Know more common eyes disease 了解更多常見眼疾 

常見眼疾 : 

1. 乾眼症 : 當您的眼睛沒有產生足夠的眼淚以保持濕潤時，或者當您的眼淚無法正常工作時，就會發生乾眼症。他可以讓你的眼睛感到不舒服，而且在某些情況下，它也能引起視力問題。 乾眼症很常見——它每年影響數百萬美國人。

2. 白內障: 是在眼睛晶狀體中形成的密集、混濁的區域。當眼睛中的蛋白質形成團塊阻止晶狀體向視網膜發送清晰的圖像時，白內障就開始了。 它發展緩慢，最終會干擾您的視力。您可能最終會患上雙眼白內障，但它們通常不會同時形成。白內障在老年人中很常見。美國有超過一半的人在 80 歲時患有白內障或接受過白內障手術。

3. 青光眼 : 是由于视神经退化导致最终可能失去视力，大多数病例眼压升高。能够观察到的症状包括急性青光眼患者会感到眼痛，视力模糊，并可见光环。也可能伴有头痛，恶心，呕吐，因为眼压过高。许多患者没有任何症状，急性青光眼在亚洲人中较常见，且近年来年轻人（如30多岁）患病的比例在增加。

4. 飛蚊症 : 漂浮物是漂浮在您視野中的黑色小形狀。它們看起來像斑點、線、波浪線，甚至是小蜘蛛網。 大多數人都有來來往往的飛蚊症，他們通常不需要治療。但有時飛蚊症可能是更嚴重的眼部疾病的徵兆。

5. 黃斑病變 : 年齡相關性黃斑病變 (AMD) 是一種眼部疾病，可使您的中央視力模糊。當衰老對黃斑造成損害時就會發生這種情況——黃斑是控制銳利、正前方視力的眼睛部分。黃斑是視網膜（眼睛後部的光敏組織）的一部分。

AMD 是一種常見疾病——它是老年人視力喪失的主要原因。AMD 不會導致完全失明，但失去中央視力會使看臉、閱讀、開車或做特寫工作（例如做飯或修理房子周圍的東西）變得更加困難。

6. 視網膜脫落 : 視網膜脫離描述了一種緊急情況，其中眼睛後部的一層薄薄的組織（視網膜）從其正常位置拉開。

視網膜脫離將視網膜細胞與提供氧氣和營養的血管層分開。視網膜脫離未經治療的時間越長，受影響眼睛永久性視力喪失的風險就越大。

7. 糖尿病視網膜病變 : 是一種眼部疾病，可導致糖尿病患者視力下降和失明。它會影響視網膜（眼睛後部的光敏組織層）中的血管。 如果您患有糖尿病，重要的是每年至少進行一次全面的散瞳眼科檢查。 

8. 此外，不同年龄阶段的个体可能存在不同的眼病，如儿童的视力问题、斜视、弱视，或在学龄和工作年龄的群体中，如视力疲劳、干眼症或视力异常，以及40岁以上的人群则可能出现老视

Common Eye Conditions : 

1. Dry Eyes : Dry eyes occur when your eyes don't produce enough tears to stay moist, or when your tears don't work properly. It can make your eyes feel uncomfortable, and in some cases, it can cause vision problems. Dry eyes are common -- it affects millions of Americans each year.

2. Cataracts : are dense, cloudy areas that form in the lens of your eye. A cataract starts when proteins in the eye form clumps that prevent the lens from sending clear images to the retina. It develops slowly and eventually interferes with your vision. You may end up with cataracts in both eyes, but they don't usually form at the same time. Cataracts are common in older people.  More than half of Americans have cataracts or have had cataract surgery by the time they are 80 years old.

3. Glaucoma: It is caused by the degeneration of the optic nerve, which may eventually lead to loss of vision. In most cases, the intraocular pressure is increased. Symptoms that can be observed include eye pain, blurred vision, and visible halos in patients with acute glaucoma. It may also be accompanied by headaches, nausea, and vomiting because the intraocular pressure is too high. Many patients do not have any symptoms. Acute glaucoma is more common in Asians, and the proportion of young people (such as those in their 30s) suffering from the disease has been increasing in recent years.

4. Floaters : Floaters are small black shapes that float in your field of vision. They look like spots, lines, squiggles, or even tiny spider webs. Most people have floaters that come and go, and they usually don't need treatment. But sometimes floaters can be a sign of a more serious eye disease.

5. Macular degeneration : Age-related macular degeneration (AMD) is an eye disease that can blur your central vision.  This condition occurs when aging causes damage to the macula - the part of the eye that controls sharp, straight-ahead vision. The macula is part of the retina, the light-sensitive tissue at the back of the eye.

AMD is a common disease - it is the leading cause of vision loss in older people. AMD does not cause complete blindness, but loss of central vision can make it more difficult to see faces, read, drive a car, or do close-up tasks (such as cooking or fixing things around the house).

6. Retinal Detachment : Retinal detachment describes an emergency in which a thin layer of tissue at the back of the eye (the retina) pulls away from its normal position.

Retinal detachment separates the retinal cells from the layer of blood vessels that supply oxygen and nutrients.  The longer a retinal detachment goes untreated, the greater the risk of permanent vision loss in the affected eye.

7. Diabetic retinopathy : is an eye disease that can lead to vision loss and blindness in people with diabetes. It affects the blood vessels in the retina (the light-sensitive tissue layer at the back of the eye). If you have diabetes, it is important to have a comprehensive dilated eye exam at least once a year.

8. In addition, individuals of different ages may have different eye diseases, such as vision problems, strabismus, amblyopia in children, or visual fatigue, dry eyes or abnormal vision in school-age and working-age groups, and presbyopia in people over 40 years old.
