Refractive errors in incidence / prevalence
A refractive error is a problem with the eye’s ability to focus light accurately on the retina due to the shape of the eye.
Rates vary between regions of the world with about 25% of Europeans and 80% of Asians affected.
Refractive error types
The most common types of refractive error are:
- near-sightedness (myopia)
- far-sightedness (hypermetropia)
- Presbyopia (affects most people over the age of 45)
Refractive errors diagnosis and examination process
The diagnosis of a refractive error is usually confirmed by your optometrist during an eye examination using a number of lenses of different optical powers.
Refractive errors treatments
It’s possible to treat refractive errors with glasses and contact lenses; however, the inconveniences that come with these visual aids make vision correction surgery an attractive alternative.
Laser eye surgery or lens replacement can correct your refractive error and remove your dependency on glasses and contact lenses altogether.
