Cataracts are a clouding of the natural lens of the eye. The lens sits behind your pupil, that’s the black ‘dot’ at the middle of our eye.

As there spreads a cataract, the lens will become more and more opaque. This means that light may be prevented from reaching the retina at the back of the eye. Additionally, it can distort the light. This could result in even a total loss in vision.

Approximately 50% of people over 75 year age have cataracts. Moreover, 24.4 million Americans over the age of 40 are affected by different types of cataracts. Here is a brief description about 7 types of catarcts:

Nuclear Cataracts

Nuclear cataracts are probably the most frequent out of most types of cataracts. It’s a standard consequence of aging. Gradually, the region of the eye — that the ‘nucleus’ — starts to harden and turn yellowish.

As the cataract develops, it is going to disperse to other areas of the lens from the center. This decreases the total amount of light.

Cortical Cataracts

These simply take shape on the edge of one’s lens. They start like triangles that point towards the middle of one’s eye, as wedges. They scatter light Because they grow.

The principal symptom is glare when you’ve got cortical cataracts. You may discover that it’s hard to drive through the nighttime. They can make your vision blurry as if you are looking through a fog. You might find it really tough to tell colors that are similar apart or to estimate just how far away an object is.

Posterior Subcapsular Cataracts

Posterior capsular cataracts form on the back side of the lens, rather than on front like in a cortical or nuclear cataract.

These sorts of cataracts are more prevalent in people who are diabetic. It more commonly occur in people who have been taking oral drugs, which can be occasionally prescribed to treat arthritis.

Congenital Cataracts

These are cataracts you’re born with or form whenever you are a kid. Some are associated with your own genes, and others are the result of a sickness, such as rubella, your mother had during pregnancy.

Radiation Cataracts

You must know that it’s vital to protect your skin from sunlight’s ultraviolet (UV) radiation, however it may have a toll on your own eyes, too. If you spend time in the sun without eye protection, you can at times get cataracts.

Individuals working outdoors, like fishermen and farmers, are more likely to get this kind of cataract. To stop, wear sunglasses with 100% UVA and UVB protection.

Traumatic Cataracts

Some kinds of cataracts could be caused by injuries.

Eye injuries, or attention traumas’, are quite typical, one-fifth of adults may suffer from this type of injury at any time of their lives.

A person could be affected during an accident in the eye and this disrupts the fibers that form the lens — resulting in a cataract.

Secondary Cataracts

When any other condition or treatment leads to cataracts, health practitioners call it secondary. Diabetes, taking steroids like prednisone, and sometimes even cataract surgery are possible causes.

Conclusion

Generally speaking, if you’re finding it tougher to see clearly and if you are of the age 45 or above, you ought to speak with an ophthalmologist to lookup for early signs of cataract development.
