There are various signs that will indicate that
Sometimes labeled short-sightedness, it describes when objects that are near you are clear but the ones that are far are blurry. This might make it hard to see road signs and dangers from a distance. If you're sitting down at the back of a large conference room and you can't read the white board then consider getting an eye test. Sometimes individuals are not aware their vision isn't clear.
Also called 'long-sightedness', this is where objects which are far away appear clear but the ones that are near aren't. Other symptoms are trouble focusing and headaches. The mild cases don't need prescription lenses.
This is not a disease but a sign that you've got a different shaped cornea. Almost everyone has slight astigmatism. Unless this brings you constant headaches, you won't need corrective glasses.
The eye muscles can find it difficult to clearly concentrate on objects as you age. When you are holding the object out (like a magazine) just so it is possible to zoom in on the words then you definitely should get a scan. You must think twice about this when you hit your forties. These could be fixed by glasses or contact lenses.
Other conditions to look out for
If you feel like there's something in your eyes, or its watery, itchy or burning it could actually imply that it's dry. Never scratch your eyes. Try blinking more, increasing daily water consumption and get your eyes off the computer monitor every 45 minutes.
They're common as you grow older. If you notice an abrupt and immediate change, then go contact your optometrist.
That's where there is a raised tissue spot around the white area of your eyes. It's going to often be visible on both eyes. While it's not dangerous you must get sunglasses and lenses with UV protection. Do not get cheap ones because the lenses might not have UV protection and can cause headaches because of the poor lens quality.
It's a natural outcome of ageing for many. It affects how well you see by clouding the lens area. It gets worse with time and distorts vision. Colours may look yellowish and dark areas may appear as your eye moves. Go to the physician to be sure.
It's an eye disease that may result in blindness. Fibres at the back of the eye gradually die due to pressure build-up. Symptoms might not be visible until quite advanced.
Age-related mascular degeneration
This is actually the main reason for blindness due to ageing. Waste amasses at the back of the eye impacting vision. Another variety triggers new blood vessels to grow at the back of the eye. As you get older you ought to think about getting your eyes scanned.
Get an eye test if you encounter any of these warning signs. If you get headaches it can sometimes be attributed to the eyes. Also, it is a good idea to be proactive and get your eyesight checked every six months for safety measure.
