Attachment of Fresnel prism sheet onto the spectacle lens. First, the spectacles and the Fresnel prisms are washed with a gentle liquid detergent to clean grease or soil. Then submerge the spectacles and Fresnel prism in a large cup full of lukewarm water. Clean small air bubbles clinging to the surface. Position the Fresnel prism with a smooth side towards the inner layer of the spectacle lens with water. The final adjustments can be made by pushing the Fresnel prism and pressing it dry. The edges of the Fresnel prisms should be inspected to rule out any overlapping over the spectacle frames. Remove and reapply if any dust particles or air bubbles are noticed.[27]

Fresnel prisms are used to relieve diplopia. These can be used in fourth and sixth nerve palsies, restrictive motility secondary to thyroid-related orbitopathy, and convergence insufficiency. Only some patients better accept these in comparison to conventional prisms. These are also used in patients temporarily before surgery. This helps confirm the deviation in prism dioptres and better surgical planning. After surgery, Fresnel prisms play an essential role in avoiding postoperative diplopia.[29]

Patients who complain of double vision need a detailed squint evaluation. Clear history regarding onset, duration, progression, diurnal variation, and prior episode of trauma/ fever/ association with underlying systemic disease needs to be explored. An interprofessional collaborative approach involving orthoptists, optometrists, ophthalmologists, and physicians is required. A strabismologist or neuro-ophthalmologist opinion should be sought whenever needed.[29]

The Fresnel prism trial sets are an indispensable tool for evaluating ocular motility. These prisms allow for the accurate evaluation of large angle deviations. The Fresnel prisms are available as rigid and loose stick-on prisms.[21] The flexible prism membrane is made from optical-grade polyvinyl chloride (PVC). Any patient presenting with a squint or double vision needs to be thoroughly evaluated. The ophthalmic instruments required would include a loose Fresnel prism, binocular single vision charts, diplopia charting, Hess charting, and Goldman perimetry for testing the binocular field.[8]

Some of these patients might have underlying uncontrolled diabetes or hypertension, which needs urgent intervention and be life-threatening to the patient. Interprofessional coordination between physicians, orthoptists, nurses, and ophthalmologists, including squint or neuro-ophthalmologists, ensures better management and helps the patient make better decisions. Once underlying causes have been ruled out, dispensing Fresnel prisms requires coordination between strabismologist and orthoptists.[21]

Initially, they were intended for use in lighthouse beacons. Prisms have been used extensively in the field of ophthalmology, especially related to neuro-ophthalmology and strabismus.[3] Prisms are used extensively to increase the binocular field, relieve diplopia, or expand the field of vision. Fresnel prisms are thin transparent plastic membranes with multiple tiny prisms attached from base to base. Augustin Fresnel articulated the optics of Fresnel prisms.[4]

The embedded vision market continues to grow strongly. One aspect of this success is based on technical advancements that expand the spectrum of possible applications.

After 1960, the Fresnel principle, which existed for more than 150 years, was used for the first time to manage strabismus. In 1970, the optical scientific group from San Rafael of California designed a combination of a series of Fresnel press on prisms.[1] These prisms are made up of plastic membranes with powers ranging from 0.5-30 prism dioptres. The Fresnel prism is derived from the concept of hand-ground lenses prepared by the physics and French specialist Augustine Fresnel in 1921.[2]

Spectacle lens out of frame – The Fresnel prism is cut with the scissors as close as possible to the size of the carrier lens. The optical flush is trimmed along the beveled edge of the spectacle lens with the help of a razor blade. This is then inserted into the spectacle frame.[2]

The Fresnel prisms can be prescribed permanently or temporarily based on the underlying indications. The most common personnel involved are either orthoptists or ophthalmologists.[21] Optometrists can also prescribe Fresnel prisms after due consultation with an ophthalmologist. The formula for prescribing Fresnel prisms is essential while prescribing these prisms. Prism dioptres of Fresnel prism = 2/3 (phoria) – 1/3 (compensating fusional vergence). If the patient has an exophoria of 9D and a base out prism of 6D is needed to blur, the prism power required would be 2/3(9) – 1/3(6). Thus, this patient would need four D dioptres base in prism to avoid diplopia in exophoria patients.[8]

The flexible prism sheet is thinner than 1mm in thickness. The prism is cut in the spectacle glass's shape and stuck to it.[24] A prism adaptation test should be done before prescribing Fresnel prism. The prism is cut such that it is smaller than the spectacle lens, which is about 1mm inside the spectacle edge. It is essential to take care that the prism membrane should not overlap the spectacle lens edge or the frame, as this may allow air bubbles to be trapped between the prism and the spectacle lens.[25]

Deterioration of visual acuity due to reflections is common with prisms greater than ten prism dioptres. The vision deterioration with Fresnel prisms is more than with conventional prisms. A 30-prism dioptre conventional prism might reduce visual acuity from 20/20 to 20/30. This is lesser than the Fresnel prism, which reduces visual acuity from 20/20 to 20/100.[8]

It is essential to check the optical center of the Fresnel lens with that of the carrier lens. The smooth surface of the Fresnel prism is placed facing the inside surface of the spectacles. These are available from powers ranging from 0.5 prism dioptres to 30 prism dioptres.[23]

The angle of refraction of a prism depends upon the angle of the surface and the refractive index of the material of which the prism is made.[5] The angle of refraction is independent of the thickness of the prism. These offer the advantage of being lightweight and easy to handle. The most common use is to temporarily relieve the diplopia in cases like nerve palsies secondary to trauma, blowout fractures, decompensated phoria, divergence insufficiency, or convergence insufficiency.[6]

Flanders et al. shared their clinical experience among 141 patients prescribed Fresnel prisms. They reported that 90% of 127 patients received Fresnel prisms over the non-dominant eye. Of the patients, 80% had a successful outcome, with relief of double vision. There was a dropout of 6%; eight patients discontinued prism because of decreased vision with prisms, persistent double vision, torsion, or optical aberrations.[29]

A prism is a wedge-shaped glass piece made up of transparent material. They have the property of a light ray's deflection towards the base. Prisms are routinely used in orthoptic practice to assess the degree of squint and manage deviations so that the eye becomes orthotropic. Prisms have been used in ophthalmology to treat binocular pathologies for over 100 years. However, only after the 1950s did instrumental orthoptics not provide the desired results; pediatric ophthalmologists started using prismotherapy as a prime treatment modality. As new prisms became available, the old conventional ones with high powers were aborted. After 1960, the Fresnel principle, which existed for more than 150 years, was used for the first time to manage strabismus. Fresnel prisms are made up of plastic sheet, which is thin and transparent, and it induces a prismatic effect. One side of the prism has angular grooves, and the other smooth side is attached to the lenses of the glass. This activity will describe the anatomy and physiology, indications, contraindications, equipment, preparation, technique, complications, and clinical significance of Fresnel prisms.

Fresnel prisms are made from a thin transparent plastic sheet consisting of multiple angular grooves on one side. These prisms are much lighter than the regularly used prisms of the same power.[8] It can be thought of as a series of tiny plastic prisms placed on a plastic platform that is thin and adjacent to each other in a format that the base of one is attached to the apex of the next prism. The magnification effect seen with conventional prisms is minimal with Fresnel prisms.[9]
