What is an isometropia?


Understanding vision problems can be hard enough with the mechanics of the issue, let alone deciphering the jargon that comes with it. Most of the time, however, these issues can be easily explained.

Anisometropia is a condition in which there is a significant difference between an individual's eyes. To break this down further, for example, one eye could be myopic (short sighted), while the other hyperopic (long sighted). This sort of variation makes it difficult for the brain to interpret the images coming in, because they appear to be different sizes. Most people do not suffer from this sort of variation. Rather just one of these conditions, which means their glasses or contact lenses can have a similar prescription to correct the vision in both eyes. For example short sighted in both eyes, or longsighted in both eyes. Anisometropia, on the other hand, can cause one eye to lose focus and wander, depending on whether the object focused on is near or far. People who deal with this issue will often find ways to deal with eye wandering by refocusing - however, this will likely cause eye strain very quickly and result in soreness and headaches.

In the case of anisometropia, a vision solution must be reached that caters to each difficulty.The first step is to take a test to determine the extent of the issue in each eye. From there, a qualified optometrist will be able to talk you through the best solution for your situation. Contact lenses are commonly prescribed to improve eyesight, as they can help balance out the differences in vision, although spectacles can be used in a similar way. Another way to deal with the issue is to wear a soft contact lens in one eye and adjust the prescription for glasses accordingly. Often, dealing with anisometropia will take a fitting and a trial, as each solution must fit the issue itself.

Another possibility is laser refractive surgery, although there are restrictions on who can use this option to fix anisometropia, as it depends on the prescriptions.In some cases, anisometropia can lead to amblyopia. This condition is otherwise known as 'lazy eye' and is characterised by eyes that turn in or out, eyes that don't move together to look at the same object, the inability to correctly judge depth or poor vision in one eye.Anisometropia is not uncommon and can cause discomfort. The best way to deal with this ailment, and any other eye issues, is to speak to an optometrist about booking a test to determine the extent of the issue and the best ways to improve the situation through top quality technology and care.
