Refractive errors
Refractive errors include
Farsightedness
With farsightedness, we see well-distant objects. The problem is reading or watching TV. Children refuse to draw, paint, sit closer to television, and fail at school.
Myopia
Myopia is a visual error, also referred to as a refractive error. The rays of light are directed in the lens of the eye to create a sharp image on the retina. In myopia, the rays converge in front of the retina. The result is a blurred image and poor visibility of distant objects.
Amblyopia
Amblyopia affects approximately 4% of children. Early detection and early treatment are important. Otherwise, permanent complications are a threat.
Astigmatism
Astigmatism is a common visual acuity disorder. Do you see out of focus, blurry, have headache or have night vision issues?
Presbyopia
Presbyopia occurs mostly after the age of 40. It affects everyone as a result of the natural aging process. The first symptom is the inability to focus on near objects. The impairment is also known as "short arm syndrome", since reading material must be held further and further away in order to be sharp.
