About Sornthai

65 years of outstanding care


Outstanding
Primary Eye Care


Sornthai Bangkok optometrist proudly provides essential primary eye care to children and adults. Our comprehensive eye examinations go beyond the norm of just measuring visual acuity or clarity of vision. Let’s take a look at the different tests we run for our patients.

Vision Acuity Test

We determine the correct lens prescription for your eyes using a computer-controlled auto refractor for objective refraction, followed by a subjective refraction exam for accuracy.

Non-Invasive Tonometry

Our non-contact tonomete measures the fluid pressure inside your eyes without the need for numbing eyedrops. This procedure detects risk for glaucoma and intraocular infections.

Contact Lens Fitting

Choosing contacts that perfectly fit the curve of your eyes lessens symptoms of eye discomfort, eye strain, and dry eyes. This keeps your eyes healthy even with regular contact lens wear.

Binocular Vision Assessment

Diagnose amblyopia (lazy eye), strabismus (turned eye), as well as phoria (eyes misaligned when fusion is broken)—one of the most common causes of eye discomfort that fly by undetected. Phoria hinders development and the ability to read and learn, making this exam crucial for every child under 12 and those with learning difficulties.

Corneal Topography

Our Center offers 360-degree corneal mapping for keratoconus screening, contact lens fitting, and post-operative care after LASIK, pterygium surgery, corneal transplant, and other eye surgeries.

Colorblindness Test & Analysis

For high accuracy colorblindness testing, we use the Ishihara Test to detect the condition and the Farnsworth D-15 to diagnose the type and quantity (severity) of the deficiency.

Extensive Behavioral Eye Exam

Assess the level of visual perception, visual analysis, the eyes’ ability to quickly and accurately shift attention from one object to another, the understanding of laterality (right-left), body awareness, spatial awareness, and peripheral awareness, to enhance skills required in reading, learning, sports and playing musical instruments.

Biomicroscopy

A detailed assessment of the anterior (frontal) eye. During your biomicroscopy, we examine your eyelids, eyelashes, ocular mucous membrane, corneal, iris, and crystalline lenses to find conditions like cataracts, dry eyes, eyelid bumps, corneal swelling, and eye infections.

Ophthalmoscopy

Using a Fundus Camera, we photograph the back of your eyes for a posterior eye assessment. We examine your retina, optic disc, and blood vessels to detect conditions like glaucoma, macular degeneration, embolisms, and diabetic retinopathy.

Low Vision Exam & Analysis

Some vision problems unfortunately can’t be corrected, nor treated. When glasses, contact lenses, medicine, and surgery don’t work, Sornthai’s compassionate and practical approach tailored to the individual ensures an improved quality of life.

Children's Eye Center

Sornthai Children’s
Eye Center
For Brighter Futures

Children learn through their eyes. That’s why healthy vision is crucial for development—and we don’t mean just seeing 20/20! Sornthai helps prepare your little one as they discover a world of limitless learning. Bright eyes that see and read effortlessly open up a world of possibilities.

Boost learning skills with vision therapy (ACBO Australia)

25% of all children have binocular vision problems, where their eyes struggle to work together as a team. This causes eyestrain, double vision, nausea, and headaches, and is often mistaken for clumsiness, laziness, learning disorders or ADD/ADHD. ACBO Australia’s vision therapy programs at Sornthai help children see comfortably and efficiently, for enhanced memory, reading comprehension, confidence, and overall learning experience.
