It’s important for adults to have eye exams on a regular basis to check for problems.
Regular eye exams are critical for detecting:
• Age-related macular degeneration (AMD)
• Diabetic retinopathy
But everyone needs regular eye exams.This is particularly important if you have risk factors or a family history of eye problems.
Eye checks are recommended for:
• Children at 6 months old
• 3 years old and at 5 or 6 years old.
• Children are also recommended to get checked every year after until 18
• Adults should see an eye doctor at least every two years and annually after age 60.
What happens during an eye check?
You’ll likely have all or most of the following eye tests (you may also have more specialized eye tests):
• Eye muscle movement test: To test muscle strength and control
• Cover test: This is a check for how well your eyes work together.
• External exam and pupillary reactions: The doctor will watch the reactions of your pupils to light and objects at close distance.
• Visual acuity test: You’ll sit in front of an eye chart, with letters that get smaller as you read down each line. You cover each eye in turn and, using the other eye, read aloud, going down the chart, until you can’t read the letters anymore.
• Retinoscopy: By checking the way light reflects from your eyes, the doctor gets an approximate idea of the lens prescription you need now.
A cataract is a clouding of the lens inside the eye, which leads to a decrease in vision. It is the most common cause of blindness, found mostly in the elderly, and is conventionally treated with surgery.
Those with cataracts commonly experience difficulty:
• differentiatingcolors and changes in contrast
• recognizing faces
• and experience problems coping with glare from bright lights.
Cataracts are especially important to get fixed as they can become a major safety hazard for drivers, workers, as well as decrease the quality of life for the surrounding family members.
For example, they have economic implications for families:
• reduced productivity of the visually impaired person
• opportunity costs to household members who look after them Recent publications suggest that the global annual loss of economic productivity due to visual impairmentis between $19,223 million and $22,764 million.
Treatment of Cataracts:
• Cataract removal can be performed at any stage
• Surgery is usually ‘outpatient’ and performed using local anesthesia.
• Approximately 90% of patients can achieve a corrected vision of 20/40 or better after surgery.
