, you might think you’re only looking at the paper, but your eyes may be darting around. Spending just 60 to 120 seconds focusing your visual attention on a small window of your screen can increase your visual acuity and activate brain areas associated with gathering information.
If you wear corrective lenses, be sure to use them while practicing visual focus. The finer the visual image and the longer you can hold your gaze on it, the higher your levels of attention will be.
As we get tired, we tend to blink more, which is a natural response to keep our eyes lubricated. However, if you can maintain focus by blinking less and concentrating on a specific location, you can enhance your mental focus.
When people listen attentively, they often close their eyes. This is not a coincidence; closing the eyes helps create a cone of auditory attention.
Attention is something that can be learned, and it’s critical for creating conditions where whatever you engage in will modify your brain. You should also consider whether you’re trying to focus too much for too long during the day. Many high-performing individuals do not focus all day long; they take breaks and engage in other activities.
In earlier discussions, I mentioned ultradian cycles that last about 90 minutes. A typical learning session should be about 90 minutes, including a warm-up period. During this time, you should eliminate distractions, such as turning off Wi-Fi or putting your phone away.
Attention drifts, but we need to re-anchor it. If you’re sighted, you can do this with your eyes. As your attention drifts, try to maintain visual focus on the task at hand.
It’s essential to be alert when learning. Consider when during your day you are most alert and use that time for focused learning.
