Why you're suffering from eye pain (and how to stop it)

A variety of conditions can cause eye pain, but if you catch it early, the discomfort can often be treated before it worsens. Here's what to look for.

Four main causes exist that can cause eye pain:

• Infections of the cornea such as keratitis can develop from the shingles virus (herpes zoster) or from a bacterial infection.
• Inflammation of conjunctiva, which causes conjunctivitis or pinkeye causes the white of the eye (sclera) to become red, itchy or painful and also have discharge.
• Abrasions on the eye or foreign bodies in the eye, such as scratches on the cornea, are extremely painful and usually require medical attention. Debris in your eye can usually be washed out with sterile water.
• Glaucoma in its early stages is not usually painful, but if pain occurs, you need emergency medical treatment. If left untreated, glaucoma can cause blindness.

It's extremely important that you care for your eyes throughout your life so you can preserve your sight for as long as you can. The Canadian Ophthalmological Association recommends that different age groups have their eyes checked at varying intervals:

• 19- to 40-year-olds should have their eyes examined a minimum of every 10 years.
• 41- to 55-year-olds need an eye check at least every 5 years.
• Over 56-year-olds must have their eyes scrutinized in 3-year cycles
• Over 65-year-olds should visit the ophthalmologist every second year.

If you experience pain in one or both of your eyes, you need to consult with your eye doctor as soon as possible. The doctor will be able to diagnose the condition and put you onto treatment straight away.

Eye safety also means taking care of your eyes when you complete tasks around your home, work in your garage and garden and when you're playing sport.

• Wear protective goggles or face-protective sports gear.
• Wash your hands thoroughly if you've worked with chemicals or cleaners.
• Handle spray cans sensibly.
• Show your children how to hold sharp objects like scissors and knives.
• Take frequent breaks when driving long distances or working on computers to reduce eye strain.
• Ensure that reading and work areas in your home and office are well lit but not over-bright.

Sight is a precious gift, and pain in the eye is uncomfortable and worrisome. Regular eye care is important to keep your eyes healthy and bright.
