Single vision lens :These lenses refer to eyeglasses containing the exact same power, or focal power,
distributed throughout the entire lens (top to bottom) and can be used to correct nearsightedness, farsightedness, astigmatism, or presbyopia.
Most people who wear glasses before the age of 40 have single vision lenses.
If you need to wear glasses for both distance and near vision, you could wear separate pairs of single vision glasses dedicated to each task.
However, the preferable option would be to consider the benefits of Bifocals and Varifocals.
Bifocals lens :Bifocal lenses are comprised of two parts the upper part normally used for distance vision and the lower part used for near-vision, usually a segment line separates the two. Many people after reaching age 45 develop a condition called presbyopia, which is a deterioration in the ability of the eye's natural lens to expand or contract in order to focus on close objects. People with presbyopia need a special lens for reading and may need a different lens for seeing in the distance. Bifocals are used so that you wouldn't need to switch glasses when reading or seeing distant objects. Bifocal eyeglasses use to have a line separating the top and bottom of the lens, so preferable option would be to consider the benefits of Progressive lens.
Progressive lens :A progressive design or multifocal lens provides excellent vision at all distances. The various correction areas partially overlap into each other, so that the discomfort of any sudden transition into each segment is eliminated. Many people who require the use of a bifocal prefer progressive lenses because they give a more youthful appearance and are more functional. The lenses contain no visible line and progressively increase in strength as you move your eyes down the lenses.
Reading glasses :The need to begin wearing reading glasses regularly when reaching age 35 - 40 is due to a condition called farsightedness
in which the lens of the eye loses its ability to focus, making it difficult to see objects up close.
Symptoms: Decreased focusing ability for near objects. Reading glasses provide extra assistance to focus on small objects at close distance,
like words on a page or needlework. It's virtually a universal condition, and unfortunately no refractive surgical procedures can currently correct this disorder,
SO the best recommend option for you could be single vision lenses dedicated to reading prescription or you may be looking for a quick solution to keep handy by using
