Online Amsler Grid Test for Macular Degeneration and Other Macular Disorders

The Amsler Grid test is a simple screening test used to assess the area in the back of the eye that is responsible for your most detailed vision (used for reading, seeing facial details etc).  This area is called the Macula and it is located in the center part of the retina (the nerve lining inside the eye – used for sight).

If there are any diseases or degenerations (like Macular Degeneration) that are affecting the Macula – then the Amsler grid test will usually provide early detection that there may be a problem going on.

HOW TO USE THE AMSLER GRID:

Position yourself at about 14-16 inches (about 40 cm) away from the grid.

If you have glasses that you use to read with – make sure you are looking thru the reading part of your glasses

Cover the left eye and use only your right eye to see the grid.

Stare at the white dot in the center of the grid with your uncovered eye.  Keep your eye focused on the dot.  Don’t move your eyes around to see any other part of the grid except for the white dot.  Use your side vision (peripheral vision) to see all the other parts of the grid.  “Glue” your sight to that white dot – don’t move your eye around at all.

While staring at the white dot:

  • Can you see all 4 corners of the grid?
  • Can you see all 4 sides of the grid?
  • Are any of the lines WAVY or MISSING or DISTORTED?   (All lines should look perfectly straight, all intersections should form right angles and all the squares should be the same size.)
  • Are ther any holes or “missing areas” in  the grid?

Then cover the right eye and repeat the steps with using the left eye to see the grid.

If you answered “YES” to any of the above questions then you need to see your eye doctor immediately. The eye doctor will examine the back of your eye and your macula VERY closely to determine if there are any medical issues causing these changes on the Amsler Grid test.

If you have been told that you have macular degeneration or any other macular disorder, you should be doing the Amsler Grid test at home DAILY.

The Amsler Grid is a great way to monitor your macular health but you should always have yearly eye examinations with dilation when dictated by your doctor.

Video: Contact Lens Tips for Insertion, Removal and Cleaning

This is a good video from Optifree that gives instructions on Contact Lens insertion, removal, proper cleaning and other instructions and tips for successful contact lens wear.

ALWAYS wash, rinse and dry your hands thoroughly each time you handle your contact lenses. This will help eliminate germs (bacteria, viruses, fungus etc) that can cause eye infections and vision loss.

Clean, Rinse and Disinfect your contact lenses after wearing them. Make sure that you DO rub your contact lenses (even if the solution says “No Rub”) – this will help in loosening any deposits, films or debris on your lenses.   Saline solutions are used to RINSE contact lenses (NOT to clean or store contacts) – use multipurpose solutions for cleaning and storing contacts.

Remove your lenses IMMEDIATELY if they become uncomfortable or your eyes become red and/or light sensitive. Discomfort and irritation can be an early warning sign of a problem.  If discomfort continues AFTER you remove your contact lenses – IMMEDIATELY contact your eye doctor.

DO NOT INSERT A CONTACT LENS INTO AN EYE THAT IS RED, IRRITATED, PAINFUL  OR UNCOMFORTABLE!!

Do NOT sleep in your contact lenses. People who sleep in their contact lenses have a higher risk of eye infections and ulcerations.

DISCARD your contact lenses as directed by your eye doctor (daily, weekly, bi-weekly, monthly etc). Wearing a contact lens longer than the approved wear time can cause infections and corneal distortions (the front of the eye can become warped with contact lens overwear).

Do NOT swim, shower or bathe in your contacts.  Tap water and pools can have organisms in them that can cause infections an even PERMENANT vision loss.

Have YEARLY Contact Lens Eye Examinations. Your eye doctor can re-evaluate and re-fit (if needed) your contact lenses for you every 12 months.  Sometimes contact lenses feel comfortable even if they are causing problems.  Your eye doctor will evaluate if the prescription needs to be changed to get you the most precise vision and they will also evaluate if the contact lens that you are wearing is causing problems that you may be unaware of.
