Sunglasses to prevent cataracts

Can wearing sunglasses prevent cataracts?

The eyes are extremely fragile and need to be protected from any possible external aggression.
Sunglasses are known to provide them with effective protection against strong ultraviolet rays.
Wearing sunglasses is definitely beneficial, but can it also prevent cataracts?

The development of cataracts and prevention means

Cataracts are an ocular pathology directly linked to the ageing of the crystalline lens.
In this case, the normally transparent lens behind the iris becomes partially or totally opaque.
As a result, vision is affected by a drop in acuity and discomfort with light.
The effects of cataracts generally set in gradually and exponentially.
It is therefore essential to treat this condition as soon as possible once it has been detected, which can be done through surgery.
Cataracts are associated with advancing age, and particularly affect people who are severely short-sighted or have DMLA or glaucoma.
Certain factors, such as smoking, alcohol, diabetes and a poor diet, can encourage the onset of the condition.
It is therefore advisable to maintain a healthy lifestyle and have your eyesight checked regularly as a preventive measure.

How do sunglasses help prevent cataracts?

As we have seen, cataracts are essentially caused by the natural ageing of the crystalline lens.
However, this disease can be advanced or aggravated by excessive exposure to ultraviolet rays.
Wearing sunglasses can help reduce the impact of the sun's strong rays on the eyes.
By doing so, they reduce the risk of cataracts appearing, or can prevent them worsening.
To be effective, sunglasses should be fitted with 3 or 4 index lenses.
Regular eye protection with a suitable pair of sunglasses can therefore have a real impact in the prevention of cataracts.
It should be noted that after cataract surgery, sunglasses are also required to protect the newly treated eyes.
