The view is for many the most valuable of the five senses. It is therefore important to take care of it. Cataracts are detrimental to good vision, but fortunately they are easily treated. Do not live in a dull world because of your cataracts: visit your optometrist!
CATARACTS OR DARKENING OF THE LENS
Thousands of images are captured every day by our eyes. We could compare them to small cameras that capture everything around us. Each part of the eye has a specific role to play and their disruption impairs the clarity of vision. The lens, on the other hand, is a small, usually clear, curved disc that is used to direct the light onto the retina, where the images are seen.
However, aging brings about chemical changes in the composition of the lens, which can make it opaque. Cataracts can reach one eye or both. Over time, this cloudy aspect continues to grow if no attention is paid. The ultimate consequence is a complete loss of vision (blindness). Fortunately, if they are well followed, cataracts are rather easy to treat.
This eye disease is quite common and affects people over 50 years of age.
HOW TO RECOGNIZE CATARACTS?
Cataracts are manifested by some characteristic changes in the visual level:
- confused or fuzzy vision;
- colors less clear or duller;
- difficulty in seeing the night well;
- glare more frequent;
- near vision that improves in favor of a decrease in vision from a distance;
- double vision.
If you notice any changes in your vision that resemble these symptoms, consult your optometrist because he or she will be able to do a thorough examination of your eyes. Moreover, an annual visit to this professional eye could detect a cataract from the beginning. This will allow you to act quickly before too much progress.
PREVENTION OF CATARACTS
Certain health problems and lifestyle habits increase the risk of developing cataracts. So, some measures can be put forward to prevent them:
- stop smoking;
- wear sunglasses that block UVA and UVB rays;
- have a diet rich in antioxidants, ie vitamins A, C and E (eg citrus fruits and green vegetables).
In addition, diabetes is an important cause of cataracts. Close control of blood glucose is therefore an asset in their prevention. In addition, some drugs are known to contribute to their development (eg, amiodarone, cortisone, phenytoin).
THE TREATMENT OF CATARACTS
No drug is effective in preventing the progression of cataracts or in treating them. In the earlier stages of lens opacification, your optometrist could only change the prescription of your glasses to improve your eyesight. However, when this adjustment is not enough, he must refer you to an ophthalmologist, the eye doctor. The latter will perform surgery in the eye to replace the deficient lens. This operation takes place when the patient is conscious, because the anesthesia is done only at the level of the operated eye. The success rate of cataract surgery is very high and far vision is much improved.
A period of adaptation is necessary after the surgery:
- The lightening of your lens will make the colors appear very bright and it will dazzle you for some time.
- Avoid driving until your eyesight returns to normal.
- Your optometrist may recommend glasses to improve your eyesight for a few weeks.
- Drops to put in the eyes will be prescribed to you a few weeks after the surgery to decrease the inflammation of your eye and to prevent an infection.
In summary, cataracts reduce the clarity of vision because of the darkening of the lens. This condition is easily treatable by minor surgery at the affected eye. Regular visits to your optometrist are a good way to detect early onset. In addition, the pharmacist will be useful to explain to you how and when to put eye drops that have been prescribed. In short, the treatment of cataracts will restore vigor to the colors around you and life to your daily life.
