由於可能性太多，发炎可能与细菌感染或油脂分泌过剩有关，需多注意日常眼部清洁及护理。建议找眼科视光师或眼科医生作详细眼睛检查，查明真正原因。

深远视除配戴眼镜外，亦可选择配戴隐形眼镜。至於适合配戴与否需详细检查小朋友的眼睛实际状况及评估小朋友的生活习惯，自理及自律程度，可否妥善地安全使用及处理隐形眼镜。因此，建议阁下先带小朋友找眼科视光师作详细眼睛检查，再听取眼科视光师的建议再判断。

The jelly-like substance filling the space between the crystalline lens and the retina is called “vitreous humour”. The vitreous humour degenerates and liquefies when we get older, at which time we start to see floaters. Floaters can be moving opacities of various shapes and sizes (dots, circles, lines or spider webs). Physiological floaters usually occur when we are looking at a bright homogenous background such as a white wall or the blue sky. The floating opacities are few in number and remain unchanged over time. They represent normal physiological changes of the vitreous humour. As we age, the vitreous humour undergoes the processes of synchysis (liquefying) and syneresis (dehydrating and shrinking). These are normal agerelated degenerations.

Pathological floaters appear suddenly and may occur in great numbers. They may suggest bleeding within the vitreous humour, inflammation of the uvea or separation of the posterior vitreous humour from the retina. If the floaters are accompanied by flashes or visual field defects, it may indicate retinal tear or retinal detachment. When the vitreous humour contracts and detaches from the retina, it is called acute posterior vitreous detachment (acute PVD), at which time sudden onset of floaters and flashes occur. Floaters can be caused by vitreous opacities or haemorrhages, whereas flashes are caused by the vitreous humour pulling on the retina. An urgent dilated eye examination is essential to check for retinal tears, which should be repaired with laser as soon as possible, to prevent it from evolving into retinal detachment within a few hours.

怀疑是痣或色素变化，建议接受「全面眼科视光检查」，由眼科视光师作出诊断及建议。

色弱问题暂时未有方法可处理，而本中心亦暂时没有提供予色弱患者的协助工具。

如果阁下发现的黑影会跟随眼睛转动而移动的，有机会是飞蚊症的徵状，建议阁下作全面眼睛检查以排除视网膜疾病的可能性。一般而言，出现飞蚊是眼睛随年龄增长而退化的正常徵状，但若飞蚊在短时间内突然出现大量或增加，或见到闪光，则担心有视网膜病变或脱落的徵状，建议尽快找眼科视光师或眼科医生作全面眼睛检查及跟进。

恕未能单凭描述判断阁下的眼睛的实际情况，其实有很多原因导致眼乾，例如睡眠时间不足丶眼睛过度疲劳及眼睛泪水分泌不足等，而眼睛随年纪退化亦是可能性之一。建议接受「全面眼科视光检查」，由眼科视光师作出诊断及建议。

正常情况下验度数不需要先作放瞳，但眼科视光师会因应情况决定是否需要放瞳再作检查。透过散瞳剂能放松睫状肌以更准确检查屈光度数。可是，度数准确性可因不同原因而有所差异，故未能在此为阁下作判断。建议阁下接受「全面眼科视光检查」，当中包括放瞳眼底检查，详细检查眼睛内外健康状况後，包括有否白内障或青光眼，再由眼科视光师作出判断及跟进。

大部份的散光是先天性，度数变化不大。另如眼皮过紧丶经常摔眼有机会令散光加深。

如果只是偶尔进行此动作时（如动作很快地站立）才见到阁下提及的发光现象，有可能是血压突然改变所致。如果情况变得频密或明显，有可能会是视网膜出现问题。如有怀疑，建议接受「全面眼科视光检查」，由眼科视光师作出诊断及建议。
