Seeing two images of a single object can be more than just disorienting. It can also be debilitating, disrupting daily life and making even simple tasks difficult. It may also signal an underlying health problem that needs attention. Fortunately, for many, a clear and effective solution exists, and that is prism eyeglasses. These specialised lenses can correct your vision and restore your quality of life.
What Is Double Vision
Normally, your eyes work in perfect coordination, each sending a slightly different image to your brain. Your brain then fuses these two images into a single, three-dimensional picture. Double vision occurs when this coordination breaks down. The eyes become misaligned, causing them to send two distinctly different images to the brain, which cannot merge them.
The causes are varied and can include:
Eye muscle problems:
Certain conditions, such as strabismus, commonly known as crossed eyes, myasthenia gravis, or Graves’ disease, can cause the eye muscles to work unevenly. When this happens, the eyes struggle to move together smoothly, leading to misalignment and double vision. Addressing the underlying muscle issue often requires both medical care and specialised lenses, such as prisms.
Neurological issues:
Double vision can also result from neurological conditions, including stroke, migraines, or traumatic head injuries. These issues interfere with how the brain processes signals from the eyes, making it difficult to merge two images into one. For many individuals, prism glasses can provide stability and clarity during recovery.
Nerve problems:
Diseases such as diabetes or multiple sclerosis may damage the delicate nerves that control eye movement. When these nerves are weakened, the eyes can drift out of alignment, causing persistent double vision. Prism correction helps realign the images, giving the person a clearer and more comfortable visual experience.
How Prism Glasses Fix Double Vision?
Prism eyeglass lenses are crafted with a wedge-shaped design that bends light before it enters your eye. This optical trickery effectively redirects the light rays from an object, shifting the image onto the correct part of the retina (the light-sensitive layer at the back of your eye). When both eyes are open, this realignment allows the brain to receive two images that it can successfully fuse into one clear, single picture.
Getting a Prism Prescription: The process
An accurate prism prescription requires a comprehensive, in-person eye exam. Self-diagnosis or using pre-made readers is not an option. Your optometrist or ophthalmologist will perform specialised tests to measure the exact degree of misalignment. These tests ensure your prism spectacles lenses are precisely tailored to your unique needs.
- Hirschberg Test: Shining a light to observe its reflection on the cornea.
- Krimsky Test: Using prisms of different strengths alongside a light to measure deviation.
- Cover Tests: Covering and uncovering each eye to see how it moves to focus.
- Maddox Rod Test: Using a red lens to measure vertical and horizontal alignment.
Understanding a Prism Prescription
Your prescription will include two key pieces of information for the prism:
- Prism Diopter (P.D.): This indicates the strength of the prism needed to correct the misalignment.
- Base Direction: This tells the optician which way the thickest part of the prism should be oriented, Base In (BI), Base Out (BO), Base Up (BU), or Base Down (BD). This direction is crucial for correcting your specific type of double vision.
This combination allows opticians to design prism eyeglasses that align the eyes correctly and help reduce or eliminate double vision.
Prism Lens Options for Double Vision Correction
When it comes to correcting eye misalignment and double vision, prism glasses offer an effective solution. These specialised lenses redirect light to help the eyes work together, reducing strain and restoring comfortable vision.
People often refer to them as double vision glasses because of their ability to merge two images into one clear view. There are two primary types of prism eyeglass lenses:
Fresnel Prism Lenses:
A thin, vinyl sheet is pressed onto your existing eyeglass lens. This is often a temporary solution as it is slightly visible and can reduce clarity, but it allows for easy adjustment of prism strength.
Ground-In Prism Lenses:
The prism power is permanently incorporated into the lens itself during manufacturing. This provides the clearest, most aesthetic vision and is the recommended solution for long-term use.
Do Prism Eyeglasses Cause Side Effects?
Some minor side effects of wearing prism glasses are normal. An adjustment period is normal when you first start wearing prism glasses. Some people experience mild eye strain, headaches, or dizziness as their brain adapts to the new way of processing visual information. These symptoms typically subside within a week or two.
However, if you experience severe headaches, eye pain, or persistent double vision, you should contact your eye care professional immediately, as your prescription may need fine-tuning.
