Your eye lens is crucial for performing all your vision-related activities, from reading, driving, to television watching. Any disturbance to these lenses may lead to unclear vision and other complications. Worldwide, cataracts affect numerous population, especially those over the age of 40. As a matter of fact, cataracts have become a very common eye disorder. Since early symptoms of cataracts are quite noticeable, it is important to get the affected eye checked thoroughly in order to prevent some more severe symptoms and signs of this eye vision problem.
Early symptoms and signs of cataracts
Cataracts, most of the time, do not trigger emergencies. This vision problem usually occurs as a minor disturbance to one’s eye lens that leads to blurry, cloudy visions. Early signs of cataracts are often noticeable and in some cases, proper eye glasses or contact lenses can be helpful to improve these symptoms, so that more severe cataract progression can be inhibited. In its initial formation, cataracts often trigger some symptoms, such as:
- Cloudy, blurry, or dimmed visions.
- Difficulty seeing to more specifically, driving at night or in the dark.
- Seeing halos around bright lights.
- Over-sensitivity to glares.
Cataracts, in addition to senior citizens, may also occur in children and even infants. There are some early signs that the children may develop cataracts, which include:
- Poor vision, which is commonly signed by children’s difficulty in recognizing and following objects or people with their eyes.
- The children’s eyes are pointing in different directions. This condition is known as squint, wherein one eye looks forward to focus on an object, another one turns either inwards, outwards, downwards, or upwards. Squint may not be constant and thus, in children with cataracts this condition may be noticeable when the children try to see certain objects more clearly. Squints can lead to blurred or double vision, although children often do not realize this.
- Nystagmus, or rapid uncontrolled eye movements known also as wobbling eyes. In children with nystagmus, swinging motion of the eyes makes it difficult to stay fixed and focus on a certain object.
- A white or greenish pupil, which may also sign a retinoblastoma.
More severe symptoms of cataracts
Cataracts commonly keeps progressing, although in most cases, very slowly. If glasses and contact lenses can help you see things clearly despite the cataracts, surgeries may not be required. However, any severe symptoms of cataracts should be put into account, as untreated progressing cataracts may cause more damage to the eye lens, leading to the risk of vision loss. This becomes more crucial if you have got some other health complications, such as diabetes and other eye problems, such as glaucoma.
Some of severe symptoms and signs of cataracts which may need professional attention include:
- Loss of contrast sensitivity, which makes it difficult for the patient to differentiate shadows and visions, as they become much less vivid. Therefore, it can be difficult for people with severe cataracts to differentiate between the color of black and dark purple.
- Disturbing glare may be noticed, as light going into the eye lens is scattered by the cataracts. In addition to these glares, haloes may also be observed around lights. Hence, it is very difficult for people with severe cataracts to see objects with very bright lights.
- Double visions may occur and night vision will be diminished.
- Sudden changes in glasses prescription, so that your previous glasses or contacts cannot promote proper eye vision anymore.
Signs of cataracts in adults
- Cataracts do not appear as whitish spots or region of the eyes directly. However, if you are suffering from eye problem that triggers difficulty seeing, it is important to have your eyes checked for cataracts, especially if you have a family history of cataracts. This history can be one of those signs that you might be suffering from this eye disorder.
- Cataracts that have developed severely may turn the color of your eye lens. This lens discoloration in fact, is a sign that cataracts may have infested your eye lens, causing discoloration.
- Cataracts on eye can also be detected using a device called a slit lamp. This device will help determining the status of the eye lens. An eye lens that has been affected severely by cataracts will resemble a reflective lens layer and thus, may have glaring effects when there is sufficient light level. This eye lens may seem greyish or greenish and may also seem translucent.
