TL;DR
While cataract surgery is the only way to remove them completely, there are several effective ways to slow their growth and protect your sight.
By taking action early and making healthy lifestyle choices, you can give yourself the best chance of keeping your vision clear for longer. Keep reading to discover practical steps you can take to stop cataracts from worsening.
Protect your eyes from UV light
Long-term exposure to ultraviolet (UV) light damages the proteins in your eye’s lens, which can speed up cataract formation. The simplest way to protect yourself is to wear sunglasses that block 100% of UVA and UVB rays. Look for a pair with a label confirming full UV protection.
Pairing sunglasses with a wide-brimmed hat gives you extra shade and reduces glare, especially in the middle of the day. Remember, UV rays are present even on overcast days, so eye protection is important all year round, not just in summer.
Maintain a healthy diet
Your diet plays an important role in eye health. Antioxidants such as vitamins C and E help protect your eyes from oxidative stress, which contributes to cataract growth. Eating foods like oranges, strawberries, red peppers, almonds, sunflower seeds, spinach, and kale can give you a good supply of these nutrients.
Zinc, found in beans, lentils, and pumpkin seeds, also supports healthy eyes. Omega-3 fatty acids, which are abundant in oily fish such as salmon, sardines, and mackerel, can reduce inflammation and improve general eye function. Eating a variety of fresh, unprocessed foods is a powerful way to support your sight.
Quit smoking
Smoking increases oxidative damage in the lens and reduces the amount of protective antioxidants in your body. It has been shown to both cause cataracts and speed up their development.
If you smoke, stopping now can slow down the progression and reduce your risk of other serious eye conditions, such as macular degeneration.
Quitting can be challenging, but there is help available. You can speak to your GP, access local NHS stop-smoking services, or try nicotine replacement therapies. Every smoke-free day gives your eyes a better chance of staying healthy.
Limit alcohol consumption
Drinking large amounts of alcohol can harm the delicate structures in your eyes and increase cataract risk. Heavy drinking has been linked to higher rates of lens clouding, while keeping your alcohol intake low can help protect your vision.
The NHS recommends no more than 14 units of alcohol a week, spread over several days. That is roughly six pints of average-strength beer or six medium glasses of wine. Cutting down, or swapping some drinks for water or soft alternatives, supports not just your eyes but your overall health.
Manage underlying health conditions
Health conditions such as diabetes, high blood pressure, and obesity can make cataracts progress faster. High blood sugar can alter the proteins in your eye lens, while high blood pressure can affect blood flow to your eyes. Managing these conditions is key to slowing down any vision loss.
Attend regular medical check-ups, follow your prescribed treatment plan, and make lifestyle changes recommended by your healthcare provider. For example, if you have diabetes, aim to keep your blood sugar within your target range through a healthy diet, physical activity, and medication if required.
Have regular eye examinations
An optometrist can detect cataract changes early, even before you notice symptoms. This allows you to make timely adjustments to your lifestyle and plan for treatment if needed.
People over 60 can have free NHS eye tests, and others may qualify depending on health status or family history. During an eye test, your optometrist will check the clarity of your lens and look for any other eye problems. Regular checks help you keep track of any changes and respond quickly.
Reduce eye strain
Although eye strain does not cause cataracts, it can make living with them more uncomfortable. Poor lighting, glare, and extended screen use can all make vision tasks harder.
To reduce strain, use bright but non-glare lighting for reading or detailed work. Adjust your computer or phone brightness to a comfortable level, and follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. This helps to relax the muscles in your eyes and reduce fatigue.
Stay physically active
Exercise promotes good circulation and oxygen flow throughout your body, including your eyes. It also helps control weight, blood pressure, and blood sugar, all of which are linked to cataract progression.
Aim for at least 150 minutes of moderate-intensity exercise a week, such as brisk walking, cycling, or swimming. You can also add strength training twice a week to support your overall health. If you are new to exercise, start gradually and build up over time.
Avoid eye injuries
An injury to your eye can trigger cataract formation or make existing ones worse. Protecting your eyes is especially important if you take part in sports, DIY projects, or work in environments with flying debris.
Wear safety goggles or sports-specific eyewear to shield your eyes from potential harm. These are widely available from hardware shops, sports stores, and online retailers, and they can prevent injuries that might otherwise lead to serious vision problems.
It can be possible to slow the growth of cataracts
You may not be able to prevent cataracts completely, but you can slow their growth through consistent, healthy choices. Wearing UV-blocking sunglasses, eating a nutrient-rich diet, keeping medical conditions under control, and having regular eye exams all make a difference.
It is also important to listen to your body and act when you notice changes in your vision. The earlier you address problems, the more options you have to maintain your sight and quality of life. By combining these steps, you can protect your eyes and continue enjoying activities that matter to you for as long as possible.
