Spheres
The curved surface forms a part of the spherical lens and the dioptric power on all axis positions is the same. After passing through the lens, the light beam focuses on one point (or a virtual focus). Spherical lenses includes concave lenses (-) and convex lenses (+), which are used to examine myopia, hyperopia and presbyopia.

Cylinders
The curved surface forms a part of the cylindrical lens and the dioptric power on all axis positions is not the same. After passing through the lens, the light beam focuses into a straight line (or a broken line). Cylindrical lenses consists of concave cylindrical lenses and convex cylindrical lenses that are used to examine astigmatism.

Prisms
The tangent plane of a prismatic lens is wedge shaped. After passing the lens, the light beam bends to the bottom and the object shifts to the edges. This kind of lens is used to test the ocular muscle, slant and invisible slant as well as to train the ocular muscle.

Occluder
This is a kind of opaque lens for covering the uninspected eye of the examinee in a dark room.

Frosted Lens
This is a kind of semi-transparent cover lens and mainly used for babies or used outside of the room as an occluder.

Slit
In its center there is a slit, through which light can pass while it can not pass through any other part of the lens. By turning this lens in front of the eye, astigmatism can be examined as vision changes for better or worse at a certain axis position, on the other hand, it proves no existence of astigmatism if vision does not change.

Plano lens
This is a kind of transparent plain lens and the light never bends when it passes through the lens.
It is used to examine false blindness.

Color Lens
These lenses include different colors: red, green, blue, yellow and dark brown and are used to examine color sensitivity. For patients whose dioptric image is muddy (e.g a patient with cataract), the red or green lens is suitable. It also can be used for re-inspection and examination of color blindness.

Maddox
On its surface, there is one row of bars through which a spot of light can pass, and then bends into a line to the direction, which is perpendicular to the glass bars.

Pin hole
In its center, there is a small hole, through which a light beam passes to form an artificial pupil.
It is used to improve diopter especially the astigmatism after wearing it.

The Luxvision TL-232 Trial Lenses Set features 232 reduced-aperture glass lens pieces with plus and minus cylinders secured in plastic rings. This trial lens kit comes in a leather case with removable tray, diopter indicators, and dual combination locks for security. Wide ranging sphere and cylinder powers as well as a variety of accessory lenses will allow you to perform better vision testing. This classic form of refraction enhances prescription accuracy for low vision patients in particular, offering accurate vertex distance, which is very helpful for high refractive error patients. Similarly, any patient who relies on eccentric viewing and needs to move their eyes or head to see around a scotoma can greatly benefit from trial frame refracting. * Trial Frame not Included
