Sonya Wijaya

Sonya Wijaya


Our principal optometrist, Sonya Wijaya, has over fifteen years of experience in optometry, examining eyes and providing solutions to eye problems. Sonya started working in optics in 2004 while doing her final two years in her optometry degree. She graduated from The University of Melbourne in 2006 with therapeutic endorsement.

Sonya was working alongside leading researchers and clinicians in the field at the State University of New York as part of her clinical placement. She was working in regional Victoria and South Australia for two years to challenge herself in understanding complex ocular pathologies and diseases. She loved the challenges and opportunities present in rural practices.

In 2009, Sonya obtained Optical In Sight Donvale and dedicated herself to providing eye care consistently in one practice. She is very proactive in providing the highest level of eye care, and contributes to the community and profession. She has excellent relationships with local GPs, ophthalmologists, and other allied health professionals.

She also developed a special interest in children’s optometry services as she loves working with children, being a mother herself. An organisation she closely supports is UNICEF. UNICEF proactively helps children in crisis throughout the world. She is actively presenting in local early learning centres and schools to promote the importance of eye health. Aside from optometry, she enjoys the arts as she was an accomplished artist at an international level before she decided to be an optometrist.
