What are eye cataracts?
Eye cataracts, an eye condition that affects about one in six past the age of 40, is one of the most common eye disorders in the world. Cataracts are a cloudy or opaque area on the crystalline lens of the eye that develops over time. Despite being so common, most cataract cases aren’t caught until they’ve progressed because they’re painless and the loss of sight is subtle. Either both or one eyes can suffer: To diagnose the condition, optometrists look for a yellowing in the lens of the eye and an opacity in the back capsule.
Cloudy or blurry vision
First, always take steps to take care of your eyes – like employing these 13 vision boosting tricks. With cataracts, you might have a localised blurred spot or a generalised decrease in vision; either way, impaired eyesight will likely be the first thing you notice. A cataract will start out small and initially have very little effect on your vision, though you may notice the world beginning to resemble an impressionist painting or a cloudy piece of glass. “Blurry vision is the number one symptom of cataracts,” says Joseph Fishkin, MD, comprehensive ophthalmologist and cataract surgeon. “Blurred vision can be caused by many different problems but, as cataracts develop, vision gets more blurry over time. The natural lens in our eye helps light focus properly, and this normally clear lens slowly becomes more cloudy.” Because this is difficult to differentiate from other diseases such as glaucoma, it’s important to consult your optometrist as often as possible if you notice these changes.
Decreased colour perception
Due to the clouding of the eye, colours can become less vibrant and increasingly muddy over time. “Real” whites will appear much more yellow in comparison. Because this occurs at such a slow and gradual pace, most patients won’t notice colour changes until after surgery is done to remove one or both cataracts. “When people develop cataracts, there is a marked fading or yellowing of colours, which is sometimes noticed,” says Michael Nordlund, MD. “One of the most prominent improvements in vision after cataract surgery is a marked improvement in colour vision. Patients often comment following surgery that they don’t ever remember seeing such vibrant colours. In fact, we are just restoring the colour vision of their youth.”
