When you're not sure whether to choose single vision or progressive lenses, visit an optician for an eye vision exam, where the optometrist will perform a series of tests on your eyes, including a visual acuity exam, eye movement tests, and adjustment tests for nearsightedness and farsightedness. These tests will help determine the type and extent of your vision problems, as well as whether or not you need correction for multiple focus ranges.

Review the prescription carefully:
The optometrist will examine your vision needs and provide a prescription for lenses that are appropriate for you.

No refractive power (ADD):
If the absence of refractive power (ADD) in your optometrist's prescription, which means that you only need correction for one field of vision range (one of near, intermediate, or distance), then single vision lenses may be the right choice for you. Single vision lenses are capable of meeting specific vision range needs, such as distance, intermediate or near vision (presbyopia).


With addition (ADD):
If your optometrist's prescription includes addition (ADD), it means that you need correction for more than one range of vision distances, such as close reading and mid-distance work. In this case, progressive lenses may be a better choice. Progressive lenses have a gradual degree change that allows correction of near, intermediate, and distance vision, without having to switch between multiple pairs of eyeglasses.

Above is to check if the refractive power (ADD) is present on the lens prescription form, let's know more about the difference between single vision lenses, bifocal lenses, and progressive lenses:


Single vision lenses
Single vision lenses are prescription lenses that have only one use, for standard eyeglass prescriptions. They are intended for one field of view across the entire lens to correct for a particular field of view (near, intermediate, or far), such as: looking at distant objects, looking at intermediate objects such as computers or telephones, or looking at near objects for reading (presbyopia).


Bifocal Lenses
Bifocal lenses have two different focal areas for correction of distance and near vision. Bifocal lenses may be an option if we are facing presbyopia (old eyesight) problems and only need to correct distance and near vision and have no other special needs.

Trifocal Lenses:
Trifocal prescription lenses contain three distinct optical zones, which are used to correct vision problems at different distances. These lenses usually consist of a near, intermediate, and distance zone, each with a different optical power, and are designed for the convenience of those who need to correct near, intermediate, and distance vision at the same time.
When you're not sure whether to choose single vision or progressive lenses, visit an optician for an eye vision exam, where the optometrist will perform a series of tests on your eyes, including a visual acuity exam, eye movement tests, and adjustment tests for nearsightedness and farsightedness. These tests will help determine the type and extent of your vision problems, as well as whether or not you need correction for multiple focus ranges.
Progressive Lenses
Progressive lenses are multifocal prescription lenses that provide correction of near, intermediate, and distance vision problems simultaneously, providing a smooth transition vertically from the top of the lens (for distance vision) to the middle of the lens (for intermediate distance) to the bottom of the lens (for near vision) , without any obvious dividing lines or jumps, providing the wearer with a more natural, continuous visual transition, and thus, providing a more convenient and comfortable visual Experience.


Non prescription lenses
Non-prescription lenses are lenses that do not have any optical or vision correction prescription. They have no prescription for nearsightedness, farsightedness, or astigmatism, and provide only clear lenses, for eye protection or as a fashionable eyewear option.
