Did you know that protecting your eyesight could play a role in preventing dementia?
While it may seem unrelated at first, research increasingly shows that vision health and brain health are closely connected.
Your eyesight might have big implications for your brain.
Vision loss and brain health
Decreased vision can impact brain health by reducing the amount of stimulation that your brain is getting.
When individuals struggle to see clearly, it can lead to reduced engagement in activities that stimulate the mind, such as reading, socializing, or pursuing hobbies.
This lack of mental stimulation, combined with potential social isolation, can increase the risk of dementia.
Studies suggest that vision loss may double the risk of developing dementia.
The good news is, protecting our eyes at any stage of vision can make a difference.
Vision is a key way our brains connect with the world around us, which is why we need to protect our eyes from UV rays.
Protecting your vision
There are several ways to protect your vision and support your brain health in the process:
Wear Sunglasses and Eye Protection
Prolonged UV exposure can damage your eyes over time, increasing the risk of cataracts and other eye conditions.
Wearing sunglasses with UV protection shields your eyes from harmful rays and helps preserve long-term eye health.
Looks cool AND good for your health? That’s a win-win.
Schedule Regular Eye Exams
Routine eye check-ups can detect and address vision problems early, such as cataracts, glaucoma, or macular degeneration. Correcting vision issues with glasses, contact lenses, or surgery can help maintain your quality of life and brain health.
E…F…P… test your eyes at the ophthalmologist every few years (and every year if you’re diabetic!)
Maintain a Vision-Friendly Diet
Foods rich in antioxidants, such as leafy greens, carrots, and omega-3 fatty acids from fish, support eye health and reduce the risk of conditions like age-related macular degeneration.
Good news - the MIND diet incorporates these nutrients, so you only need to follow one nutrition plan.
Follow the MIND diet for brain health and eye health.
Stay Mentally and Socially Active
Even if you develop vision problems, continue to stay socially engaged. An active social life is a key way to maintain your brain health at any age.
Groups like CNIB have great tips and tricks for managing changes to your vision, including advice on technology that can keep you connected.
In Closing…
By taking steps to care for your eyesight, you not only improve your vision but also your long-term brain health.
Schedule that eye exam today and make simple lifestyle changes to protect your eyesight for years to come.
