Life insurance was the most popular voluntary insurance product in 2005, but sales of vision coverage and several other health-related products grew quickly.

Researchers at Eastbridge Consulting Inc., Avon, Conn., have published data supporting that assessment in a summary of a survey of 60 worksite marketing carriers.

Voluntary life insurance accounted for 24% of 2005 worksite sales and disability insurance came in second, according to Eastbridge researchers.

The researchers note that sales of voluntary long-term disability insurance fell 29%.

Sales of vision coverage, which has only a small percentage of the market, increased 46%, while sales of hospital indemnity plans and limited-benefit medical plans grew about 15%.

Sales of critical illness insurance were up about 13%, Eastbridge researchers report.
