Amblyopia is not a type of eye disorders that produces various symptoms. Quite the contrary, this problem is often unnoticed due to its limited symptoms and signs. This is possible as amblyopia often affects children more than adults. Children in very young age are even more susceptible, as amblyopia is one of eye disorder from birth, so that parents often fail to observe the symptoms that may not visible physically. When this problem is unnoticed and thereby, left untreated, visual imparity caused by amblyopic eye may persist to adulthood. In many cases, the symptoms and signs of amblyopic eye are in fact more visible during adulthood.
Noticing amblyopia symptoms
Amblyopia symptoms generally begins in childhood, as this is an eye disorder commonly brought with birth. Unfortunately, it is not easy for young children to make their parents know there are something wrong with their visual ability, especially if the symptoms are not physically visible. In some cases, parents do notice something is not right with their children’s vision through their body language, such as frequent squinting and head tilting. Strabismus is another noticeable symptom of potential amblyopic eye development, especially the one caused by misaligned eyes.
Amblyopia symptoms in adults
Most common symptoms of amblyopia that can be observed more during adulthood than childhood include:
Blurry vision in the affected eye
Blurry vision is the most frequently-occur symptom of an amblyopic eye. This symptom almost always occurs as an amblyopic eye does receive limited optic signals from the brain that it has difficulty in synchronizing the focus with another eye. As a result, blurry visions are produced.
Reduced visual ability in the affected eye
Amblyopia that has not been treated during childhood increases the risk of reduced visual ability later in the adulthood. Vision of the weaker or lazy eye is most affected, that it is difficult for the patients to perceive things using this affected eye. This visual ability may also affect the stronger eye if the amblyopia is not fixed immediately. Many people suffering from residual childhood amblyopia also experience total loss of visual ability of the amblyopic eye eventually.
Amblyopia is often triggered by misaligned eyes that may lead to the symptom of double visions. In misaligned eyes, light rays from outside may fall either behind or in front of the retina, instead on the retina, so that two different visions are produced. This refractive problem is quite common in adult amblyopia.
Another visible symptom of amblyopia in adults is squinting. Although this is also a common symptom of childhood amblyopia. In order to gain a better focus, people with amblyopic eye commonly squint a lot. This is a symptom you should notice better during adulthood, as you might do it more frequently to seek for adequate focus of the eyes.
Lack of team work between both eyes
This is also a symptom of prolonged amblyopia. As without adequate treatments the weaker eye does not receive sufficient optic signals from the brain, it is hard for this eye to work in a good coordination with the unaffected eye. As a result, the stronger eye, which receives better optic signals from the brain may be able to focus to the perceived objects, while the weaker one may move inward, upward, outward, or downward, without being able to perceive the objects properly.
Poor depth perception
This symptom occurs along with prolonged amblyopia that is not treated properly. As the visual acuity of one or both eyes gets worse and thus, those seem to not cooperate quite well, poor depth perception cannot be acquired by the patient. In children with initially treated amblyopia, this symptom might not occur, although this depends on various risk factors other than the age itself.
Can glasses help correcting these symptoms?
In fact, amblyopia treatment is quite complicated, as it is advised to be performed during the critical period—before the patient reaches the age of 10. Moreover, amblyopia is not a type of eye disorder that can be corrected with eye glasses or contact lenses. If the problem was not corrected during childhood, consistent vision therapy can be helpful to minimize the effects of amblyopia in adulthood.
