A refractive error is a very common eye disorder. It occurs when the eye cannot clearly focus the images from the outside world. The result of refractive errors is blurred vision, which is sometimes so severe that it causes visual impairment.

- Myopia (nearsightedness): distance objects appear blurry, while near objects appear clear
- Hyperopia (farsightedness):distance objects appear clear, while near objects appear blurry
- Astigmatism: distorted vision
- Presbyopia: means aging eye – is an age related eye problemin which patients start developing this problem around the age of 40 years.
The main cause of refractive errors if Blurred Vision, in some cases even double vision, glare, etc, etc.
Glasses or contact lenses can usually correct refractive errors. Laser eye surgery can also be done if required.
