SNEC Explains: Presbyopia

Are you experiencing blurred near vision when reading or working on the computer? You could be suffering from Presbyopia ('Lao Hua').

What is presbyopia?

Presbyopia (Lao Hua) is an age-related condition in which a person is unable to focus on near objects. Presbyopia is an inevitable natural aging process of the eye and usually begins at around 40 years old.

What causes presbyopia?

Presbyopia (Lao Hua) occurs when the natural lens in the eye loses its elasticity and ability to change shape as a person gets older. The loss of elasticity in the lens makes it less able to focus light accurately when looking at near objects.

How do I correct my presbyopia?

Presbyopia (Lao Hua) can be corrected with special spectacle lenses called bifocals to help correct the condition and any other existing refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness) or astigmatism.
