A healthy vision has become the first casualty of a fast paced lifestyle. Most people don't pay much attention to the importance of a fulfilling diet, much-needed rest and regular exercise. This inevitably leads to deteriorating eyesight. Generally, when a person develops a vision disorder its either myopia (where the person is unable to view objects at a distance) or hyperopia (where it becomes for the person to look at nearby objects). Both of these vision problems can be cured using a pair of single focal lenses. But with increasing age, irrespective of your habits, almost every person develops traces of presbyopia. If a person unfortunately has another vision problem, aside from presbyopia, then he/she will require a pair of glasses which have varifocal lenses.

There are different kinds of varifocal lenses, based on the attributes and designs, the most common of them being, the standard varifocal lenses. These lenses are pretty inexpensive and although their price is a little more than the regular bifocal or trifocal lenses, the advantages offered by these varifocal lenses far outweigh the price. Standard varifocal lenses offer a wide reading area but care should be taken while choosing the frame which can allow enough vertical height which can help in a smooth transition from distance vision down to reading.

If you want to add a stylish element to your varifocal glasses, then you should choose the short corridor varifocal lenses that are designed to fit into smaller frames. Due to the short corridor style, the space for reading vision is not too wide, causing distortion when you look outside the corridor. One possible solution is, when looking down to read, look straight ahead and not to the sides. Short corridor varifocal glasses are smaller in nature and thus require skilled opticians to craft it.

Computer varifocal glasses, also known as "office lenses" are fast becoming a popular option with the increasing usage of computers in our daily lives. These varifocal lenses are designed to offer a clear vision at around 16 inches to 6 feet. Apart from using the lenses while sitting in front of a computer, they can also provide vision assistance to dentists, librarians and other professionals who have to spend a lot of time watching things up close.

Premium varifocal lenses are crafted according to the prescription of the user. This gives it a free-form feel offering a clearer vision and a comfortable eyewear experience.
