Have you ever seen your parents, grandparents, or other elderly relatives have to move their books or phones in and out to see the text more clearly? This may be a sign that they are starting to develop farsightedness. But did you know that this condition is not just for the elderly? So let's observe ourselves to see if we are starting to develop farsightedness.
Checklist of symptoms of farsightedness
- Can see distant objects clearly than near objects
- See double vision because of straining the eyes
- Eyes squint or turn because of straining the eyes
- Eyes are sensitive to light, cannot withstand light, or eyes sting when exposed to sunlight
- Difficulty seeing at night
- Headaches, eye pain, and eye fatigue after reading books or focusing on things that are close for a long time
What causes farsightedness?
Farsightedness is caused by the focal point of light striking the back of the retina. This is due to the cornea being too flat or the eyeball being too short. The refraction of light entering the eye therefore occurs less. This condition can occur from birth or occur with age, which is called presbyopia. Presbyopia is caused by the muscles around the eye starting to degenerate, causing the lens to harden and lose elasticity. It is therefore unable to change shape and focus in the near range. This is the origin of blurred vision in the near range.
How to correct farsightedness
If your vision is 200 (+20) or you are 50 centimeters away from an object and still cannot see clearly, then you need to correct your farsightedness. The easiest way to fix it is to get glasses or contact lenses.
The lens used for farsightedness correction usually uses a lens called a convex lens to compress the light to meet at the retina. However, sometimes, especially for the elderly, there may be complex vision problems that are not clear both near and far. Therefore, it is advisable to use progressive lenses, which will help you see clearly at all distances without having to take off your glasses or look through your glasses when looking close up. This will help you maintain your personality and reduce eye fatigue from straining your eyes.
Remember that the most important thing before getting glasses is to have your eyes examined by a specialist to choose the right lenses for yourself. And when you wear glasses, don't forget to come back for eye check-ups regularly to adjust your vision to the current level.
