When young individuals wear glasses or contacts, most of them do so because their distance vision requires correction. Some may be prescribed reading glasses for near vision. As we age, more of us require eyeglass prescriptions for near vision or we buy cheap generic reading glasses without prescription.
Most bifocals prescribed for individuals beyond the age of 40 — often prescribed because they’ve developed presbyopia — correct far and near vision. Yet these glasses do not provide an appropriate lens for the distance and eye activity involved in computer work. Some people believe trifocals and progressive lenses — both of which provide a portion of lense for intermediate distance vision — can be utilized for computer work. However, these lenses don’t provide nearly enough surface space to ease and protect eyes for extended periods of computer use.
Many computer users will suffer headaches, eye strain and blurried vision if they do not utilize appropriate computer glasses. Such symptoms indicate computer vision syndrome. These problems compound themselves with further issues when computer users without computer glasses attempt to adjust for their strained eyes or blurry vision by tilting their head to view the monitor through the bottom of their glasses or by excessively leaning towards the monitor. Such behavior leads to sore back, shoulders and neck problems.
