Headaches can either be triggered by various triggers or be a result of
single or various combined conditions. Find out what is the cause behind
your headache. Herein I am taking up two major causes of headache- light
sensitivity and eye strain.
Light sensitivity
It is usually
the migraine patients, who are most sensitive to light and in whom
glaring lights might trigger headaches. Especially slow "flickering"
lights rather than rapidly flickering ones might lead to a headache.
This
dazzling, flickering light can be found in conditions where light is
reflected, for example, snow, sand, water or through clouds. It is the
same effect that is experienced when you are sitting in front of a
television or a cinema screen. Fluorescent and blue wavelengths of light
are also considered to be harmful, especially for young children. It is
always better to use anti-glare screens on computers as well as on
televisions.
In fact, migraine patients who are extra sensitive
to bright light are advised to sit in a dark room while they are
suffering from an attack of migraine.
Eyestrain
It is
quite common to see people complaining of headaches because of
eyestrain. It might be true that certain activities might lead to
refractory errors in the eye thus leading to eyestrain and consequently
to headaches.
The conditions which put a strain on the eyes can
be sitting in front of the computer or television for too long, playing
video games, or, reading in improper lighting conditions. But apart from
these, a poor posture, stress, and long periods of concentration are
also causes for headaches.
