How to safely watch UK solar eclipse 2026 according to optometrist

Kyla Black, Boots Opticians Director of Optical Practice, is reminding the public about the risk of permanent eye damage ahead of the eclipse on Wednesday, August 12, which will be visible across the UK.

The event will see up to 90 per cent of the sun obscured by the moon in some areas.

Ms Black said: “Even when most of the sun is covered, it is never safe to look directly at it with the naked eye during a partial solar eclipse.

“Looking at the sun without the correct protection can damage the retina, which may lead to permanent vision loss.”

She explained that the reduced brightness during an eclipse can fool the eye’s natural defences, causing the pupil to dilate and allowing more harmful UV light to reach the retina.

This can result in serious and irreversible damage.

Ms Black recommended using only certified eclipse glasses that meet the ISO 12312-2 safety standard.

She said: “There are several safe ways to enjoy the eclipse, such as wearing certified eclipse glasses that meet the international ISO 12312-2 safety standard.

“Another option would be to watch the solar eclipse from the comfort of your own home on a livestream.”

For those hoping to capture the event, Ms Black advised caution with photography equipment.

She said: “Those that are looking to use a camera and take some photos can use specially designed solar filters.

“The same filters can also be used for the secret astronomers amongst us who own a telescope or simply a pair of binoculars.”

She warned that regular sunglasses, even very dark ones, do not offer adequate protection and that makeshift filters, such as smoked glass or X-ray film, are not safe alternatives.

Ms Black also advised parents to closely supervise children if they plan to view the eclipse.

She said: “Parents should be particularly careful if they are going to let their children view the eclipse and ensure they supervise them closely.”

The optometrist said the eclipse is a reminder of the value of good eyesight and the importance of regular eye care.

She said: “The solar eclipse is a wonderful opportunity to appreciate just how important our eyesight is.

“Taking a few simple precautions will help ensure you can enjoy the incredible event safely.”
