Summary
Overview
Drs Chris and Xand van Tulleken explore eye health with consultant ophthalmic surgeon Mr Raj Dasbomik from Moorfields Eye Hospital. They discuss why regular eye tests are crucial (not just for vision, but for detecting serious conditions), what happens during an eye exam, warning signs never to ignore, and debunk common myths about eye exercises and glasses. The episode emphasizes that 50% of sight loss is avoidable with proper eye care.
Why Eye Tests Matter Beyond Vision
Chris admits he's never had an eye test as an adult, relying on reading glasses bought at an airport. Raj explains that while poor vision and eye health are separate issues, regular eye tests are essential for detecting serious conditions like glaucoma, macular degeneration, and even cancer before they cause irreversible damage. The eye test isn't really about whether you need glasses - it's about using the eyes as a window to overall health and catching treatable conditions early.
- NHS recommends eye tests every two years - Chris is approximately 22 tests behind at age 47
- Two million people in the UK live with sight loss, expected to rise to 2.7 million by 2030
- 50% of sight loss is avoidable with proper detection and treatment
- Eye tests detect serious conditions like glaucoma, macular degeneration, diabetic eye disease, and cancer - not just vision problems
" I'm not horrified, because it is really, really common. There are people that just don't go and have their eyes tested, and it's bonkers, and I'll tell you why it's bonkers. "
" You can have poor vision and still have very healthy eyes and you can have very good vision and have major eye problems. That's why you go to the eye test. "
What Actually Happens During an Eye Test
Raj walks through the modern eye test process to demystify it for nervous patients. Beyond the standard vision chart, optometrists check color vision (an indicator of optic nerve health), measure eye pressure for glaucoma screening, and often take high-resolution retinal images and scans. The process is non-invasive, with pressure checks done via a simple puff of air, making it far less intimidating than many people fear.
- Standard tests include vision charts, near reading assessment, and color vision checks (red color appreciation indicates optic nerve health)
- Eye pressure is checked non-invasively with a puff of air to screen for glaucoma
- Modern tests include retinal imaging, optic nerve scans, and macular assessments to detect conditions early
- Optometrists can diagnose numerous conditions beyond eye health - 'you name a disease, I could probably find something in the eyes that reflect that disease'
" Picking up changes in the retina from say diabetes or high blood pressure absolutely crucial because it can save your life. "
