Better vision = Better quality of life

Better vision means more quality of life, but the basis for better vision is a precise professional eyesight test at an
eye care specialist in order to provide you with the right individual eyeglass lenses. The following ZEISS online vision screening check can help you quickly and easily determine whether it's time to have such a professional eyesight test.

Three effective vision screening checks

The online vision screening check is divided into three parts:

  • Visual Acuity Check
  • Contrast Vision Check
  • Color Vision Check

Gewinnspiel

Wir verlängern unser Gewinnspiel! Bis zum 30.09.2012 haben Sie nun noch die Chance, einen von 100 Preisen im Anschluss an den Online-Seh-Check zu gewinnen.


Tolle Preise warten auf Sie:
1. - 10. Preis je 250 €
11. - 100. Preis je ein ZEISS Brillen-Reinigungsset

Since the color and screen settings of monitors are all calibrated somewhat differently, some preparation needs to be done to precisely display the vision screening check and thus to obtain a precise result. Please read the following 4 steps and follow the guidelines. As soon you are done, we calculate the correct display settings for the vision screening check automatically.

If you already wear a vision aid (eyeglasses or contact lenses), you should wear them during the vision screening check. If you have more than one vision aid, please wear the vision aid you normally use when working on a computer.

1. Monitor screen calibration

Adjust the distance between the two lines by clicking the +/- button. The distance between them must be exactly 5.4 cm. To make the measurement you can use the short side of a credit card or debit card or a ruler.

5,4 cm
+
-

2. Color calibration

Adjust the brightness of the striped frame to the central box by moving the slider.

3. Distance to display

Please place yourself at a distance of 70 - 100 cm from the display. You will get exact advice with every single check.

Your contrast sensitivity seems to be deficient; you could possibly see better with ZEISS precision eyeglass lenses using i.Scription® technology that are customized to your visual needs. The image demonstrates how your contrast vision – especially at night might be improved.

Your contrast vision seems to be okay but you could possibly see better with ZEISS precision eyeglass lenses using i.Scription® technology that are customized to your visual needs. The image demonstrates how your contrast vision – especially at night might be improved.

You seem to have optimal contrast vision.

Your contrast vision seems to be deficient; you could possibly see better with ZEISS precision eyeglass lenses using antireflective technology that are customized to your visual needs. The image demonstrates how your contrast vision – especially if you are affected by glare at night - might be improved.

Use your keyboard or the mouse to select the arrow to indicate the direction of the open side of the “C”. Your individual result for this check will be displayed automatically as soon as we have evaluated your color vision level.

You probably have a color vision problem. Please visit an eye care professional for further help.

Unfortunately, color vision problems cannot be corrected with eyeglasses or contact lenses. However, there are many tips that can help you master your day to day activities despite a color vision problem.

You probably do not have any color vision problem and can perceive your surroundings in full color

參加蔡司網上視力檢查。

在此處進行測試,以確定你是否需要進行一次眼睛檢查。

眼睛是我們最重要的感知器官。這就是優良視力如此重要的原因。然而,許多人並不進行定期眼睛檢查,以確保最佳視力。蔡司100年來提供的優良視力─100年來提供的高質素精準眼鏡鏡片和眼鏡光學的創新科技。

利用蔡司網上視力檢查[1],以進行簡單快捷的視力測試。測試結束後,將建議知是否需要諮詢蔡司視光師或眼科醫生以獲得專業意見。

網上檢查你的視力

優良視力也意味著更高的生活質素,因為視覺是我們最重要的感知器官。我們從周遭環境所得到的印象大約有80%是經過眼睛。讓眼睛護理專業人員為我們進行定期眼睛檢查是預防性健康護理的一部分。一般而言,如果我們沒有已知的眼睛問題,應該每兩年進行一次眼睛檢查。蔡司網上視力檢查能讓你初步了解你目前的視力表現[1]。

你多久會進行一次眼睛檢查?

