Background
The eye lens is a biconvex transparent tissue, one of the important refractive interstitials in the eyeball, and is also an ionizing radiation sensitive tissue. When the eye lens is irradiated by a single large dose or multiple small doses of radiation, radiation damage can be caused to cause eye lens pathological changes, lens turbidity is formed, and cataract can be developed more seriously.
During the practical activities related to ionizing radiation, the head and the eye lens may be irradiated by higher dose of radiation due to the proximity of the head to the radiation source, the radiation field intensity or the lack of eye protection. For example, personnel involved in medical interventions, radiopharmaceutical preparation, etc., and personnel involved in nuclear fuel production, nuclear power plant maintenance, nuclear facility decommissioning, radioactive waste treatment, etc., in the nuclear industry, are high-risk groups.

Recently, according to epidemiological investigations, international authorities (such as international atomic energy organization IAEA and international radioprotection committee ICRP) have drastically reduced the annual dose limit of occupational exposure to ocular crystals, from the original 150mSv per year to an annual average dose of no more than 20mSv over 5 consecutive years, and the dose equivalent of no more than 50mSv in any single year. This important change makes dose monitoring and safety protection of the ophthalmic lens particularly urgent and essential.
