Farsightedness

Farsightedness or hyperopia is a vision condition where distance vision is blurred and close vision clear. Farsightedness usually occurs in young people, when they cannot see clearly, things at a distance. This condition if not corrected can lead to blurred vision, headaches and eyestrains.

Farsightedness occurs when the cornea or lens of the eye is not able to curve enough to bring light to a focus on the eyeball. While in some cases the lens curvature poses the problem, in others, the eyeball is smaller, therefore not providing the right distance to match that of the lens and the cornea. Many people compensate this condition by squinting or focusing too hard on the distant object. This is called accommodation and can result in headaches and eyestrains.

The extent of farsightedness can be detected by an eye exam performed by an optometrist or a professional eye care practitioner. To correct farsightedness, a convex or plus lens is prescribed. It is usually thicker at the centre and thinner on the edges. Farsightedness can also be corrected with spectacles and refractive surgery.

Farsightedness is one of the most common vision problems that afflicts nearly 30% of the population and genetics can also be an added risk factor. Read more on contact lenses and children, where many young people can also be successfully fitted with contact lenses.
