People who have their eyes working simultaneously; in technical words, they have great binocular vision are extremely lucky. Those who have a misalignment of eyes face an imbalance in their eye muscle, leading to people who have trouble focusing or having double vision.
Causes of diplopia:
Double vision is referred to as “diplopia.” This term is a medical condition in which a person can see images that overlap or two separate images in either eye or both. The most frequently occurring cause of diplopia (double vision) is strabismus.
Strabismus is a condition that refers to the misalignment of eyes. Each person has the movement of their eyes controlled by 6 eye muscles. To focus on one object, these eye muscles have to work in line with the opposite eye.
When they do not coordinate correctly, strabismus occurs. 4% of Americans have strabismus, stated by the Pediatric Ophthalmology by American association. When this happens, you are likely to experience one of the symptoms:
- Alignment of eyes not being correct
- Tiredness in the eyes
- Vision can also be decreased.
- Double vision
Your brain's ability to create one 3D image but put together the two images your eyes see is damaged by strabismus. Due to that, both eyes see different images.
Fix double vision with prism correction
Prism correction is by far the most effective and commonly practiced method to fix double vision. When prisms are put inside lenses for correction, they are also part of the lens material. As a patient for you, there might be no difference physically in your lens, but the brain starts to function in a way that the shift in the image created by the prism is fused into one coherent image, and the brain processes that.
Other than this, therapy of the vision can be seen as another form of treatment. In this, you are made to do eye exercises to improve the eyes' focus and misalignment. Prisms are used here as well in eyeglasses made for these exercises. When the latter methods do not work, eye surgery is the last option for binocular vision difficulties.
How to detect if you need prism correction?
If double visions and focus issues occur even after you wear regular glasses, then the imbalance caused in the phobia muscle must be the reason for strain in the eyes. Trying to read small text or being in contact with a computer screen for 24 hours then that can make these conditions worse. Your vision needs to be safe from HEV blue light; hence blocker blue lenses are the best option for you, and you need to ask your eye doctor about prism lenses.
Suppose you have prescribed eyesight glasses with prism correction. In that case, if you take a look at your prescription, you will find a triangle and subsequently a numerical measurement along with an indicator about direction. Hence people with double vision can benefit from prism correction.
