Multifocal contacts lenses, often prescribed to people with presbyopia (an age related eye condition that makes reading and other near work difficult), have been linked to problems with driving at night.
An article published in Investigative Ophthalmology & Visual Science describes how people wearing the lenses have a harder time recognizing road hazards. Though the subjects could read the road signs, they had to be closer to see them clearly than when they were wearing glasses.
Researchers hope that their findings will help move manufacturers to improve the optical quality of their multifocal lenses.

An increase in the use of contact lenses may be making ulcers of the cornea twice as common. A study of over a million Californians showed that people who wore contact lenses were 9 times more likely to suffer from corneal ulcers.
Researcher Dr. David Gritz of Montefiore Medical Center in New York told Reuters Health: “As new contact lens innovations become available, and people hear that they can wear these contact lenses for weeks or a month without taking them off, they do just that. They don’t realize the dramatic increase in risk it causes them. Our eyes do need breaks from contact lens wear.” He went on to say, “Contact lenses can even act as a bandage over eye irritation, covering up symptoms.”
People infected with HIV were also nine times more likely to develop the condition than those who were HIV negative.

Astigmatism is caused by irregularities in the shape of the cornea or lens. It can be treated through the use of corrective lenses, including contacts.
Symptoms include:
- Blurred or distorted vision at all distances
- Photophobia – sensitivity to light
- Headaches
- Excessive squinting.
- Constantly closing of the eyes
- Eye strain – occurs more often when the eye has to focus for long periods, as in reading from paper or a computer monitor
Computer eye strain is associated with this condition: computer eye strain can cause or exacerbate astigmatism or astigmatism may worsen the symptoms of computer eye strain. For more on computer eye strain and how to prevent it, click here.
