Using iphones without eye strain
The biggest buzz in the consumer world comes from the newest iphone
or its equivalent.
From the high level professional to the trendy teenager and to even
the tiniest toddler discovering his world, the smartphone has become an
essential part of daily life. The number of hours spent staring at a
touch screen, a computer screen, a tv screen and at all of them
combined, is alarmingly high.
Eye strain is therefore a growing concern, not only for adults but
for many children as well. Eye strain is one of the problems related to
prolonged computer use and has many related symptoms including head
aches, blurry vision, dry eyes, neck and shoulder pain. Often the
problems are temporary and cease after you stop using the computer.
However, it is important to get your eyes tested to ensure that the
problems are not caused by uncorrected visual defects such as
short-sightedness, astigmatism, presbyopia, etc.
These problems can be corrected by wearing ophthalmic lenses. It is
important to understand that viewing a computer, smartphone or other
electronic device with a lit screen does not have the same impact on the
eyes as reading a newspaper or a printed page. Often the letters on the
computer screen are not as precise or sharply defined, the level of
contrast of the letters to the background is reduced, and the presence
of glare and reflections on the screen may make viewing difficult.
Special anti-reflective lenses that cut off the glare and reflection
from a lit screen provide protection and relief to the eyes.
Anti-reflective lenses provide comfort and protection and can be worn
for computer use even if you do not have a vision correction.
Viewing distances and angles used for computer work are also often
different from those commonly used for other reading or writing tasks.
As a result, the eye focusing and eye movement requirements for
computer viewing can place additional demands on the visual system.
Therefore, posture and position are key aspects to reducing eye strain.
Finally, for those who require reading glasses, the best lens for
using computers, iphones and other electronic devices are progressive
lenses which provide sharp vision at all distances.
Multifocal progressive lenses give distance vision, near vision as
well as intermediate vision. |
