If you have hyperopia, it means that distant objects – movie screens, road signs, classroom boards, etc. – can be seen normally, but nearby objects – such as a book or computer monitor – may be blurry and harder to see.
Hyperopia is a refractive error – a vision impairment caused by the shape of the eye – as opposed to an illness or disease. There are four refractive errors, the other three being myopia, astigmatism, and presbyopia.
Hyperopia is more commonly referred to as farsightedness.
There are many causes of refractive errors, including the size and shape of your eye (as well as the curvature of the cornea/lens).
To understand what a refractive error is and how it influences sight, we have to first understand how our eye sees:
There are three main causes of farsightedness:
Modern vision correction is more effective at treating farsightedness than ever. There are two main ways to correct hyperopia: corrective lenses and laser refractive eye surgery.
Worn in the form of spectacles (eyeglasses) or contact lenses, corrective lenses have been the staple in the eye care world for over 100 years (for eyeglasses, contact lenses first came to market in the mid-1960s).
Nearly 70% of Canadian adults wear eyeglasses or contact lenses to provide clear vision.
A long-term and often permanent solution, this minimally invasive surgical procedure is performed tens of thousands of times per year across Canada. Compared to corrective lenses this surgery is a more involved and long-lasting process.
While refractive surgery is quite safe, there are risks of side effects and complications. Read more about laser eye surgery.
