A Spanish doctor has created a filter for contact lenses that screens out dangerous rays of light.
The yellow filter, which works for both natural and artificial light, is the brainchild of Dr Celia Sanchez Ramos, reports thinkspain.com.
She hopes that it will be produced commercially in the near future and has already received awards for the creation, including the Intellectual Property Organisation"s best inventor title for 2009.
In addition, the filter is said not to affect the wearer"s view of colours or to be visible once worn.
Older people whose natural filter is weakened may benefit from the invention, as may people who work in professions in which they are exposed to a lot of light.
Last week, littleabout.com reported how a woman who suffered disfigurement of her eyes has regained her confidence with contact lenses hand-painted by an opthalmologist.
Dr Jontahn Gording provided the lenses to Debbie Hershinger, who has a permanently enlarged pupil after a car accident.
