Astigmatism is a common visual condition affecting millions of people worldwide, which is often diagnosed through a routine eye exam. It is characterized by an irregular curvature of the cornea or lens, leading to blurred or distorted vision. But did you know that astigmatism can also affect your depth perception? Yes, you heard it right! Here's a deep and concise dive into how astigmatism impacts depth perception and why it matters.
How Astigmatism Affects Depth Perception
When your vision is blurry at any distance, it can significantly impact your depth perception. This means you may find it difficult to judge distances correctly, keep your balance, or even read comfortably. Depth perception issues arise because your eyes rely on clear and focused images to gauge how far away an object is. With astigmatism causing blurred or distorted vision, your brain receives mixed and confusing signals, making it challenging in the process of stereopsis, i.e. making it difficult to perceive depth accurately.
Understanding Astigmatism
Could Astigmatism Be to Blame for Your Blurry Vision?
Absolutely, astigmatism is a refractive error caused by an irregular shape of the cornea or lens. Because of this abnormal shape instead of being perfectly round, the cornea or lens has an uneven curve, leading to blurred vision at various distances.
The Shape of Your Cornea is the Key in Astigmatism
The cornea is the transparent front part of your eye that helps focus light onto the retina. If the cornea has an irregular shape, it bends light unevenly, i.e. it makes the light focus on multiple focal points instead of just one focal point, hence causing astigmatism.
Astigmatism is a Common Refractive Error
Astigmatism is one of the most common refractive errors, alongside myopia (nearsightedness) and hyperopia (farsightedness).
Blurry Vision Isn’t the Only Symptom of Astigmatism
Apart from blurred vision, other symptoms of astigmatism include:
- Distorted or double vision (diplopia)
- Poor depth perception (which is a binocular dysfunction)
- Poor night vision
- Headaches and eye strain
- Squinting
Astigmatism May Run in Your Family
Just as we demonstrated with the genetic components of strabismus, astigmatism has also a genetic factor that increases the likelihood of it being inherited by offspring. In other words, If your family members have astigmatism, you may be more likely to have it too.
Factors That Can Contribute to Astigmatism
While genetics is a primary factor, other causes of astigmatism include:
- Eye disease
- Eye injury
- Eye surgery
- Keratoconus (a condition where the cornea thins and bulges into a cone shape)
Common Tips about Astigmatism you need to know
Sitting Too Close to the TV Doesn’t Cause Astigmatism 🤦♂️
No, contrary to popular belief, sitting too close to the TV does not cause astigmatism. This condition is primarily due to the shape of the cornea or lens.
Rubbing Your Eyes Could Be a Factor 🙅♂️
Frequent eye rubbing can exacerbate existing astigmatism by altering the shape of the cornea over time.
How Your Eye Doctor Treats Astigmatism [Overview of Professional Treatment]
Correcting Depth Perception Problems from Astigmatism
To correct depth perception problems caused by astigmatism, your eye doctor may recommend:
- Eyeglasses: Special lenses can help correct the irregular curvature of the cornea.
- Contact Lenses: Toric contact lenses are designed specifically for astigmatism.
- Laser Eye Surgery: Procedures like LASIK can reshape the cornea, providing a long-term solution to astigmatism.
The Eye Doctor might also prescribe vision therapy as part of the treatment
Once the doctor corrects the underlaying cause of your problem with any above mentioned methods, the specialist might also prescribe visual therapy to help strengthening your 3D vision.
