According to the recent report published by the World Health Organization, about 2.2 billion people globally have vision impairment. To prevent blindness, many of these individuals seek vision correction. What type of vision impairments do they need vision correction to resolve? Let’s find out!
Four Refractive Errors Requiring Vision Corrections
- Myopia - Myopia, also known as nearsightedness, is an abnormal eye shape causing light to come to focus before hitting the retina behind the eye.
- Hyperopia - Hyperopia, also known as farsightedness, is an abnormal eye shape causing light to come to focus at the back of the retina.
- Presbyopia - This is also farsightedness that comes with age. At this stage, the eyes lose their ability to shift focus forth and back between closer and distant objects.
- Astigmatism - This leads to distorted images. It often happens when the cornea is elongated instead of round.
People with these four conditions are often candidates for vision correction. Nevertheless, an eye doctor considers several factors before deciding whether contact lenses, glasses, or vision correction surgery is the best for a patient.
Factors To Consider Before Choosing The Right Type Of Vision Correction
- Day-to-day Activities - For reading or driving, glasses might be practical. For all activities, surgery or contact lenses will be a better option.
- Health Status - Vision correction surgery is not fitting for presbyopia.
- Personal Preferences - Personal preference plays a significant role in the type of vision correction that fits you.
- Overall Health - Chronic conditions might make you unfit for certain vision correction surgery.
- Lifestyle - Jobs, hobbies, and sports can influence vision correction choices.
