Handbook
Vision tests
Check your vision on your own, at home.
A complete handbook of tests you run yourself, without a single device — to catch changes early and track your vision regularly at home.
This handbook is intended for children and adults with normal vision as well as for those who already wear vision aids. Poor vision is not hereditary and not forever if you decide to do something about it.
If you wear vision aids, it is essential to know whether the prescription correction is appropriate, too strong or too weak. Wearing an inadequate correction has long-term consequences. With the help of the tests you can also track whether the prescription is increasing in one or both eyes.
If you currently have no problem, it is important to know how to test your vision on your own so that the onset of an initial prescription is noticed in time. WHY? Solving 1kg of excess weight is not the same as 5kg or 10kg. It is the same with a prescription. At the very start, when the prescription is between 0.5 and 1.0, we are talking about two or three weeks of exercise and the prescription is a thing of the past. SO keep the vision tests with you and check your vision whenever you like at home.
What do you get?
We send the PDF Vision Tests Handbook and the files that need to be printed to your email.
The handbook covers these topics:
- How does vision really work?
- What to do when you notice your vision weakening (an initial prescription)?
- What even is normal vision?
- Wearing vision aids incorrectly
- Bad habits that affect vision
- Is poor vision hereditary/genetic?
- Is poor vision forever?
- Are we really doomed to glasses in older age?
The handbook includes instructions for testing vision at home:
- Nearsightedness (minus prescription)
- Farsightedness (plus prescription for reading and distance)
- Astigmatism (cylinders)
- Eye coordination (amblyopia, lazy eye, strabismus)
- Vision-aid strength test
Who are the tests for?
The vision tests are intended for adults of any age and for children from a minimum age of 7. Children younger than 7 do not distinguish the nuances of vision clarity and you cannot rely on their feedback, which may cause unfounded worry that there is a problem when the child is simply joking or does not understand what is expected of them.
Who are the tests not for?
The tests are not useful for children younger than 7 and for people who have a cataract or a loss of central or peripheral vision that causes part of the image to be missing from the visual field.
