No, not everyone gets significant cataracts, but it's extremely common with aging; most people develop some degree of clouding, with over half of Americans having them by age 75, and almost everyone experiencing some formation by their 80s, making it a natural part of getting older, though factors like smoking, diabetes, sun exposure, and genetics can speed it up.
Cataracts are most common as people get older, but not everyone will get them. Some people may never have cataracts, while others might develop them sooner. The older you get, the more likely you are to develop cataracts, but it doesn't happen to everyone at the same age.
Better Surgical Outcomes
The best time to have cataracts removed is when they are in the immature stage. At the immature stage, the eye's natural lens is more clouded, and vision changes become noticeable.
No studies have proved how to prevent or slow the growth of cataracts. But health care professionals think several strategies may be helpful, including: Regular eye exams. Eye exams can help detect cataracts and other eye problems at their earliest stages.
The most common age for cataract symptoms to start is after age 60, but they can begin much earlier. Here's a general timeline: Age 40–50: Early signs of lens changes may begin. Symptoms may include changes in the glasses prescription, need for reading glasses, or decreased vision in dim light settings.
Cataract symptoms include: Vision that's cloudy, blurry, foggy or filmy. Changes in the way you see color (colors may look faded or not as vivid). Sensitivity to bright sunlight, headlights or lamps.
Unfortunately, once a cataract has begun to form, there is no way to reverse the process. However, in the early stages, you may be able to manage symptoms through: Updated prescription glasses. Anti-glare sunglasses.
Ageing is the primary reason for the development of cataracts. Over time, the proteins in the eye's lens degrade and clump together, leading to the lens becoming cloudy. This is a natural and progressive process, although there are ways to slow it down.
Scientific studies indicate taking a supplement with at least 300 mg/day of Vitamin C appears to help prevent the development of cataracts. Furthermore, the U.S. Food and Drug Administration recommends that men get a minimum of 90 mg/day of Vitamin C and women get 75 mg/day.
"Ultraviolet light can pass through the eye to the lens and cause cataracts," says Dr. Davis. "So, if you wear sunglasses, you decrease your risk over your lifetime of cataract formation."
Visual problems after cataract surgery
Some people experience some visual disturbances after surgery such as double vision or light sensitivity. In most cases, these improve over time. Blurriness is common immediately after surgery and typically improves within days to weeks after surgery.
NHS waiting times for cataract surgery can vary based on location and hospital capacity. On average: The initial consultation can take 4 to 12 weeks. The waiting time for surgery can range from 3 to 12 months after referral.
Even with a technically perfect outcome after cataract surgery, physicians may find that some patients are unhappy. This dissatisfaction can be due to a number of factors that go beyond visual outcome. Surendra Basti, MD, and Daniel H. Chang, MD, shared what can cause unhappiness and how they discuss it with patients.
While screen time alone does not directly cause cataracts, it can contribute to the overall strain and aging of your eyes. Excessive screen use can lead to symptoms like dry eyes, fatigue, and blurred vision, which may make it harder to notice early signs of cataracts.
Age and Natural Lens Changes
Age is the most common risk factor for cataracts because the natural lens in your eye changes as you get older. While subtle changes can begin as early as age 40, most people do not develop vision-impairing cataracts until after age 60.
Cataracts block vision by clouding and darkening the eye's lens. About 20 percent of people 65 and older people have a cataract. About half of people 75 and older have cataracts.
When your prescription glasses can't clear your vision, the only effective treatment for cataracts is surgery.
Vitamin B2 and vitamin B3 are needed to protect glutathione, an important antioxidant in the eye. Vitamin B2 deficiency has been linked to cataracts. Older people taking 3 mg of vitamin B2 and 40 mg of vitamin B3 per day were partly protected against cataracts in one trial.
What are the most important vitamins for eye health?
While the average age for cataract surgery is around 65–70, many patients undergo the procedure earlier, depending on their needs. The surgery itself is quick, often just 15 minutes per eye, and while cataract surgery recovery may take several weeks, most patients enjoy clearer vision within days.
In fact, in the early stages of cataract development you may not even be aware that you have them. Once cataracts start progressing, the first sign of a cataract will be clouded, blurred or dim vision that causes the appearance of fuzzy spots in your field of vision.
Cataract Risk Factors
Femtosecond Laser-Assisted Surgery
Using femtosecond lasers in cataract surgery has been one of the watershed moments. This mode of operation replaces some manual steps of the procedure with ultra-precise laser pulses, including corneal incisions, lens fragmentation, and capsulotomy (opening of the lens capsule).
Additionally, if you already have cataracts, these vitamins and nutrients may slow their progression.
Early-stage cataracts
Very early cataracts only cause very minor symptoms, and your eyes will almost certainly look clear and normal. You – or anyone else- won't be able to tell that you have a cataract just by looking at you. Most people with early-stage cataracts experience very slight blurriness in their vision.
