Cataracts occur when the crystalline lens, a translucide body behind the cornea, becomes opaque and prevents the light to enter the eye and reach the fungus. It is a normal process of ageing. It is one of the main causes of cecity in North America. Here is a list of different symptoms that you can feel:

• Your vision is blurry and foggy
• Your eyes are more sensitive to bright light
• You have the feeling that you are looking through a frosted glass
• Colours do not seem as bright
• You need more light when you look at close things

It's an affection that causes a red and irritated eye. The conjunctiva, the membrane that walls the interior of the eyelids and the white part of the eye, is affected. Allergies, bacterias or virus can be the cause of conjunctivitis.

Precautions :

• Avoid touching your eyes, it can be contagious
• Wash your hands before and after each application of the treatment prescribed by your doctor or optometrist
• Avoid wearing contact lenses

A high pressure inside the eye normally causes glaucoma. It is due to a misdrainage or an overproduction of the liquid inside the eye. It can lead to a loss of vision and even irreversible blindness. This pathology can appear at any age, but it is more frequent after the age of 40. It can also be hereditary. Glaucoma attacks the optic nerve. The optic nerve is a type of cable that links the eye to the brain and it is sensitive to an increase of pressure of the eyeball. People who suffer from glaucoma do not necessarily have eye aches, but they can notice the following effects:

• Blurry vision
• Red eye
• Ocular aches around the eye
• Halos around lights
• Photophobia
• Mid-dilated pupil
• Vomitting

If you suffer from diabetes, if an eye was injured during an accident or if you take cortisone, you must be more careful. You can prevent and control glaucoma, but you can not cure it. It is very important to have you internal eyes pressure checked regularly by your optometrist.

This pathology is associated with age and it gradually destroys the macula region on the retina. The macula is the central region of the retina responsible of the clarity of details and colours. In certain cases the pathology progresses very slowly and will have little effect on the vision. Women are more at risk than men are and smoking increases the risk of macular degeneration. The main symptom is blurry vision. Your optometrist can detect this pathology with an instrument called ophtalmoscope. A professional consultation is always the best solution.
