Special designed visual aid for prebyopes solving bifocal spectacle induced walking problem comprises a special type of spectacle where extra lenses are used as per need of a presbyope through an improved mechanical means where proper dispensing methods are followed. A person wearing bifocal spectacle feels blurring of vision near the foot which causes problem in smooth walking. This is due to the additional power for near vision. To solve this problem, a separate piece of rimless lens having the additional power for near vision is placed just in front and inferonasal portion of each of the lens for distant vision of a spectacle by a mechanical means, revealing no unwanted prismatic effect, when doing near work. So a person can see both distant and near objects clearly with the visual aid, like conventional bifocal. Then each of the said separate pieces of rimless lens is swiveled from its position to another position by the said mechanical means where it does not causes visual problem when walking. So the person uses only the lens for distant vision in the time of walking without problem.
