Our eyes are the lenses through which one of our most important senses, vision, operates. Roughly about 80 percent of the things that we perceive are derived from this sense, sense of vision. If you maintain good ocular health, then you will reduce the chances of suffering from vision loss and will also significantly cut down on the odds of developing blindness. If you take proper care of your eyes, you will also keep away a lot of the diseases of the eyes such as glaucoma and also cataracts.
How The Eye Works
The way our eyes work is that when the light gets reflected off an object that we are looking at, we get to “see.” As it starts to enter our eyes, the light becomes unfocused. The main part of being able to wee is to make sure that the light is focused on the retinas of the eyes. This is the part of the eye that is light-sensitive and is found within the eyes. After this light gets focused, it starts the process of stimulating the cells in order to send a lot of information to the brain. The part of the brain that is at the back of the head interprets this information and this is what makes us able to see what we are looking at.
The importance of light retraction
The light that enters the eye is refracted by the cornea. This is the clear window that is placed on the outer surface of our eyeballs. The cornea is responsible for providing the eye with its optical prowess. Once the light passes through this cornea, it gets bent once again. This is done in order to adjust the focus more finely with the help of the crystalline lens that is found within the eyes. The lens is responsible for focusing light onto the retina.
A lot of the vision problems that we face occur due to an error in the process by which our eyes do the job of refracting light. In the case of nearsightedness, which is known as myopia, these rays of light are responsible for forming an image that is in front of the retina. In the case of farsightedness, which is also known as hypermetropia, the rays get focused behind our retinas.
Vision Exams: Adults
The current way of life in the 21st century makes more demands from our eyes than ever before. This is why it is highly recommended that all adults undertake at least one eye examination per year. This is not recommended just for the sake of detecting whether or not you have any problems with your eyes or not, but it is also very important in maintaining the health of your eyes, Take glaucoma, for example, is a disease that takes place if there is too much increase in pressure on the eyes. If not tested, this can go unnoticed and can in the long run cause us some serious problems. Other things that also go unnoticed are diseases like cataracts and also macular degeneration that is related to age. Another very good reason to get regular vision tests is to make sure that your eyes are functioning properly with regard to the demands of modern-day educational and professional demands.
Vision Exams: Young Adults and Children
Children who suffer from vision that has not been corrected face an incredible amount of challenges in life. They will face a lot of challenges in some of the most important aspects of life including their academic, social engagement, and also their ability to participate in athletic activities. If this demographic makes sure to get proper and good eye care, then they can very significantly overcome these challenges. This will make sure that these children can make the most out of the potential that they are born with.
Eye Exams Are Essential: Period
When you undergo an eye exam, the service that is offered by the doctor is not one that is restricted to just giving you a prescription for your eyeglasses or your contact lenses. They also make sure that you are facing any of the common eye problems that the age group you belong to normally gets afflicted with. The doctors will also make sure that your eyes work well together as part of a team and they will also factor in the role your eyes play in your overall health. In fact, you may be surprised to know this, but eye doctors are some of the first people who are able to detect the early onset of high blood pressure and also diabetes in patients. So, yeah, regular eye exams are kind of part and parcel of good eye care.
Preventative Maintenance: Red Light Therapy
The main theory that is able to explain the effects that red and near-infrared light has on us, does not matter which part of the body it is, involves the relationship between the mitochondria and light. The main function of the mitochondria is to make sure that energy is produced for the cells it is. The main way in which light therapy can help is by improving the ability they have to make this energy.
Light therapy is a type of therapy that has been getting more and more popular in recent days. In fact, some of the biggest celebrities on the planet are some of the people who have advocated the benefits this type of therapy is able to provide. The main way in which light therapy works is by stimulating the natural light of the outdoors in an indoor setting. The person who undergoes this particular type of therapy is required to sit in a lightbox that emits light that is as powerful as 10,000 lux units. This level of exposure to light has the potential to help us in multiple ways, one of them being that it prevents cell degeneration.
