与您的医疗保健提供者一起确定适合您的合适解决方案。.
验光师会进行眼科检查，以评估您的眼睛整体健康状况，并为您开具隐形眼镜、眼镜或低视力辅助设备的处方。验光师会进行多项检查，包括视力（您远近视力如何）、辨色能力、深度知觉、视网膜健康状况、眼压等等。验光师可能会使用散瞳眼药水，以帮助检测青光眼、白内障、黄斑变性等眼部疾病。.
眼科医生是专门从事眼部健康及相关疾病的医学博士。眼科医生需接受研究生培训，才能具备治疗眼部疾病的资质，包括药物治疗和手术治疗。眼科医生为常见的眼部问题（例如白内障）提供手术解决方案，并监测青光眼等眼部疾病，同时还能进行激光矫正手术。.

Cosmetic contact lenses or colored contact lenses may seem harmless but can lead to severe eye problems or loss of vision if not fit by an eye specialist. You need to have a prescription for contact lenses as they are deemed medical devices by the U.S. Food and Drug Administration (FDA). Non- prescription contacts can create problems due to issues such as poor fitting or unclean packing/creation.
When contact lenses not specifically fitted and sized for your eyes are worn, the cornea may be scratched, potentially leading to the following:
Eye infections are also very common in non-prescribed contact lenses and may lead to the following:
Discussing your options and proper contact lenses hygiene with an eye care professional, having the
proper measurements of your eyes taken, and getting a valid prescription is an easy way to avoid these
potentially life changing complications.

Your visual field refers to the area in which you can see objects in all directions as you focus on a single central point. This test of your peripheral vision is simple, painless, and vital in diagnosing and tracking the progress of health conditions.
Confrontational Visual Field Test: The patient looks at an object in front of them with one eye covered. While looking at this object the patient will be asked how many fingers they see the doctor holding up in the patient’s periphery.

Automated static perimetry test: The patient looks in the center of a bowl-shaped instrument called a perimeter. Lenses are placed in front of the patient’s tested eye while the other is covered with an eye patch. While looking at the center target, several flashes of light will appear in the patient’s periphery at which point they will use a clicker to indicate when they see them.

