The age of 40 may bring along physical changes, including changes to your vision. For example, if you find yourself holding your phone farther away to read messages, struggling to read menus in low light or having difficulty focusing on nearby objects, there is nothing unusual about it.
Of course, certain vision changes happen naturally with age. However, experts advise against ignoring them. There are several ways to help preserve your vision in the future, such as getting your eyes checked regularly and adopting a few healthy habits, according to Dr Mandeep Singh Basu, Director, Jagat Pharma. The key to maintaining healthy vision after 40 lies in understanding these changes.
Why does eyesight change after 40?
One of the most common age-related eye changes is presbyopia, a condition in which the eye's natural lens gradually becomes less flexible, making it difficult to focus on nearby objects. As a result, many people need reading glasses or bifocals for the first time in their 40s.
Although presbyopia is considered a normal part of ageing, this stage of life also brings an increased risk of several eye diseases.
Eye conditions that become more common after 40
According to Dr Basu, the risk of the following conditions starts increasing after the age of 40:
- Cataracts, which gradually cloud the eye's lens and reduce vision clarity.
- Glaucoma, a group of eye diseases that damage the optic nerve and often develop without noticeable early symptoms.
- Diabetic retinopathy, caused by damage to the retina's blood vessels, particularly in people living with diabetes.
- Age-related macular degeneration (AMD), which affects the central part of the retina and may impact detailed vision later in life.
7 simple habits to protect your eyesight
1. Schedule regular eye examinations
Comprehensive dilated eye examinations can detect glaucoma, diabetic eye disease and other vision problems before symptoms appear. Eye care professionals generally recommend getting your eyes checked every one to two years after turning 40.
2. Follow the 20-20-20 rule
If you spend long hours using digital devices, remember the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds. This simple habit helps reduce digital eye strain.
3. Choose foods that support eye health
Proper nutrition also plays an important role in maintaining healthy vision. According to Dr Basu, you should consume leafy greens, colourful fruits and vegetables, fish rich in omega-3 fatty acids, and foods containing lutein and zeaxanthin.
4. Wear protective sunglasses
Sunglasses that block both UVA and UVB rays help protect your eyes from harmful sunlight and may reduce the risk of developing cataracts.
5. Monitor your health conditions
Conditions such as diabetes, high blood pressure and high cholesterol can negatively affect eye health. Therefore, it is important to keep these conditions under control.
6. Stay hydrated and prevent dry eyes
Dry air and prolonged screen time can cause eye irritation and dryness. Staying hydrated and consciously blinking more often can help relieve discomfort.
7. Don't delay visiting an eye doctor
If you experience blurred vision, flashes of light, floaters or eye pain, do not wait until your next routine appointment. Consult an eye specialist immediately.
Looking after your eyes is an investment in the future
Age-related vision changes are a natural part of ageing, but many serious eye conditions can be detected early and treated successfully. Regular eye examinations, a healthy diet, protection from UV rays and healthy screen habits can all help preserve your vision.
When you turn 40, taking care of your eye health isn't just about seeing clearly today. It is an investment in maintaining good vision for the years ahead.
