The set of trial lenses is intended for examination of visual deviations: myopia, hypermetropia, astigmatism and presbyopia for the examination of strabismus and color blindness. By placing various lenses in a trial universal frame, optimal correction of the patient's vision is achieved. This kit is used for testing myopia, hyperopia, strabismus, achromatopsia, etc.

Spheres:

The curved surface forms part of a spherical lens and the diopter is the same at all axis positions.
After passing through the lens, the light beam is focused at a single point (or virtual focus).
The spherical lens includes concave (-) and convex (+) lenses, which are used to examine the eye's myopic refraction, hypermetropia, and presbyopia.

Occluder:

This is a kind of opaque lens to cover the non-examined eye tested in a dark room.

Matted lens:

This is a type of translucent cover lens and is used for infants or outdoors as an occluder.

Cylinders:

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

Slit:

There is a slit in the center through which the light beam can pass, while it cannot pass through the other part of the lens.
By rotating this lens in front of the eye, astigmatism can be examined because your vision changes for better or worse at a certain axis position, and vice versa, you can prove the absence of astigmatism if your vision has not changed.

Lens with a flat field of view:

This is a kind of transparent flat lens and the light beam never bends as it passes through the lens. It is used to test for false blindness.

Cross Cylinder:

This is a kind of lens with opposite diopter positions in two axes, and is used to examine the level and axis position of a cylindrical lens to determine astigmatism.
When using, place the cross-cylindrical lens in front of the cylindrical lens and make the position of one axis coincide with the position of the axis of the cylindrical lens, then rotate the cross-cylindrical lens 90° counterclockwise and observe the change in the patient's vision, and if his vision does not change , then the angle in degrees of the lens used would have to be adjusted according to different results.
When adjusting the axle position, respectively place the two axles of the cross-cylindrical lens on the right (45°) and left side (45°) of the primary test cylinder lens axle, then turn it counterclockwise and see the difference in vision in the two positions.
If vision at one position is better than vision at another position, the axis of the cylindrical lens can be rotated slightly towards the mark of the best position, then the same examination should be carried out again until the differences in vision at the two positions can hardly be distinguished from each other, which will prove that the cylindrical lens is in the correct position.

Maddox:

It has a single row of rods on its surface that determine the direction where the light can go and then bend it into a line in the direction perpendicular to the glass rods.

Pin Hole:

There is a small hole in the center through which a light beam passes, forming an artificial pupil, and it is used to improve the diopter, especially in astigmatism, after wearing it for a while.

Color Lens:

This type of lens comes in a variety of colors: red, green, blue, yellow, and dark brown and is used to test color perception.
For a person whose diopter image is cloudy (for example, a cataract patient), a red or green lens is appropriate; it can also be used for re-examination and examination of color blindness.

Special attention should be paid to a group of trial spectacle lenses containing 42 elements with a plastic handle used for the examination of myopia, hyperopia, etc.

The tangent plane of a prismatic lens shows a wedge-shaped sign. After passing through the lens, the light beam bends towards the bottom, and the object moves to the edges. This kind of lens is used for examining the eye-body, tilt and invisible tilt, as well as for training the eye-body.
