Top 11 Prism Glasses for Double Vision

Living with double vision poses daily challenges, affecting the quality of life for many individuals. A 10-year population-based study spanning from 2003-2012 discovered that an estimated 850,000 visits to doctor's offices and emergency departments occur each year in the US for double vision. While life-threatening diagnoses are rare, the impact on daily life is substantial.

For those seeking a solution, traditional eyeglasses often fall short. One of the treatments for double vision involves incorporating prismatic power into eyeglasses. Prism glasses, however, lead to thick and heavy lenses, causing discomfort when worn.

To address this common issue, this article aims to guide readers in discovering the best options for prism glasses. These options not only correct double vision but also offer comfort, style, and a renewed sense of visual clarity, enhancing the overall eyewear experience.

How Prism Glasses Correct Double Vision

In normal vision, both eyes collaborate to perceive a single image by receiving light on the same part of the retina. However, double vision occurs when light strikes different areas of each eye's retina, disrupting the proper coordination between the eyes. This affects how the brain processes visual information, resulting in the perception of two separate images instead of one clear picture.

Prism eyeglasses work by bending and redirecting light before it reaches the eyes. This redirection ensures that the light lands on the appropriate part of the retina in each eye, allowing the eyes to work together more effectively. Afterward, the brain smoothly combines the two images into a unified and clear picture.

The prisms are typically incorporated into the lenses of the eyeglasses, and their specific orientation and power are determined based on the individual's eye misalignment.

Two Main Types of Prism Lenses

There are two kinds of prism glasses for double vision. Explore each one in detail below.

Fresnel (Press-on) Prism

Fresnel prisms are made from thin, transparent plastic sheets. These sheets have multiple angled grooves on one side, creating a prism-like effect. The arrangement is such that each prism is connected to the next one, forming a continuous structure.

Fresnel serves as a temporary prism adhesive, and its cost varies from $250 to $500. This is suitable for patients who are uncertain about the effectiveness of prism correction and wish to experiment first. It is beneficial when double vision stems from conditions like diabetes or hypertension.

In a study involving 141 patients prescribed Fresnel prisms, 80% experienced relief from double vision, indicating a successful outcome.

Ground-In Prism

Prismatic strength can be incorporated into eyeglasses to enhance image quality. However, this addition raises costs ranging from $600 to over $1,500, depending on the prescription needs.

Ground-in prisms provide a clearer image than Fresnel prisms, making the glasses resemble typical eyewear. However, they may carry some extra weight and have a thicker edge.

In a study involving 83 patients who were given prisms to address double vision caused by fourth nerve palsy, 92.8% received permanent ground-in prisms, while initially, 38 patients were prescribed Fresnel prisms. Of these, 32 eventually switched to ground-in prisms, and 6 continued with Fresnel prisms.

The satisfaction rate with prism use was 92%. Moreover, over a follow-up period ranging from 2 months to more than 6 years, 86% of the patients continued using prisms.

Prescriptions for Prism Glasses

Unlike standard eyeglasses, prism glasses require a more detailed assessment of vision and eye alignment. During the exam, the ophthalmologist may employ various tests to evaluate the need for prism correction. This may include:

• Hirschberg Test: An examination to check for strabismus, a condition where the eyes are misaligned. Using a pen light, the doctor observes the reflection in the eyes. If the reflection appears off-center, it may indicate strabismus.
• Krimsky Test: This test measures the degree of misalignment by using prisms. While focusing on a pen light, prisms of different strengths are introduced. The correct prism is determined when the reflection in each eye is brought to the center.
• Cover Tests: Cover tests come in three types. The cover/uncover test involves covering one eye and observing any movement in the uncovered eye. The prism and alternate cover test uses prisms and alternating covers to measure the offset between the eyes. The Maddox Rod test determines the type of double vision by assessing the offset between vertical or horizontal lines seen by each eye.

If a prism correction is necessary, the doctor will incorporate it into the patient’s prescription.

If you suspect eye misalignment or experience double vision, consult an ophthalmologist to undergo the necessary tests and obtain a prism prescription that addresses your unique visual challenges.

Top 10 Eyeglass Frames for Prism Lenses

When using fresnel prisms, the choice of frame style is not particularly crucial. However, in the case of ground-in prisms, patients should take frame style into consideration, as lenses with prismatic power can become noticeably thick.

According to the Review of Optometry, when prescribed with a ground-in prism, opting for high-index lenses, plastic frames, and smaller-sized frames can significantly enhance the weight of the lenses. Additionally, applying an anti-reflective coating proves beneficial for individuals wearing prism lenses.

Can prisms in glasses help with lazy eye?

Prisms in glasses can be beneficial for certain cases of lazy eye (amblyopia) associated with strabismus. By incorporating prisms into the eyeglass prescription, the eyes can be aligned more effectively, which may aid in reducing the impact of lazy eye. However, the effectiveness of prisms in treating lazy eyes depends on the specific condition, and consultation with an eye care professional is crucial to determine the most suitable treatment approach. Prisms may be used in conjunction with other interventions recommended by an eye care specialist for a comprehensive treatment plan tailored to individual needs.

Can you have progressive lenses with prism correction?

Yes. Prism correction can be incorporated into any type of lens, whether it's single-vision, bifocal, or progressive. Progressive lenses with prism correction are viable for individuals with presbyopia or multifocal needs.

Are there alternatives to prism glasses?

Yes. In addition to prism glasses, alternative treatments for double vision include Vision Therapy, Surgery, and Botox. The choice of treatment depends on factors such as the underlying cause and individual preferences, and each alternative provides distinct approaches to managing double vision.

Do prism glasses cause side effects?

Adjusting to new prism glasses or an updated prescription may take a few days, during which some eye strain is normal. Rare side effects include headaches, nausea, and eye pain. If any of these symptoms occur, it's advisable to contact the eye care professional who prescribed the glasses. Refitting the frame or obtaining a new prescription may be necessary.
