I had a discussion with optometrist Bryan Smith the other day, in which he mentioned the concept of ‘maladaptation’ in reference to eyesight. In which people who are using their eyes at close distances on a fairly constant basis (computers of all sizes, phones, deskwork, TV etc) are developing distance blur. So if we are using our eyes for a limited range of distances, they begin to adapt, or in this case ‘maladapt’ (where the change is not beneficial) to that usage, that specific type of function, and begin to lose the wider ranges of function they originally had.
This really illustrates the importance of maintaining a balance of activities and of using the eyes at a variety of distances on a regular basis. This is easy to say, but how do we make the shift from almost never to consistent practice in daily life? In order to make this happen, we need to start with good thinking habits. Because the decisions to actually do the things that keep your eyes in balance will start with your brain, and your mind.
I feel it is important to remember the particular way the brain operates, as this influences our perceptions about being able to change our thinking habits. If we think of ‘the way that we respond to things’ as being an entirely inevitable part of ‘ourselves’, it may give us the idea that our thinking habits cannot be changed. But we are discovering that the brain is changeable, it can form new connections. This can help us to understand that many of our responses are habitual, not inherent.
The brain utilizes neural ‘pathways’, so if you think a particular thought, then you will fall into the pathway that is your regular journey from that thought. So if you notice, ‘My eyes feel a bit strained’ (say after hours at the computer), the question is, do you have a habitual pathway from there that says ‘I will stop and do 5 minutes of Near Far Swing and a bit of Palming’, or do you have a thought pathway that says ‘I will just keep pushing on until the day is over’?
If you have the first habitual thinking pathway, then you probably are maintaining your eyes reasonably or very well. If you have the second, then you may find yourself with increasing eye strain and needing increasingly stronger prescriptions to compensate for the tension in the visual system.
Changing these pathways is a matter firstly of becoming aware of your habits, then making a conscious choice to do something different. This difference then needs to be maintained on a consistent basis in order for the new pathway to become established, and then become the pathway that is automatically taken.
Body habits will follow these thinking habits quite naturally. When you are out and about, if you practice visually sketching off into the distance deliberately and consciously at regular intervals (rather than just focusing on things close to you), then with consistent practice your eyes will start to do this without you having to think about it. Remember to blink, breathe and stay relaxed with this practice.
Even aside from having a schedule which allows for some regular vision activities at various times of the day, there are a number of ways that vision students find it useful to remind themselves to keep reinforcing their good vision habits throughout each day.
One technique is to use notes to yourself posted in important places. They can be as simple as reminders to breathe, to blink, to ‘sketch’ rather than stare, to let the neck and shoulders be soft.
It may also be beneficial to have these reminders in two formats. The form of written words, which will activate the left side of the brain where new learning takes place, and the form of pictures (say of a face with a Magic Nose Pencil on it) to activate the right hemisphere of the brain, where long term habits live. They can be placed around the computer monitor, on the refrigerator and on the dashboard of the car, anywhere that you may find useful.
It may also be important to change the notes and locations regularly so they don’t become part of the unnoticed ‘furniture’ of your visual spaces.
Just as you need to balance your long periods of sitting at the computer with physical exercise to keep good function in the whole body, you also need to balance the bulk of near work of your eyes with relaxed use at various distances. One of my favourite ways to combine these two is with outdoor walks where you can delight your eyes with long vistas, and ‘dance’ them around trees, flowers and whatever else you can find to keep them, and yourself, interested and moving.
Tell us how you help yourself to remember your good vision habits and maintain the balance of use and function for your eyes.
