What is Astigmatism?
Astigmatism is a refractive error that implies that there is an irregular curve in the cornea
(corneal astigmatism) or in the lens (lenticular astigmatism). They typically have a smooth
surface that curves evenly in all directions. Your vision, both near and far, is blurry and objects
will be seen distorted.
Who suffers from Astigmatism?
Astigmatism affects adults and children and is often accompanied by myopia (nearsightedness)
or hyperopia (farsightedness). Adults with high astigmatism may notice distorted vision,
especially at night. Children with symptoms of astigmatism often complain of headaches.
How is astigmatism corrected?
Astigmatism is corrected by glasses, contact lenses, and refractive surgery.
What is presbyopia?
Presbyopia is the age-related eye condition that makes it difficult to see things up close. Over
the years, our eyes age, and the crystalline lens (natural lens of the eye), previously
transparent and flexible, becomes rigid and opacities may appear. This makes us unable to focus on nearby objects.
Who suffers from presbyopia?
Presbyopia affects people over 40 years of age.
How is presbyopia corrected?
Presbyopia is corrected with glasses, contact lenses, and refractive surgery.
