Solar Eclipse

How to see the solar eclipse of next July 2 without damaging the eyes? Recommendations of Dr. Luciana Ballesté, eye professional of Río Cuarto city, next to the School Health Sciences - Universidad de Mendoza Headquarters Río Cuarto.

The province of Córdoba will be one of the "ideal places" to observe total solar eclipse that will take place next July 2. Phenomenon that will not be repeated itself in this region of the planet for 375 years.

It is usual that, during this type of phenomena, we look directly at the sun, which emits radiation that damages the retina.
Through this note, we tell you what are the recommendations to take into account to prevent eye damage; thanks to the collaboration of Dr. Luciana Ballesté of the professional team of Oftalmos Río Cuarto.

The harmful effects that the Solar Eclipse could generate on the eye are due to the ultraviolet and infrared radiation that the light emanating from the sun possesses. They could produce a lesion called "radiation retinopathy," where photoreceptors in the macular area of the retina are damaged.

These radiations can also cause lesions on the surface of the eye and cataracts. Eye manifestations are not immediate onset, usually appear 6 to 12 hours after exposure.

The symptoms that appear are irritation, swelling, burning, tearing, progressive reddening of the conjunctiva, followed by pain that does not allow to open the eyes, and cloudy vision.


• Do not look at the eclipse directly without adequate protection. There is an indirect method for its observation.
• For direct observation, use SPECIAL LENSES created for this purpose, with ISO 12312-2 label, which must not present scratches or perforations. Another option is to use a soldering mask, grade 14 or higher.
• Despite the protection, it is not recommended that the observation time exceed 30 seconds.
• DO NOT USE radiographic plates, polarized lenses, or common sunglasses. They do not have the ability to stop the totality of radiation.
• We recommend the use of protective lenses 5 or 800 UV protection index. They should bear in mind that seeing a solar eclipse carries a risk of 80% chance of damaging the retina. Therefore, we recommend watching it on television or online, if you do not have adequate means of protection.
