Don’t be afraid of the trouble of getting your eyes tested and glasses fitted, regular hospitals are the most reliable!

When you walk into the ophthalmology department of a hospital and face the numerous examination items, have you ever wondered: "I just come here to get a pair of glasses, why do I have to do so many tests?" Or maybe you are muttering in your heart: "Isn't it enough to just test the degree, why is it so cumbersome?" Don't worry, the following will answer these questions for you in detail.

The examinations required for adults to wear glasses include pupil distance measurement, computer optometry, and subjective optometry. In order to assess eye health and ensure the safety of glasses, the hospital will conduct intraocular pressure examinations and basic ophthalmological examinations in addition to general glasses examinations.

In simple terms, the pupil distance is the distance between the black pupils of the eyes when they are looking straight ahead. This distance is very important and must be measured accurately when fitting glasses so that the center of the lens power can perfectly correspond to the center of your eye, allowing you to see things without fatigue and with clear vision.

Computer optometry can be understood as an advanced vision examination tool. This efficient and intuitive examination can quickly assess your vision condition, provide doctors with a reliable degree range, provide preliminary data for the next step of subjective optometry, and improve the efficiency of glasses fitting.

Subjective refraction is a personalized adjustment process for vision testing. Just like a tailor sewing a piece of clothing that fits you well, by trying on different lenses and looking at the eye chart, the doctor will gradually fine-tune your vision to the clearest and most comfortable state based on your feedback. It is different from automatic detection by machines and relies more on your subjective feelings. During the doctor's further examination and communication with you, the doctor will fit the lens power that best suits your daily work and life needs.

Intraocular pressure measurement mainly checks the "pressure value" inside the eyeball. If the eyeball is compared to a balloon, then intraocular pressure is like the "internal air pressure" that maintains its shape. When the "air pressure" is too high, just like a balloon is over-inflated, the eyeball will sound an alarm - it may induce eye diseases such as glaucoma; conversely, insufficient "air pressure" can also hide hidden dangers and affect eye health. Intraocular pressure measurement during professional fitting can help to detect and intervene in high intraocular pressure symptoms in the eye at an early stage, and protect our window to vision.

The basic ophthalmological examination is a "physical examination" of the eyes. During this process, the doctor will use instruments such as a slit lamp to examine the basic structure of the eye and screen for eye diseases. Many eye diseases are discovered through this examination.

The process of glasses fitting examination in the hospital may seem cumbersome, but in fact, these examination items have their unique significance and role. They can not only help doctors understand your eye condition more accurately, but also ensure the accuracy and comfort of glasses fitting, thus giving you a better visual experience.
