Depth perception is an essential part of our vision for safety and navigation in our daily environment. It’s the ability to see the world in three dimensions and helps us judge the distance of objects.
Without accurate depth perception we would struggle to do everyday tasks such as driving, walking, or catching a ball.
We’ll discuss how to improve depth perception in our guide below.
Understanding Depth Perception
Depth perception comes in different visual cues such as -
Binocular vision - This is where the slight difference between the images in both eyes allows the brain to calculate depth, this gives a wider field of view.
Monocular cues - With one eye depth can still be perceived through size, texture gradient, motion parallax, and occlusion.
Stereopsis - This is the brain's ability to merge two images from each eye into a single 3D image.
Common Causes Of Poor Depth Perception
Depth perception can be caused by some factors such as -
Amblyopia (lazy eye) - Reduced vision in one eye due to abnormal visual development.
Strabismus - The misalignment of eyes prevents them from focusing at the same point.
Anisometropia - A significant difference in prescription strength between two eyes.
Eye injuries - Trauma that affects eye structure.
Certain medical conditions - Cataracts, glaucoma, and macular degeneration.
Strategies To Improve Depth Perception
If you're experiencing some problems with depth perception then these are some strategies you can try to improve it -
Vision Therapy Exercises
Brock string exercise - Using a string with beads to improve eye coordination, involves focusing on different beads so the string forms an ‘X’ shape.
Barrel card exercise - Focusing on images to enhance convergence and divergence. This is another focus exercise to help bring the eyes together when looking at close objects.
Computer-based training - Software that offers various depth perception activities.
With these vision therapy exercises consistency is key so you can see significant improvements over time.
Corrective Lenses
Prescription glasses - Correcting refractive errors with glasses can balance vision between eyes.
Prism lenses - These lenses adjust the way light enters the eye which can help alignment issues.
Bifocals or progressive - Helps in cases of presbyopia (age-related focus issues).
At GlassesShop we stock all these kinds of corrective lenses and have various promotions going on such as gettingyour first pair free, clearance sales, coupon codes, buy one get one free deals, and glasses under $20.
Technological Aids
Virtual Reality (VR) training - VR environments can help stimulate depth and improve stereopsis.
Augmented Reality (AR) apps - These help to provide exercises for vision improvement.
Assistive Devices - Gadgets that help enhance visual cues for those with severe impairments.
Tips For Helping Depth Perception In Daily Life
Proper lighting - These ensure environments are well-lit to enhance visual cues.
Reduce screen time - Excessive screen usage can strain the eyes, taking regular breaks can help this.
Healthy diet - Nutrients such as vitamins A, C, and E help eye health, you read more about the best foods for your eye health here.
Regular eye exams - The early detection of vision issues can help stop worsening issues.
