Can you imagine a life without eyes? Many things will be difficult! Because they’re essential, it’s best to get to know them and the conditions and treatments that help improve your eyesight.
You Can Buy Different Contact Lenses
When you want a clearer vision without the glasses, your next best option is contact lenses for sale. The question is, which will you choose?
Contact lenses may look similar, but they have different styles and purposes. For example, some of them can last longer such as every month or fortnightly. Others are ideal for one day only. If you have difficulty seeing in different directions, the multifocal lens may be what you need.
Note, though, that not everyone can wear contact lenses. They may be not ideal for people prone to eye infections. They are not the best choice for those who have less patience in maintaining lenses.
The Brain Can Process Images FAST
By now, you know the eyes can see images fast. What many are not aware of is the speed.
A 2014 study showed that the brain could process images within 13 milliseconds! It’s way faster than 100 milliseconds revealed by other research. That’s not the only surprising part. The other is how the brain and the eyes process these images.
The retina is the thin eye tissue that converts the images into neural signals the brain can interpret. These signals then travel through the optic nerves. The “pictures,” though, arrive in the brain upside down. The brain is a remarkable organ it can adjust this image and correct it using different tools such as perception.
The Blind Do Dream, Although Differently
One of the biggest mysteries of life is whether the blind dream. The answer is yes, they do. How it happens may differ from those with eyesight. A 2014 study published in Sleep Medicine revealed fascinating details about dreaming while blind:
- The blind’s ability to perceive visuals when dreaming depends on when they lost their eyesight. Those with congenital blindness don’t see images at all. But they can smell and hear.
- People with late-onset blindness can dream with images or motion. But the longer they are blind, the lesser they perceive these pictures.
People of all shapes and sizes can have dreams, but they are a variety of ways on how they happen.
A Person Will Experience Poor Vision Loss at Some Point
As a person ages, the body parts also deteriorate. These include the eyes. Presbyopia refers to the progressive vision impairment that occurs during the middle to late ages. It happens because the crystalline lenses, responsible for focusing light, lose their elasticity. They can become stiff, so they can no longer adjust.
It is incurable but manageable. Your doctor can recommend many steps and treatments. Your options include reading glasses, progressive lenses, multifocal contact lenses, and even surgery.
Aren’t your eyes amazing? They can experience problems, but as long as you manage them as soon as possible, these organs will continue to serve you well.
