This is a very common issue after cataract surgery. Or, at least some people consider it an issue while others are not bothered at all by it.
The additional glow or light in the eyes that is often visible in the eyes of someone who had cataract surgery is a result of reflections of light from the acrylic material in the intra-ocular lens that is used. Many people are startled by the increased "shine" coming from their eyes, even in low light situations. Some have even likened it to animal eyes that glow in the dark.
Remember though that this increased reflection of light in the eye after cataract surgery is merely a function of the lens that was inserted and is purely cosmetic. It does not affect the vision of the person who had the surgery, but even so, some find themselves self-conscious about this change.
Many surgeons will not tell you that there is actually a choice in lenses that can be used and some will be less prone to this. If this is a concern of yours, make sure you ask your doctor ahead of time about your options in the type of lens that is used.
If you have already had cataract surgery and wish to fix this issue, the only option is to undergo another surgery to exchange lenses.
