Cloudy or blurred vision can be caused by presbyopia and refractive errors (myopia, hyperopia and astigmatism), it can also be due to more serious problems such as eye diseases or neurological disorders, as explained by specialists.
Sometimes, Blurred vision may be accompanied by symptoms such as nausea, headaches, and tiredness.
According to the portal specialized in ophthalmology Martinez de Carnerosmyopia is one of the refractive errors that produces vision problems in one or both eyes, in addition to conditions such as strabismus, eye fatigue and headache. “Myopia is the most common refractive error and causes objects located at distant distances to be blurred,” the specialists indicate.
According to the portal Mayo Clinica nonprofit organization dedicated to clinical practice, education and research, myopia occurs when “the shape of the eye causes light rays to bend (refract) incorrectly, which focuses images in front of the retina instead of on the retina”.
Astigmatism can also be another cause of blurred vision. Experts comment that one of the most common solutions is usually glasses or contact lenses to correct these pathologies.
“The abuse of screens, stress or lack of sleep can cause, usually temporarily, that we see blurry”, warns Dr. Carlos Lisa Fernández, ophthalmologist at the Cornea and Lens Unit of the Fernández-Vega Ophthalmological Institute (IOFV) , in words collected by the portal Know how to live.
Blurred vision occurs because dryness or lack of lubrication causes difficulty focusing on objects.
To treat dryness, experts advise giving your eyes a rest, especially when you spend many hours in front of the computer or looking at your cell phone, either for work reasons or for entertainment. Using artificial tears to moisturize helps reduce the risk of blurred vision.
When blurred vision is in both eyes it can be caused by:
Experts indicate that in some cases it is necessary to carry out medical tests to discover the cause of blurred vision, in addition, this helps to have a diagnosis to take timely measures.
- Optical coherence tomography (which is used to explore the retina).
- Corneal topography (which, like the previous one, is non-invasive and is used to find out how the cornea is).
- Optic nerve fiber analysis
- The taking of the ocular tension by means of a tonometry.
Medline Plus, The US National Library of Medicine website notes that You should go to an emergency medical center if the following symptoms occur:
- Partial or total blindness in one or both eyes, even if it is only temporary.
- When you have double vision, even if it is temporary.