Kinetic visual field test: Similar to above but now moving light targets are used instead of blinking lights.
Visual fields can be helpful in diagnosing, treatment plans for, and monitoring various conditions such
as:
Depending on your situation you may be recommended to take a visual field test again in a few weeks, a
few months, or a year.
几乎每个人都会过度使用电子屏幕，因此出现与电子产品相关的眼疲劳和酸胀症状非常普遍；这种情况被称为电脑视觉综合征（CVS）或数码眼疲劳。顾名思义，长时间阅读或盯着电子设备屏幕会导致眼睛疲劳。电脑视觉综合征的一些常见症状包括眼疲劳、头痛、眼睛干涩、颈部疼痛以及视力逐渐模糊。.
既然我们作为验光师无法要求患者完全避免使用电脑或长时间盯着屏幕，那么有哪些方法可以缓解电脑视觉综合征（CVS）的症状并避免病情加重呢？检查办公桌或工作台的照明和工作距离是否合适会有所帮助。此外，全天注意保持正确的姿势也很重要，并确保佩戴合适的视力矫正设备，例如眼镜或隐形眼镜，以避免进一步的眼疲劳。.
避免眼睛疲劳的小贴士
遵循这些简单的建议，不仅可以改善您的眼睛感觉，而且自然而然地提高您全天的工作效率、生产力和幸福感。.
It’s not the most comfortable experience, but…
Dilation is a crucial component of your eye exam. Dilating drops enlarge your pupils to allow more light to enter the eye, giving the doctor a better view of the interior and back of your eye. Think of it as looking through a keyhole – the larger and wider the keyhole, the more you can see into the room behind the door.
Why is dilation important?
If it’s so important, why isn’t it done in every eye exam?
Although it is recommended for everyone, dilation is not absolutely necessary for all patients and situations. Dilation can cause blurry near vision and light sensitivity for several hours after the drops are applied. To determine if dilation is needed and appropriate, your optometrist considers several factors:
Uveitis is inflammation inside your eye that usually occurs when your immune system fights an infection. It can also happen when your immune system attacks healthy tissue in your eye. Uveitis affects the middle layer of the eye, called the Uvea, resulting in white blood cells and proteins leaking. It can affect one eye or both eyes. Uveitis can affect anyone, but it is most common in people aged 20 to 60.
What are the symptoms of uveitis?
There are different types of uveitis.
What causes uveitis?
The cause of uveitis is not always known. Infections, systemic inflammatory diseases, or an eye injury can all cause uveitis. Smoking cigarettes can increase the risk of uveitis.
How is uveitis treated?
Your optometrist will most likely prescribe two eye drops: a steroid to reduce inflammation, and an eye drop to dilate the pupil to help with the pain and swelling. Uveitis can lead to permanent vision loss; therefore, early diagnosis and treatment are essential to prevent complications and preserve vision.
Macular degeneration is a condition that affects our macula – the spot on our retina responsible for crisp central vision and color vision. As we age, debris can build up in the macula and create deposits known as ‘drusen’. The drusen are the first signs that macular degeneration are present and can cause blurry vision and distortion to one’s vision.
Symptoms to look out for:
Who gets macular degeneration?
This condition is most common in patients over 60 years old. Some other risk factors are those with high blood pressure, family history, smokers, Caucasian patients, cardiovascular disease, and obesity.
How can I prevent macular degeneration?
Maintaining a healthy lifestyle, including diet and exercise is the best way to ensure your eyes stay healthy for as long as possible. The AREDS 2 study has shown that certain vitamins are beneficial in preventing the progression of macular degeneration, however, these vitamins have the best effect in patients who have already began to show signs of macular degeneration.
It is important for everyone to get their eyes examined yearly in order to be able to see as clearly as possible, as well as check for any signs of eye disease or conditions that can affect one’s overall health in addition to the eyes.
What is a cataract?
If we are lucky to live long enough, we will develop cataracts. A cataract is a clouding of the lens in our eye. Think about the process of cooking an egg, instead of being clear, the egg becomes white and cloudy.
Similarly, our lens becomes white and cloudy due to damage from the sun and UV rays. This is why it is important to wear sunglasses, hats, and UV protection when we are outside. These preventative measures can slow or delay the process of developing cataracts.
How will I know when it’s time to remove a cataract?
When vision is substantially affected, usually 20/40 or worse, or when it becomes difficult to drive at night due to glare from headlights, along with the appearance of the cataract itself, is when your optometrist will recommend surgical removal of the cataract.
Can cataracts be prevented?
Unfortunately, there is no way to predict who will get cataracts at what age, and how fast they will progress, but the best way to delay the development of cataracts is to wear sunglasses, and use UV protection when outdoors. Fortunately, cataract surgery is an elective surgery that is not urgent. Overall, cataracts are very common diagnoses and are not a big cause for concern.
眨眼是一种无需过多思考的非自主反射。虽然眨眼看似简单，但却非常重要。而且，信不信由你，眨眼也是有正确方法的。.
为什么眨眼如此重要？
20/20/20 法则
当我们长时间盯着屏幕或持续进行近距离用眼工作时，眨眼规律就会被打乱。验光师建议每个人都遵循“20/20/20”法则，尤其适用于屏幕使用时间过长的人。“20/20/20”法则指的是每隔20分钟休息一下，将视线移至20英尺（约6米）远的地方，持续20秒。.
有一个 正确的 眨眼的方式
我们希望每次眨眼都是完全的，也就是说，上眼睑应该完全贴合下眼睑。很多人眨眼时只眨到一半，或者睡觉时眼睛没有完全闭上，这种情况很常见。这会造成问题，因为这样会使下半只眼睛暴露在外，影响泪液的有效分泌。正如你可能已经猜到的，这会导致干眼症状。.
遵循 20/20/20 法则，并更加注意眨眼的方式，可以大大有助于减少我们眼睛在一天中的干涩感。.
