What is a Prism Lens?
A prism lens is an optical component that bends or redirects light using refraction. Unlike regular lenses that focus light, prisms change its direction, making them useful in photography, ophthalmology, and scientific optics.
How Do Prism Lenses Work?
Prisms alter the path of light through angled surfaces and varying thickness. This effect is used to:
- Split or combine light beams
- Shift images laterally
- Correct eye alignment
- Create artistic light distortions in photography

Prism Lens Photography: Create Dreamlike Visuals
In creative photography, lens prism filters or photography prisms are handheld glass or acrylic elements placed in front of the lens. They bend incoming light to create stunning refractions, rainbow effects, and reflections.
Common Uses in Photography:
- Light streaks and flare effects
- Surreal portraits
- Reflection mirroring
- Kaleidoscope-like visuals

Prisms in Optical Lenses: Technical Applications
Prisms are widely used in scientific, medical, and industrial optics. At Bote Singapore, we manufacture high-precision optical prism lenses including:
| Type of Prism | Function | Application |
|---|---|---|
| Right Angle Prism | Reflects light 90° or 180° | Beam steering, laser systems |
| Dove Prism | Image rotation | Astronomical optics |
| Wedge Prism | Light deviation without distortion | Beam alignment, interferometers |
| Penta Prism | 90° image redirection, independent of tilt | Surveying equipment |
| Roof Prism | Inverts and reverses images | Binoculars, imaging optics |
| Dispersive Prism | Separates light into spectrum | Spectroscopy |
Types of Prism Lenses in Ophthalmology
In ophthalmology, prismatic lenses are used to correct binocular vision problems like strabismus (eye misalignment) or diplopia (double vision).
Key Prism Lens Types for Eye Care:
| Prism Lens Type | Use Case | Description |
|---|---|---|
| Fresnel Prism | Temporary correction | Thin, stick-on flexible plastic lens |
| Ground-in Prism | Permanent correction | Built into eyeglass lenses |
| Base-In/Base-Out | For converging/diverging eyes | Moves images inward or outward |
| Vertical Prism | For vertical misalignment | Shifts image up/down |
