LEARN ABOUT SINGLE VISION LENSES
The first wearable single vision lens is said to have been developed in Italy in the 13th century. Using the bridge of the nose the glasses would perch in the pince-nez style pinching the wearers nose to keep them in place, or the user would hold them up in front of their eyes to see clearly.
Most individuals who find they need vision enhancement start out by being prescribed a single vison lens. Single vision is prescribed to help individuals with just one aspect of their vison. Near OR Distance. You may hear your eye care professional say you have a refractive error. What they mean by that, is that the shape of your eye is bending light is such a way it is causing blurry vision up close or far away. The refractive error also can cause you to see halos, have migraines, double vision, eye soreness or fatigue.
A single vison lens will have the focus evenly distributed throughout the entire lens and corrects nearsightedness, or not being able to see clearly at a distance, or farsightedness where you need a near correction to see up close.
Lens for farsighted people will be thicker in the center whereas nearsightedness lens will be thicker toward the edges. When your nearsightedness and farsightedness start to affect both of your eyes, your eye care professional may prescribe a multifocal lens aka progressive, bifocal, or trifocal lens to help with correction.
