Yes, cataract surgery improves your night vision to a larger extent. Night vision improvement will enable you to drive, walk in low lights too. As the cataract advances the vision loss worsens, surgery might help restore your vision back.
Glare, halos and other unwanted images
Many cataract patients experience “unwanted visual images” after surgery, also known as dyphotopsia. Glare, halos and streaks of light are examples of positive dysphotopsia. They occur more frequently at night or in dim lighting, and are more common with multifocal lenses.
The consensus seems to be that it takes 1-3 months.
There is no question, if you want the best possible night vision, then a monofocal lens is your best option (Figure A), but you must be willing to use over-the-counter reading glasses.
Cataract patients with poor night vision (or night blindness) have trouble seeing in dim light or darkness. This means the eyes take a very long time to adjust when going from light to dark. Patients experiencing this cataract symptom struggle in low light conditions such as driving at night and in cinemas.
Treatment for Night Blindness
Treatments range from simply purchasing a special pair of glasses, lens coatings or contact lenses to wear at night (for optical issues such as myopia) to surgery (to correct the underlying problem such as cataracts), to medication (for diseases like glaucoma).
Why Is Driving at Night Difficult? If you struggle to see clearly at night when driving or navigating your house, you may have night blindness (nyctalopia). You have night blindness when you struggle to see at night or in dimly lit areas. It may take longer for your eyes to adapt to darker environments.
A posterior subcapsular cataract often interferes with your reading vision, reduces your vision in bright light, and causes glare or halos around lights at night. These types of cataracts tend to progress faster than other types do.
Cataracts can make it difficult to see in low light. One of the primary indications that cataracts are developing is the gradual loss of contrast sensitivity, which becomes especially noticeable in dim lighting. This can heavily impact night vision, making activities like driving difficult or even dangerous.
You can continue to drive if you have a cataract, provided you meet the standards of vision for driving and do not experience visually significant glare. However, if you have been diagnosed with cataract, surgery to remove your cataract will almost certainly improve the quality of your vision.
Anisometropia is another way of describing an imbalance between the two eyes. This can sometimes happen following surgery, as your brain tries to adjust to the changes in your vision. Cataract surgery involves replacing the natural lens of your eye with an artificial one.
Medicare will pay for one pair of post-cataract surgery glasses per lifetime per eye after cataract surgery.
So How Long is Vision Blurry After Cataract Surgery? Most people will see improvement within 24-48 hours after cataract laser surgery, although it can take up to two weeks for your eyes to fully settle to the new implants. Most patients are back to normal activities the next day.
Yes, after cataract surgery, you need to wear sunglasses to protect your eyes from the sun. After surgery, your eyes are healing and are more sensitive to the sun's rays than usual.
Protective glasses are prescribed after cataract surgery. But for the purpose of reading, you can use your old glasses for up to 3 weeks until the refractive power of the operated eye stabilises, after which your doctor will prescribe new glasses.
These side effects usually improve within a few days, but it can take 4 to 6 weeks to recover fully. If you need new glasses, you will not be able to order them until your eye has completely healed, usually after 6 weeks.

Treatments range from simply purchasing a special pair of glasses, lens coatings or contact lenses to wear at night (for optical issues such as myopia) to surgery (to correct the underlying problem such as cataracts), to medication (for diseases like glaucoma).
At night, and other low light situations, your pupil dilates (gets larger) to allow in more light. When this happens, more peripheral light enters your eye. This causes more blurring and glare, and makes lights look fuzzier.
People with dark brown eyes have the greatest risk of developing cataracts. An Australian study found that the risk can be up to 2.5 times greater for certain types of cataracts. Researchers suspect the reason is similar to wearing a black shirt in the middle of summer.
If left untreated, cataracts can eventually lead to blindness. Many people assume that cataract surgery will give them "perfect" 20/20 vision, but this isn't always the case. In fact, some people may still need glasses or contacts to see clearly after surgery. But this doesn't mean the procedure isn't worth it!.
UV light can cause cataracts to progress faster than they otherwise would. While it would not be healthy to avoid all exposure to the sun, it's best to avoid going out when the glare is brightest and the UV light is strongest—from 10 am to 4 pm most of the year, and from 11 am to 3 pm during daylight savings time.
Aging Only Makes Night Driving Harder
The older we get, the worse our night vision becomes. That's because we gradually lose some of the rods in our eyes (specialized cells that distinguish between light and dark).
Do's and Don'ts of driving at night with cataracts
For example, avoid driving west at dusk or during an evening rainstorm. Clean the inside and outside of both your front and rear windshields often to give your eyes a helping hand. It's important to do everything you can to ensure you can see clearly.
The eye takes approximately 20–30 minutes to fully adapt from bright sunlight to complete darkness and becomes 10,000 to 1,000,000 times more sensitive than at full daylight.
