The clouding of the normally clear eye’s lens is called a cataract. Seeing through hazy lenses is like gazing through a foggy or icy window for those who have cataracts. Cataract-related vision impairment might make it more challenging to read, drive at night, or read a friend’s face. Early on, the majority of cataracts do not impair vision since they develop gradually. Cataracts, however, will eventually impair eyesight.
First, cataracts can be treated with better lighting and spectacles. However, cataract surgery may be required if normal activities are impeded by vision impairment. Thankfully, cataract surgery is typically a successful and safe treatment.
Cataract Types
Can take many different forms. Types consist of:
- Cataracts in children: Children and infants are affected by pediatric cataracts. Congenital cataracts can develop in babies from birth, or they can develop later in life. Although they usually run in families, periodic cataracts can sometimes result from eye trauma and other eye Disorders. Pediatric cataracts in infants and kids must be treated right away to avoid issues like amblyopia, or lazy eye.
- Cataracts caused by trauma: When your eye is injured, these cataracts develop. The structures surrounding the lens may also need to be repaired. Treatment for this type is more complex.
- Cataracts that develop later: These hazy areas that develop on the membrane that surrounds your lens. Also known as the lens capsule. This syndrome is also known as posterior capsular opacification. It is a frequent but manageable side effect of cataract surgery.
Why do cataracts occur?
The most frequent cause is aging. This is caused by typical eye changes that start to occur after age 40. At that point, the lens’s regular proteins begin to degrade. This is the reason why the lens becomes foggy. Typically, people over 60 begin to experience some clouding of their lenses. On the other hand, visual issues cannot appear for years.
You may also develop cataracts for the following reasons:
- Smoking and spending a lot of time in the sun, particularly without sunglasses that shield your eyes from UV radiation.
- Using some drugs like corticosteroids while suffering from certain illnesses like diabetes can result in the early development of cataracts.
- Having undergone upper body radiation therapy, eye surgery, or an eye injury.
- Having family members with cataracts, such as parents, siblings, or grandparents.
The majority of age-related cataracts appear gradually. Other cataracts, such as those in younger individuals or those with diabetes, may develop more quickly. The rate at which a person’s cataract may develop is unpredictable to doctors.
Symptoms of cataracts
Symptoms of cataracts include:
- Misty, hazy, foggy, or filmy vision
- Alterations in your perception of colour may cause colours to appear less vibrant or faded.
- Sensitivity to bulbs, headlights, or intense sunlight.
- Glare, which includes streaks or halos that develop around lights.
- Difficulty in nighttime visibility.
- Alterations to your prescription for vision, such as worsening nearsightedness.
- Reading requires a brighter light.
- Double vision
Tests
The following test may be used to detect cataracts:
- Slit lamp Exam: The front portions of your eye are closely examined using a specialised microscope.
- Visual acuity test: To gauge your vision at various distances, you will read letters on a chart.
- Dilated retinal exam: Your ophthalmologist will dilate your pupils with eye drops while attentively examining the retina and lens for indications of cataracts or other eye issues.
Ways to avoid cataracts
You can delay or avoid cataract development with a little luck and the appropriate preventive measures. The following are some tried and true methods to assist you in safeguarding your vision:
- Defend your eyes from UV light
- Keep your diet healthy
- Avoid alcohol and tobacco
- Control long-term medical conditions
- Minimise your exposure to dangerous substances
- Maintain good eye hygiene
- Maintain your physical activity level
- Limit extended use of screen time
When to consult the doctor?
If you observe any changes in your eyesight, schedule an eye test. See a member of your health care team immediately if you experience any abrupt changes in your vision, such as double vision, light flashes, acute eye pain, or unexpected headache.
The function of frequent eye exams
Regular eye exams are essential for maintaining eye health and avoiding cataracts. In addition to checking your vision, these examinations protect your eyesight and detect problems early on, frequently before you have any symptoms. For many of them, this could mean the difference between continuing to have decent vision and suffering from harsher consequences later on.
