ROCHESTER, N.Y. – According to a
global study of vision-corrected subjects surveyed to better understand
eye-related symptoms, halos and glare are common and bothersome
symptoms. Halos are the appearance of rings around sources of light
while glare is the difficulty seeing in the presence of bright light.
The majority of patients who experienced these symptoms reported they
were most likely to experience halos or glare in the evening or late at
night. The symptoms were commonly associated with bright lights,
headlights, being in the dark and nighttime driving.
The Needs, Symptoms,
Incidence, Global Eye Health Trends (NSIGHT) study surveyed 3,800
spectacle- and contact lens-corrected subjects, 15 to 65 years of age,
from seven different countries (China, Korea, Japan, France, Italy,
United Kingdom, United States) to better understand the eye-related
symptoms that vision-corrected patients experience. The NSIGHT data
provided valuable details on how often patients experienced halos and
glare and the degree to which they found them bothersome.
NSIGHT Study Highlights:
- About half of the spectacle and contact lens wearers surveyed
reported suffering from the symptoms of halos (52% and 56%,
respectively) and glare (47% and 50%, respectively) more than three
times a week.
- More than four of five patients who experienced these symptoms
found each symptom bothersome (84% and 89% for halo and glare,
- Spherical aberration, which can contribute to irregularities in
the visual system, can create halos and glare. Spherical aberration is a
type of image blur caused by light rays striking the lens periphery
where they are bent too much – over refracted – compared with rays
coming through the center of the lens.
“We know that during
low-light situations, our pupils become larger, and halos and glare are
more prevalent. This means everyday activities, such as driving at
night, can be impacted as our vision is affected by spherical
aberration,” said Nick Dash, BSc, MCOptom. “It is important for eye care
professionals to discuss vision in low-light situations with their
patients to ensure solutions are identified for patients experiencing
halos and glare.”
These study findings indicate
that the severity of symptoms associated with halos and glare is
sufficient enough to impact patient satisfaction with prescribed vision
correction methods. Coupled with how bothersome patients tended to find
halos and glare, about 90% of these patients (90% for halos, 91% for
glares) reported having either no solution or one that was
unsatisfactory. Moreover, the same rate of these patients (89% for
halos, 87% for glares) expressed an interest in an intervention that
more adequately addressed these symptoms.
“At Bausch + Lomb, we believe
there is an opportunity for eye care professionals to address these
common and bothersome symptoms with their patients,” said Carla Mack,
O.D., F.A.A.O., director, Global Medical Affairs for Bausch + Lomb.
"Some spectacle designs
as well as aspheric contact lenses may help patients achieve optimal visual correction with no halos or glare".
The study, commissioned by Bausch + Lomb, was conducted by an
independent market research firm, Market Probe: Europe. Additional
analyses and reports from the exhaustive data obtained in NSIGHT are
expected to appear in optometry journals and professional congresses
