As we age, our bodies undergo many changes, and our eyes are no exception. Many eye conditions are directly linked to aging, and can affect our vision in different ways. By understanding these changes, we can better prevent them, and adopt the right habits to preserve the health of our eyes.
The main age-related visual changes
Presbyopia: the loss of near vision. Presbyopia is one of the first signs of eye aging. Around the age of 40-45, the crystalline lens loses its elasticity, making it more difficult to focus on close-up objects. This is why many people begin to need reading glasses or progressive lenses.
Dry eyes: With age, tear production declines, which can lead to dry eyes. Symptoms include irritated eyes, a burning sensation and fluctuating vision. The use of artificial tears and proper hydration can help alleviate this discomfort.
The onset of cataracts: Cataracts occur between the ages of 65 and 70. They result from progressive opacification of the crystalline lens, leading to blurred vision, increased sensitivity to light and difficulty in perceiving contrasts. Fortunately, cataract surgery is a common and effective procedure.
Increased risk of age-related macular degeneration (AMD): AMD is a disease of the retina that can lead to progressive loss of central vision. It manifests itself as distorted vision or blurred areas in the center of the visual field. Regular screening and a diet rich in antioxidants can help slow its progression.
Glaucoma and intraocular pressure: Glaucoma is a disease that affects the optic nerve and can lead to irreversible vision loss if not detected early. It is often associated with high intraocular pressure. Regular check-ups with an optometrist are essential to detect this condition early.
How can we protect our vision as we age?
- Consult an optometrist regularly to detect any anomalies as soon as they appear.
- Eat a diet rich in eye-friendly nutrients such as omega-3, vitamins C and E, and lutein.
- Wear sunglasses to protect your eyes from UV rays, which accelerate eye aging.
- Maintain good visual hygiene, by limiting screen time and taking regular breaks during activities that place heavy demands on the eyes.
- Avoid tobacco, which is a major risk factor for AMD and other eye diseases.
Although vision aging is inevitable, it is possible to slow its impact by adopting good habits and consulting an optometrist regularly. Take care of your eyes - they'll be with you for life!
