Solar Eclipses Eye Safety: Protect Your Eyes from the Sun!

SHARE NOW

The Ohio Department of Health is concerned with your vision during the upcoming solar eclipse.

They recommend that you never look directly at the sun during a solar eclipse (except during the very brief time the sun is in total eclipse; and even then, with caution).

Looking directly at the sun can cause permanent damage to your eyes.  After viewing a solar eclipse, seek treatment from an eye care professional if you or your child have any changes in vision that continue to get worse.

How can your eyes be affected by a solar eclipse?

Exposing your eyes to the sun without proper eye protection during a solar eclipse can cause “eclipse blindness” or retinal burns, also known as solar retinopathy. This exposure to the light can cause damage or even destroy cells in the retina (the back of the eye) that transmit what you see to the brain. This damage can be temporary or permanent and occurs with no pain. It can take a few hours to a few days after viewing the solar eclipse to realize the damage that has occurred.

Consider your eye health when watching a solar eclipse. The only time that you can safely view a solar eclipse without special equipment is during the part of a solar eclipse when the moon completely covers the sun.

It is never safe to look at a partial solar eclipse without proper safety equipment or techniques. During the very brief time the sun is in total solar eclipse it is safe to look at it, but do so with caution. Even during a total solar eclipse, the eclipse may last only a short period, and if you are looking towards the sun as the moon moves away from blocking the sun, you might get a solar burn on your retina which can cause permanent damage to your eyes. Talk with your eye care professional to determine the best viewing option for you. Here are a few common ways to safely watch a solar eclipse:

Solar Eclipse Glasses

  • Use expert-approved solar eclipse glasses to view a solar eclipse safely and without damaging your eyes.
  • Make sure they meet safety requirements and are manufactured with the ISO 12312-2 standard. Look for ISO standard labeling when looking for solar eclipse glasses and purchase them from a trusted source.
  • Wear your solar eclipse glasses at all times when watching an annular or partial solar eclipse.
  • Wear your solar eclipse glasses at all times during a total solar eclipse, except during the very brief time the sun is in total eclipse; and even then, with caution.

Note, that solar eclipse glasses can be damaged. If the lenses of your solar eclipse glasses appear torn or scratched, they are not safe to use.

Other Options

Welder’s glass: Number 14 welder’s glass provides effective protection and can be found at a local welder’s supply store. This glass will reduce the harmful rays that are emitted during the eclipse. Do not use it if there are any scratches or damage to the glass.

Mylar filters: Aluminized mylar plastic sheets are available as eclipse vision glasses or can be cut and made into a viewing box. Do not use it if there are any scratches or damage to the sheet.
