Eye Damage From the Eclipse: "You Don't Notice that It Happens"
Experts say certified solar viewing glasses that block 99% of light are needed, as eclipse viewing can cause painless, permanent central vision loss.
A partial solar eclipse will darken skies across Ireland and Europe today, prompting health officials to warn that staring directly at the sun can cause permanent, irreversible eye damage.
Consultant Ophthalmologist Mark Cahill warned that solar retinopathy is painless yet irreversible, with damage building over days as heat harms the retinal pigment beneath the macula.
The HSE advises using certified solar glasses marked with ISO number 12312-2, which block 99% of light and filter UV and infrared rays; experts cautioned against telescopes, binoculars, and X-ray film.
Gerry Fahy, president of the Irish College, emphasized that children are particularly vulnerable because their clear natural lenses allow more ultraviolet rays to reach the retina, requiring strict parental supervision.
Beyond eclipse safety, the College recommends full eye checks every couple of years for those over 50, while maintaining a healthy diet and managing screen time remain vital for long-term vision health.
"The sun damages the retina without warning, but the lesions are irreversible," explains Dr. Florence Ribeaudeau on LCI. "It also confirms the idea that, without adequate protection, it is possible to lose sight. (Sciences).
There will be a solar eclipse in Hungary on August 12. A man who suffered permanent retinal damage 27 years ago is now warning about proper eye protection.
