As we cross a certain age, not only do we begin to experience a gradual decrease in overall strength and energy but also a steady decline of visual acuity. While some of the vision related problems such as Presbyopia cannot be considered as a serious disease, there are others such as glaucoma, macular degeneration and diabetic retinopathy which certainly qualify as serious eye diseases. Most of these problems occur with age.
Presbyopia usually occurs in people who are over 40 years when they find it relatively hard to focus on objects that are up close. The reason behind it is the hardening of the natural lens. It is a progressive problem and requires reading glasses or laser surgery to correct the problem.
Cataract is another such problem that mostly occurs in people over 60 years of age. The only possible way to get rid of this problem is surgery. In case, your cataract has reached an advanced stage, then the doctors may suggest implantation of multifocal lenses to restore normal vision.
However, as mentioned earlier, these diseases are not very serious and can be easily treated.
When it comes to some major eye related problems, macular degeneration is one that should be taken very seriously as it happens to be one of the leading causes of blindness across the globe. Glaucoma and Diabetic Retinopathy are also two serious eye diseases which affect the quality of life of millions of ageing population.
So how exactly does ageing affect our vision?
Ageing causes certain subtle changes in the structure of our eyes which, in turn, affect the quality of our vision. A gradual reduction in pupil size, for instance, can cause vision impairment. This happens due to degeneration of muscles that control pupil, thereby affecting its response to light. This is one of the reasons why older people tend to easily dazzle by bright light.
Dry eye is another common age-related problem which occurs due to a decrease in production of tears. It can cause a lot of discomforts and burning sensation. Age also adversely affects the peripheral vision, which decreases at the rate of around 3 degrees after every 10 years. This is why older people are always at higher risk of accidents on the road.
You may also find it hard to differentiate between colours after a certain age. The sensitivity of cells that help perceive colours reduces with time, which also reduces the ability to perceive colours.
Floater is also a common problem among elderly people. It occurs when the transparent vitreous humour inside the eye begins to develop some imperfections, forming clumps of tissue. These clumps cast shadows on the retina, thereby forming web or spot-like structures in the field of vision. However, sometimes it can also be an indicator of retinal detachment.
