Hi, I am teacher & am working with a 10 year old who has difficulty in focusing his mind. For a child of his age this is quite unusual. His mother says: Because his eyes are very tired. And myopic degree is very high. The left eye 275, right eye 450. Astigmatism is especially serious. So, I am wondering if there is anything that Polyvision might be able to test to help with in relation to eye condition & behavioural response when focusing on learning. We are working online. However mum also says: His attention is always not very good. If you think you may be able to help, could you please explain a little & I will recommend to the mother that she bring the child for assessment. Thank you.

A Comprehensive Eye Examination (aged 3 or above) takes around 45 minutes . Covering:

  • Case History
  • Vision & Refractive Status
  • Binocular Vision
  • Color Vision Screening
  • Intra-ocular Pressure
  • Ocular Health
  • Fundus Photograph
  • Diagnosis & Recommendation

By appointment only

May suggest Binocular Vision Assessment / Visual Perceptual Assessment / Vision Training if needed.

本人雙眼做了白內障手術，右眼術後一切正常，但左眼眼角術後不停出現閃光，感覺眼球不停跳動，注目看電腦時特別嚴重，令人很不安及煩燥。術後檢查一切正常，視力、眼底、眼壓都正常，為什麼會有這種情況？手術至今已十七天，很令人擔心！

手術時有機會觸碰或牽動視網膜，換過人工晶體後也有可能改變視網膜所受拉扯力，引致閃光。如果醫生在術後檢查過沒問題，理論上情況會慢慢改善， 建議再觀察1個月。

如果有錐形角膜要點處理

如閣下視力不斷下降，普通有框眼鏡不足以提升視力的話，便需要配戴特製透氣硬鏡(隱形眼鏡)。部份錐形角膜個案可以針對性的手術治療或改善，但若情況嚴重，便可能要角膜移植。

如有懷疑，建議接受「全面眼科視光檢查」，由眼科視光師作出診斷及建議。

爸爸(77歲)喜歡拎住6.9”的手機睇YouTube片，距離眼睛大約30cm，如果改用較大螢幕的裝置(例如10.2”iPad)，使用距離依然是30cm，請問會對眼睛較好還是更傷眼？謝謝解答！

假設令尊在ipad上是使用全螢幕看youtube，眼睛比使用手機時需要移動更多以觀覽整個螢幕，理論上會使眼睛更疲勞，若想以ipad觀看又想有如使用手機觀看時相若的解像度，應放在約45cm觀看。
