An eye-care plan to tackle concerns people are going blind because they are not being diagnosed and treated quickly enough has been launched by the Welsh government.
Nearly 100,000 in Wales have sight loss problems and that number could double by 2050 as the population ages.
Regular eye tests and better use of opticians are among the new proposals.
The health minister said it was believed half the cases of blindness could have been prevented.
The Royal National Institute of Blind People (RNIB) said it hoped fewer preventable problems would arise.
Figures show around 75% of sight loss occurs in people over 65 and there are worries sight problems will only get worse as the population gets older.
The plan sets out a range of commitments:
- Annual eye tests for children in special schools and giving regular tests to elderly people in care homes
- More people should be treated closer to home
- Better use should be made of the skills of opticians to reduce the number unnecessary referrals to hospital
- It also aims to improve the range of services among optometry practices and will be monitored by a task group to ensure targets are met.
RNIB Cymru director Ceri Jackson said the problem was compounded because when people were diagnosed they did not always receive treatment fast enough.
"Sadly, we do hear of people who do lose their sight who are registered blind or partially sighted because they have not been seen in the time they when should be seen," she said.
"What I hope this plan will do is place more emphasis and priority around joining up those services across primary and secondary care so we do make sure people don't lose their sight unnecessarily."
The Welsh government launched its Welsh Eye Care Service in 2002 to improve early detection rates with optometrists dealing with two-thirds of eye problems in the community rather than referring patients to hospital.
Launching the new plan, Health Minister Mark Drakeford said estimates suggested that in half the cases reported complete sight loss could have been prevented.
Mr Drakeford said: "With cases of sight lost set to increase by 22% by 2020 and double by 2050 due to the ageing population, we have to act now.
"We need to ensure more people have regular sight tests and that eye health problems are detected early.
"People need to know where they can access services, care and support in their local area and also be assured they will have rapid access to services and support when they need it."
He said the plan would ensure services were in place to prevent and treat eye sight problems.
