The short answer
How do you protect the eye you still have?
Protect it from injury and have it checked regularly. Injury is the most likely threat to a healthy remaining eye, and most eye injuries can be prevented with the right glasses.
Why it matters more now
With two eyes, an injury to one still leaves you seeing. With one eye, the same injury can affect all of your sight. Everyday risks, like a stick while gardening, a splash while cleaning or a stone flying up on a two-wheeler, deserve more respect than before.
Why checks matter even when the eye feels fine
Many eye problems, such as raised pressure inside the eye or early changes at the back of the eye, cause no symptoms at first. Diabetes and high blood pressure affect the eyes too. Regular checks find these while they are easier to treat.
Whether the cancer can affect the other eye
That depends on the cancer. In children with retinoblastoma, a cancer of the back of the eye, the other eye can sometimes be affected and needs close watching. In adults with melanoma inside the eye, the other eye is rarely involved. Your team will explain your own situation.

Changes that need an eye doctor the same day
If your remaining eye suddenly blurs, shows a shower of new floaters, flashes of light or a dark shadow spreading across your view, or becomes painful and red, see an eye doctor the same day. After a chemical splash, rinse with plenty of clean running water straight away, then go. If something sharp has hit the eye, do not rub it or try to pull anything out. Cover it lightly and go straight to an eye emergency service.
Not sure whether this applies to you?
Ask an oncologistEyewear
What kind of eye protection makes sense?
The most important choice is the lens material. Polycarbonate and other impact-resistant lenses resist breaking far better than ordinary lenses.
Everyday glasses
Wear glasses with impact-resistant lenses for most of the day, even if you need no prescription. Clear lenses with no power are available. Ask for sturdy frames that stay on.
Sports goggles
For cricket, badminton, squash, hockey or football, wear goggles made for impact. Ordinary spectacles can break or be pushed into the face by a ball or racket.
Work safety glasses
For welding, grinding, building work, farm work, cleaning with chemicals or any job with flying particles, wear safety glasses or a face shield. Wraparound designs also protect from the side.
Sunglasses and helmets
Good sunglasses cut glare and ultraviolet light. On a two-wheeler, a helmet with a full clear visor keeps out dust, insects and stones.
Check before buying
- Impact-resistant lens material
- Protection against ultraviolet light
- A frame that covers the sides
Follow-up
What eye checks should you expect, and why?
-
After surgery
Your eye surgeon examines the remaining eye as part of follow-up. This is a good time to ask how often it should be checked from now on, and to get that in writing.
-
Children with retinoblastoma
The other eye is examined often, usually under a short anaesthetic in young children, because new tumours can appear in the early years. A genetic test helps decide how closely it needs watching.
-
Adults after melanoma of the eye
Follow-up includes checks elsewhere in the body, often the liver, as well as the socket. The remaining eye is examined routinely, alongside your general eye health.
-
Long term
Regular eye checks look at sharpness, eye pressure and the back of the eye. More frequent checks are needed if you have diabetes, glaucoma in the family or strong short sight.
-
Whenever something changes
Do not wait for the next routine check if your sight changes. Sudden changes need the same-day review described above.

Commonly believed
What do people believe about the remaining eye, and what is true?
"Using the remaining eye too much will damage it."
Reading, screens and fine work do not harm a healthy eye. They can make it feel tired or dry, and breaks, blinking and good light help. Injury and untreated disease are what put it at risk.
"Glasses are only for people with weak sight."
Protective glasses are about safety. Clear, impact-resistant lenses with no power protect a perfectly healthy eye from the everyday knocks and splashes that cause most injuries.
"Rose water or breast milk will soothe a sore eye."
Putting anything unsterile into the eye can cause a serious infection, and with one eye that risk is too high. Use only drops a doctor has advised, and get a sore or red eye checked.
"If the other eye was fine at surgery, it will stay fine."
Most remaining eyes do stay healthy. Ordinary eye conditions still come with age, and after some childhood cancers the other eye needs years of watching. Regular checks find problems early.
Every day
Which everyday habits protect the remaining eye?
- Wear impact-resistant glasses outdoors and for chores
- Put on goggles before cutting grass or using tools
- Keep sharp and pointed objects stored below eye level
- Wear sunglasses in strong sunlight
- Keep blood sugar and blood pressure under control
- Watch firecrackers from a distance, never light them close up
- Wash your hands before touching your eye
- Tell every doctor you see that you have one eye
Rare, but worth knowing
Which rare problems in the remaining eye should you know about?
Serious problems in the remaining eye after a planned eye removal are rare. Knowing the warning signs means you can act early if one does happen.
Inflammation in the other eye
Very rarely, surgery or injury to one eye sets off the immune system against the other eye. This is called sympathetic ophthalmia. It is uncommon after planned eye removal. It shows as pain, redness, discomfort in bright light or blurred sight in the remaining eye, and needs prompt treatment from an eye specialist.
Retinal detachment
The light-sensing layer at the back of the eye can come away. It usually starts with new floaters, flashes or a shadow over part of your view. People with strong short sight are at higher risk. Urgent treatment can often save sight.
What this page cannot tell you
It cannot tell you your own risk, how often your remaining eye should be checked, or whether a change you notice is serious. Your eye doctor answers those after examining you. When in doubt, get it seen.
Questions we are asked
Common questions about protecting the remaining eye
Do I need to wear glasses all the time now?
Wearing impact-resistant glasses for most waking hours is sensible, especially outdoors, while travelling and during chores. They can have clear lenses with no power. Many people take them off at home when resting, and put them back on for any task with a risk.
What lens should I ask the optician for?
Ask for polycarbonate or another impact-resistant lens, in a sturdy frame. These lenses are lighter and much harder to break than ordinary ones. Opticians in Hyderabad and district towns can make them with or without a prescription, and many add ultraviolet protection.
How often should the remaining eye be checked?
Your eye doctor sets the timing. It depends on the cancer you had, your age and conditions such as diabetes or glaucoma. Children with retinoblastoma need very frequent checks early on, and adults usually need regular routine checks. Ask for the schedule in writing.
Can I still play cricket or badminton?
Many people do, wearing sports goggles designed for impact. Ball and racket sports are a common cause of eye injury, so never play without protection. Boxing and other contact sports carry a higher risk. Talk to your eye doctor before you restart any sport.
Is it safe to be around Diwali firecrackers?
Firecrackers cause serious eye injuries every festival season. Watch from a distance, wear protective glasses and do not light them yourself. Keep a child with one eye well back. If a spark reaches the eye, rinse it with clean water and go to an eye emergency service.
Should I stop using my phone to rest my eye?
You do not need to. Screens do not damage the eye, though they can make it feel dry or tired because you blink less. Take short breaks, look at something far away now and then, and use lubricating drops only if your doctor suggests them.
My child had retinoblastoma. Should the brothers and sisters be checked?
Ask your child's team. When retinoblastoma is linked to an inherited gene change, brothers, sisters and future children may need eye checks from birth. A genetic test on your child helps decide who needs them. This matters even if the other children seem to see normally.
Can I use any eye drops for the remaining eye?
Use only drops or medicines a doctor has prescribed for that eye. Some steroid drops can raise the pressure inside the eye when used without supervision. Tell every doctor and pharmacist that you have one eye, so they take extra care with anything that might affect it.