成人(沒有或沒有已知的眼睛疾病) 應該定時進行眼睛檢查

  • 20 至39 歲期間最少進行三次
  • 40 歲以上每兩至三年進行一次
  • 40 歲以上每一至兩年進行一次

兒童應由專業眼科視光師進行定時眼睛檢查

初次檢查﹕於 2 歲至最遲 3 歲半

第二次檢查﹕入學之前

然後每兩年進行一次- 即使沒有明顯眼睛問題 - 以確保能及早發現隱性眼睛問題及視力問題並進行及早護理。

所有早產嬰孩以及所有存在斜視或嚴重視力缺陷家族病史的兒童,應該盡早進行眼睛檢查 - 於出生後 6 至12 個月 - 然後定期檢查。

篩選檢查包含那些測試?

該網上視力篩選檢查分為三個部分:

  1. 視力檢查
  2. 對比視力檢查
  3. 色覺檢查

視力檢查

這是一項非常重要的檢查。大多數眼鏡配戴者都對這個檢查相當熟悉。視光師要求您閱讀字母或數字,並辨識特殊環形(Landolt環)的開口方向——在螢幕上每個大小不同。視光師檢查您是否可以輕輕鬆地辨識各個環形的大小。然後,視光師會進行一個被稱為主觀驗光的程序。將不同度數的鏡片置入測試鏡架後,視光師會詢問你戴上各個鏡片後的視覺變得更好或更差。視光師會先為一隻眼睛進行主觀驗光,然後再為另一隻眼睛驗光。接著會進行雙眼測試,以檢查眼睛的協調能力。其他的測試也可用來識別所謂的相關性隱性斜視症狀,而這種隱性斜視往往可被改正,並且可在某些情況下接受治療。

首先,在我們的免費網上檢查中,我們會在螢幕上測試您的視力表現。這不能取代視光師進行的測試。但是,您可獲得您視力的初步資料。

眼睛檢查需要確定矯正在沒有調節力(眼睛自動適應各種距離)的情況下的視力缺陷所需的屈光度數。

0.00 D (度)

正常視力 (正視眼睛)

0.00D 以外的度數
(度)

缺陷視力 (非正視眼睛)

例如: 遠視 +2.00 D (度)

遠視 - 老花 (隨年齡增長而逐漸喪失近距離對焦能力)

例如: 近視 -1.00 D (度)

近視 - 六百度近視以上被定義為高近視

散光 -1.00 D (度)

散光 - 眼睛會把一點看成為拉長的一條線

對比視力檢查

一開始時,您可能會認為這個檢測不是那麼重要。但是,對比視力對於舒適視覺來說意義重大。如果我們不能區分對比度的差異,可能會造成眼睛疲勞。我們都知道當電腦螢幕的對比度設定不正確時,或當我們在燈光暗淡的情況下閱讀時,會產生一定的不適感覺。

對比視力檢查對於辨識我們視覺系統所發生的轉變來說非常重要。例如,對比敏感度的變化可能是青光眼的徵兆。

我們網上測試中的第二部分是對比視力測試。此檢測可能會令你首次知道你的對比視力並沒預期中的好。您的視光師將很樂意深入檢查更多細節。

色覺檢查

我們所知的“色盲”所影響的男性多於女性。這是一種遺傳缺陷,在全球影響多達1.8億人。為此,我們有多種類型的鏡片可供使用。

  1. 患此症狀者只能有限地分辨某些顏色。感光細胞——紅色、綠色和藍色視錐細胞——均存在於視網膜中,但是有部分無法正常運作。常見的症狀是紅/綠色盲。
  2. 部分色盲:在這種形式的疾病中,某些感光細胞完全不存在或無法運作。患者只有兩種感光細胞類型能正常運作。這導致色覺明顯減弱。尤其是對於紅色弱和紅色盲的司機而言,這有時候會很危險。例如在霧中,他們只能看到一片黑色,而不是前方汽車紅色尾燈。
  3. 完全色盲:這種稱為全色盲的病例十分少見。患有此症狀的人根本無法感知任何顏色的細微差別。

為了診斷這個症狀,眼睛保健專業人員使用三種不同的測試:偽同色圖、Farnsworth 測試和Nagel's色盲檢查鏡。

在我們免費網上檢查中的第三部分,您可以使用彩色圖表檢測您色覺。
