Up to 4% of US citizens suffer from a lazy eye. [1]
So did I.
I was born with a lazy eye. And like many other people tormented with said condition, I've asked myself many questions:
In this blog post, we will explore the question of whether a lazy eye is genetic, and what the latest research says about the causes and treatment of this condition.
Strabismus, often called lazy eye, means that a person has misaligned eyes.
Meaning: Both eyes are not pointing in the same direction (either due to muscular issues, or brain issues - or both in summation). [2]
While 'lazy eye' and 'strabismus' is technically not the same thing - 'lazy eye' is amblyopia [3] , and strabismus is 'eye misalignment' - it's often used interchangeably. So, in this article, I'll be using both terms interchangeably as well.
There are many symptoms to having crossed eyes:
To people with strabismus, this is socially unpleasant, and makes normal things such a finding a partner more difficult for the patient. As humans have evolved to favor symmetry in their significant others. [4]
This is why the number one reason for surgery in adult strabismus is psychosocial (in plain English, this means for social reasons/ interacting with others). [5]
And this is also why most people with strabismus are concerned about passing it down to their offspring: They typically do not want their children to be bullied, or have to deal with the same social alienation as they did.
Additionally, strabismus can lead to amblyopia:
Amblyopia is characterized by permanent blurry vision in the weaker eye. The severe amblyopia (significant loss of visual acuity) is the worst thing that can happen when you have strabismus. [6]
The reduced vision in one eye due to amblyopia is usually permanent. I've personally lost 80% of my visual acuity in my left eye, and so far have not managed to re-gain it.
A common cause of a lazy eye is the child being born too early [7], or a family history of eye disorders.
For me personally, it was the pre-term birth thing. I was born a few weeks too early, which seemed to have prevented proper neurological development of the visual center. And as a result, has created long-term vision problems.
So while strabismus in my family history is not obvious, it is generally accepted that it takes both genetics and environment to create strabismus.
The best study in regards to the inheritability of strabismus is called: Genetic Basis of Congenital Strabismus. [8]
What are the findings of that study?
If you double a low risk, it still stays low.
Life is risky, and it takes both genome and environment to create strabismus. So, the fear of giving strabismus to your kids is not a good enough reason to not have kids.
Amblyopia (blurry vision of one eye) occurs typically once strabismus is present. So if strabismus - meaning the misalignment of both eyes is present - the chance of poor vision in one eye increases significantly.
Which means that amblyopia is indirectly hereditary - because strabismus to some extent is hereditary.
The same mechanism that causes the lazy eye (strabismus) in a newborn child, is likely to be at work as an adult.
This process is what causes lazy eye in adults:
In my opinion, the best way to live life is to graciously overcome all challenges that are thrown at you.
So while sometimes the card we're dealt with are not in our favor, it's our responsibility to play our cards well.
As a result, every person with a lazy eye should be focused to improve their condition. As this not only improves their quality of life [11], but due to epigenetics also that of their off-spring. [12]
The problem? Improving the condition is very:
So while vision therapy or surgery is a wonderfully effective treatment for strabismus/lazy eye - it is clear that a new first-line treatment is needed:
The goal of the Lazyeyefix Ai software is not to offer a treatment more effective than surgery. Frankly, it's impossible to offer something more effective than cuts in your eye muscles by a trained surgeon.
The goal of the Lazyeyefix Ai software is to offer an easy, at-home treatment to the 19 out of 20 people suffering from strabismus that are not yet ready to go for surgery.
We do so by offering a:
