AmblyopiaAmblyopia or "lazy eye" is the decreased ability to see detail. During early childhood years the nerve pathway from the eye to the brain does not develop as it should which causes this condition. Amblyopia is by far the leading cause of decreased vision in children.
Amblyopia, or more commonly lazy eye, is poor vision in one or both eyes due to a lack of stimulation to the retina (the back inside surface of the eye that relays information to the brain) during the critical development period in childhood (from birth to around 7 - 8 years of age).
Common underlying causes of a lack of stimulation include squint (misalignment of the eye), uncorrected refractive error (e.g. long-sightedness or astigmatism), ptosis (droopy upper eyelid obscuring the pupil) and cataract.
It is very important that amblyopia is detected early (approximately before the age of 7 - 8years) in order to try to improve the weak vision. If amblyopia is not detected before this critical age, treatment is less likely to be effective.
We tend to be a bit laissez-faire when it comes to our children’s vision; the childcare nurse or the school will pick up any problem, we often assume. But unfortunately, many kids fall through the cracks.
Prism lenses may be prescribed by your optometrist for your eye glasses for double vision (or diplopia) depending on the eye condition you may have. Are you wondering how prism glasses work?
When it comes to myopia control, the good news is that there’s now a number of options to prevent or slow down shortsightedness. Clinical studies on both ortho-k and NaturalVue contact lenses are impressive – but which is best?
March 10th -16th is World Glaucoma Week. The problem with glaucoma is that you don’t feel anything. You don’t even notice anything wrong with your vision until 60% of it is permanently lost.
