Light-induced ocular damage has been investigated for decades in laboratory extensive work and several epidemiological studies. More recently, harmful effects of blue-violet light have been spotlighted by growing body of scientific research. Despite the eye’s natural defense mechanisms, it has been evidenced that cumulative exposure to blue-violet light can contribute to long-term irreversible changes in the retina. When the most critical exposure occurs in outdoor conditions, Transitions® lenses can effectively filter harmful blue-violet light and consequently provide optimal photo-protection for the patient eyes.

Symptoms of discomfort are common among patients who spend considerable time performing tasks at near viewing distances – such as is common among computer users.
Although the symptoms can be vague and seem elusive, they can usually be eliminated or reduced by diagnosis and treatment of the work arrangement and the visual system – including proper spectacle correction of presbyopia.
This article summarizes clinical management of vision-related discomfort.

Annual exposure to solar radiation is three times higher in children than adults. Moreover, because of their physiology, children’s eyes are more vulnerable and require special protection against UV rays and blue-violet light. Designed for children as well as adults, the new Crizal® Prevencia® lenses are completely transparent, providing optimal photo-protection from day to day. The use of sunglasses will ensure additional protection in direct sunlight.
