I feel blessed when I think of Cheap Glasses 123. Bi-focal lenses are very helpful lenses that contain two prescriptions. The top part of the lens is employed for your distance image and the bottom part is used for reading that requires enough of clear vision. There is a line that clearly separates distance and reading sections that is peculiar of them. Bifocals have two corrective lenses on each side of a pair of glasses, on top for far away and a different prescription on the bottom for near. Bifocals are a type of prescription glasses designed for people who require both near and farsighted vision correction. When I used Bifocals for the first time I suffered persistent headaches and even dizziness at many times. Getting adapted to the small coverage of view offered by the reading segment of bifocals took me some time but then I learnt to move my head or the reading material rather than the eyes that I earlier used to. When using Computer monitors that are generally placed directly in front of users and can lead to muscle fatigue due to the unusual angle and constant movement of the head that eventually affects our eyes.
There are normally three ranges of vision. The near range is for reading and seeing up close objects. The mid-range is for seeing things not more than at an arm’s length. The distance range is anything farther away like road signs, traffic lights, anything at the distance.
