Most people assume myopia is purely a childhood condition something you develop young and then manage with glasses forever. But myopia in adults is more complex than that. Prescriptions can continue changing well into the twenties and sometimes beyond. Work patterns involving prolonged computer use, late nights, and reduced outdoor exposure all contribute. At The Eye Foundation, we regularly see adults whose short-sightedness has been steadily worsening for years and who didn't realise there were options beyond simply updating their glasses. This blog explains what's happening, why it matters, and what you can do about it.
Why Does Myopia Progress in Adults?
For most people, myopia stabilises somewhere in the mid-to-late twenties. But for a significant proportion particularly those in professions involving intensive near work the prescription continues to creep upward.
A few reasons this happens:
- Extended near work: Software developers, writers, surgeons, and others who spend eight-plus hours focused on screens or close tasks are at higher risk of continued progression
- Reduced outdoor exposure: Adults in urban environments often spend very little time in natural light
- Inadequate correction: Wearing an outdated prescription can actually strain the eyes further
- Underlying health conditions: Conditions like diabetes can affect lens shape and contribute to prescription changes
The Risks of High Myopia
This is the part most people aren't told clearly enough. Myopia isn't just an inconvenience at higher levels it becomes a genuine risk factor for serious eye disease.
Adults with high myopia (typically above -6.00 dioptres) face elevated risks of:
- Retinal detachment the retina is stretched thinner in a myopic eye and more prone to tearing
- Glaucoma increased intraocular pressure risk
- Myopic macular degeneration damage to the central retina that can affect detailed vision
- Early cataracts Regular monitoring at The Eye Foundation allows these risks to be identified and managed before they become serious problems.
Treatment Options for Adults With Myopia
The Eye Foundation offers the full spectrum of treatment for myopia in adults:
Updated spectacles and contact lenses: Always the first step wearing the correct prescription matters more than most people realise
- LASIK laser surgery: For adults with a stable prescription, LASIK for myopia offers permanent correction with a high success rate and fast recovery. Most patients see clearly within 24 hours
- SMILE procedure: A newer, flapless laser technique that's particularly suitable for patients with dry eyes or active lifestyles
- ICL (mplantable Collamer Lens)I: For patients whose prescription is too high for laser surgery, an ICL is implanted inside the eye to provide correction without removing corneal tissue
Regular monitoring: For patients not yet ready for surgery, structured annual reviews track progression and catch complications early
- Lifestyle Changes That Help
- Even as an adult, lifestyle matters:
- Protect your eyes with UV-blocking sunglasses outdoors
- Follow the 20-20-20 rule during work hours
- Ensure your workstation lighting is adequate
- Get annual dilated eye exams not just a quick prescription check

FAQ’S
1.What causes myopia to worsen in adults?
Prolonged near work, reduced outdoor time, and insufficient correction are the main culprits.
2.When should an adult be concerned about changing myopia?
Any change in prescription year on year warrants a thorough evaluation. Changes above 0.50 dioptres per year are considered significant and should be investigated at a centre like The Eye Foundation.
3.How is myopia treated permanently in adults?
The main options for permanent correction are LASIK, SMILE and ICL implants. What’s right for you depends on your prescription, corneal thickness and lifestyle – a detailed assessment at The Eye Foundation will tell you which suits you best.
4.Who is a good candidate for LASIK?
Patients over 18 years of age with a stable prescription for at least one to two years, adequate corneal thickness and no significant dry eye problems are generally good candidates for LASIK for myopia.
The Eye Foundation has a provider of LASIK and advanced myopia treatment. The Eye Foundation’s refractive surgery team is made up of experienced corneal and refractive specialists who perform hundreds of procedures each year with a high level of precision and safety.
