Cataracts affect many people to varying degrees, particularly as they age.
People who wear prescription glasses may wonder about the effectiveness of their eyewear when faced with this condition.
Let's see whether prescription glasses can prevent or even treat cataracts.
Mainly affecting people over 65, cataracts are, in fact, an eye condition mainly due to the natural ageing of the eye.
When one or both eyes are suffering from cataracts, the crystalline lens becomes opaque.
By losing its transparency, this biconvex lens located behind the iris can no longer fulfil its function properly.
Consequently, the eye can no longer adapt properly to all the different distances.
As a result, vision is significantly reduced and cloudy, contrasts are less sharp and, in some cases, vision can be double or glare-sensitive.
Although cataracts are essentially linked to the ageing of the eye, in some cases they can appear more prematurely.
Diabetics, people overexposed to the sun and smokers in particular may be predisposed to this eye condition.
Cataracts can affect vision to varying degrees, even leading to blindness in some cases.
It is therefore essential to treat this eye condition quickly and effectively with surgery.
When cataracts appear naturally as a result of the ageing of the eye, nothing can prevent them, not even wearing prescription glasses.
However, glasses with polarised or photochromic lenses provide better protection against UV rays, which can also cause cataracts.
In this case, prescription glasses can help prevent cataracts or slow their progress.
Similarly, wearing sunglasses can also protect against the emergence of cataracts.
When a cataract is small or at an early stage, suitable lenses can be fitted over prescription glasses to reduce its impact.
In all cases, the emergence of the pathology requires a change of visual correction.
However, although visual acuity may be improved, this does not mean that cataracts are treated.
Indeed, the eye condition can only be completely and permanently treated by surgery.
Besides, this should be carried out as soon as possible to prevent the pathology from worsening.
Don't hesitate to ask your ophthalmologist or your Optical Center optician for advice if you are affected by cataracts.
