What are the differences between pinguecula, pterygium and cataract?

Pinguecula and pterygium are growths on your eye’s conjunctiva, the clear covering over the white part of the eye. Pinguecula is a yellowish, raised growth on the conjunctiva. , while pterygium can remain small, or it may grow large enough to become uncomfortable or to interfere with vision. Both pinguecula and pterygium are believed to be caused by a combination of exposure to ultraviolet (UV) light from the sun, wind and dust. It will cause dry eyes and contact lens wearer will feel uncomfortable. Risk of pinguecula and pterygium can be reduced with wear sunglasses to protect your eyes from ultraviolet (UV) light, protect your eyes from dust by wearing glasses or goggles and use artificial tears when your eyes are dry.

A pterygium can be surgically removed if it is causing eye irritation or affecting vision. A cataract is a clouding of the lens in the eye which leads to a decrease in vision. Cataract usually caused by aging and this is normal. But there are also babies born with cataracts. Cataracts can also be caused by other eye conditions, past eye surgery or medical conditions such as diabetes. Long-term use of steroid medications, too, can cause cataracts to develop. Cataracts can only treat by cataract surgery, and there’s no eye drop or even supplement/food that can treat cataracts. Most cataracts develop slowly and don’t disturb your eyesight early on, but if impaired vision interferes with your usual activities, you might need cataract surgery. If cataracts are become thicken, they can cause other complications such as glaucoma that can lead to blindness. Symptoms of cataracts include blurred vision, fading of colors, sensitivity to light and glare.
