If you find yourself in the position of having your vision prescription fine-tune, you can have your favorite eyecare store or online store have your current optical information placed on file. It is even possible to have your vision prescription placed into an existent pair of glasses. However, some people find that they prefer having an entirely new pair of prescription glasses. New glasses are designed and then custom fitted right on site so there’s little to no wait time. Costs can also be one of the many gains of having your prescription lenses replaced as opposed to purchasing a new pair of prescription glasses. If you are in the market for saving money then the lens replacement is a more than viable option.

Progressive lenses are also called no-line bifocals. These no-line bifocals are in reality trifocal lenses, just without the visible lines. Prescription glasses made with progressive lenses were produced because many people desired to have the convenience of not having to change their prescription glasses in order to read, but they did not want others to notice the visible line either. Progressive lenses have other benefits as well. With progressive lenses, or no-line bifocals, you feel a smooth transition when you move your eyes from objects in the distance to objects close up. With a lined bifocal, the transition between the two different viewing areas can be noticeable and somewhat jarring.
