If you are nearsighted or have “myopia”, then you should get the right pair of glasses for your eyes. If you are not sure about the type of glasses you may need, then let your eye specialist examine your eyes and with the help of his prescription you can have the appropriate glasses to fulfill your needs.
Currently, there are different types of glasses available for different kinds of vision deficiencies. For example, single vision eyeglasses are suitable for viewing distant objects. Single vision is also suitable for driving.
Bifocal glasses consist of multi-purpose glasses. There is a thin line between upper and lower part of the lens. The upper part of the lens is made for distance correction and the lower part helps in reading. This combination helps those people who face difficulty in reading and looking at objects from a distance. Initially, people face some problems in adjusting their sight with these eyeglasses, but later they get use to it.
Progressive lens glasses are like Bifocal lens, but they give better results in intermediate vision, such as finding something on your study table or looking at the dashboard of your car. Interestingly, there is no line between the two lenses, only the user can feel the difference. Users of these glasses also require some time to feel comfortable.
Accommodating with single vision and bifocal lens becomes difficult for many nearsighted computer users. Computer screen creates more difficulties for nearsighted people because they require shifting their distance from the screen. In this scenario a special set of bifocals is prescribed to overcome such vision problem.
