Long-sightedness (Hyperopia)
  • You are long-sighted if nearby objects appear out of focus and distant objects appear clearer.
  • Long-sightedness or Hyperopia causes people to squint in order to see clearly.
  • Close work, especially for long concentrated periods will make the eyes feel tired (such as reading, computer work or writing).
  • Children with mild hyperopia (as the eyes are still developing) usually have the flexibility to focus on close objects.

Causes of long-sightedness or hyperopia

Hyperopia occurs when light entering the eye from close objects is focused behind the retina. The lens inside the eye is unable to 'accommodate' the refractive error sufficiently by becoming 'fatter' to establish clear vision.
Long-sightedness can have a number of causes:

  • The eyeball being too short.
  • The cornea is too flat ( not enough curvature to refract the light onto the retina.
  • The lens inside the eye not becoming 'round enough' to accommodate.
  • Inheritance of long-sightedness from parents is possible.
  • Diabetes.

Long-sight, clinically referred to as Hyperopia, occurs when objects close up appear blurred or when 'close work' is possible but becomes uncomfortable due to eyestrain and fatigue after a period of time.

From time to time headaches may also occur. However, distant objects such as road signs are perfectly clear. Often, people can overcome this blurred effect when looking at near objects by over exerting the muscles within the eye to achieve a clearer focus. Of course with time, this tires the visual system and the eyestrain and headaches will arise.


Hyperopia is caused by a variation in the shape of the eyes - namely the eye being too short from front to back, or the power of either the cornea or lens being slightly weak. The result is a mismatch between the length of the eye and its focusing power. Therefore the light rays do not meet at the retina and images are not seen clearly.

The cornea, the clear window at the front of the eye, accounts for up to 80% of the focusing power of the eye. It is this part of the eye that can be altered through laser eye surgery to alter its refractive properties and thereby reduce the hyperopia in the eyes.

Is Laser Eye Corrective Surgery Right for You?

At AccuVision your safety and total satisfaction are paramount. Laser eye corrective surgery may not be suitable for everyone and a successful outcome is dependent on many factors which must be carefully considered.

Laser Eye Treatment and Eligibility

Whether or not laser treatment can be performed on your eyes depends on a number of factors that needs to be assessed by our eyecare specialists at your initial consultation.

Although the majority of people who come to us are eligible for treatment, due to the high prescription levels we are able to treat, we may decline to treat you if the outcome cannot be accurately predicted or if laser eye surgery treatment is likely to cause complications to your sight. Your lifestyle and occupation may also be an important consideration.

In general, the suitability of our laser eye corrective surgery procedures for you depends on factors such as:

  • The degree of optical error
  • The thickness of your cornea
  • The existence of any eye disease
  • The size of your pupil
  • Corneal mapping data
  • Wavefront analysis results

You should ideally be able to answer YES to the following:

  • Do you suffer from short-sightedness, long-sightedness or astigmatism?
  • Are you over 18 years old?
  • Is your prescription stable?
  • Are your eyes healthy and free from any eye disease?
  • Would you rather not wear glasses or contacts on a permanent basis?

Please note that this is only intended as a general guide and there are always exceptions. Detailed analysis of your eligibility for treatment using laser eye corrective surgery can only be achieved at your consultation, but please call us if you wish to discuss the current condition of your eyes and their suitability for treatment on 0330 123 2020
