Squints or Turns
Squints usually first appear in early childhood. They are caused by a slight imperfection of one or more of the 6 ocular muscles that control the movement of each eye. Even the slightest variation in the length of one of these muscles can cause one eye to fail to coordinate with the other, so that your eyes appear to be looking in different directions. Usually the “rogue” eye will be turned in or out, but sometimes it can be up or down.
Most squints can be treated by exercises (orthoptics) or by wearing suitable glasses or Contact Lenses. If you have a squint you may have been told that you are unsuitable for Contact Lenses. This is not always the case, but you do need to see a specialist Contact Lens Practitioner as most Opticians don’t have the skill to fit these lenses – in fact many Opticians refer these patients to The Contact Lens Practice as they know that Geoff and his team will be able to help. Even if your glasses incorporate special lenses (prisms) Contact Lenses can sometimes be made to have the same effect.
In a small number of cases exercises or corrective lenses may not be enough, necessitating a small operation to alter the muscle lengths.
Very occasionally, because of the presence of a squint, one eye may not learn to see to its full ability and has permanent poor vision which cannot be corrected with optically – this is often called a ‘lazy eye’.
