Have you ever been to the ophthalmologist and while he checked your eye mentioned strange names that happened to be eye conditions that you were absolutely unfamiliar with? If that's you, and it somehow got you wondering about the seriousness of these eye problems then, you got to know more.
Not every eye condition can lead you to immediate blindness unless you ignore it. So, here's what we're going to do. We're going to educate you about the most commonly spoken of eye conditions - what they mean, share a few symptoms, remedies and that should be enough for you to get an understanding. So, next time, you won't just be nodding your head while the doctor speaks, you'll know enough to discuss your eye condition for better solutions.
Let's start with the most obvious 20/20 vision.
- Visual acuity:- 20/20, 15/10, 60/20,etc. The accuracy of one's vision is measured at a distance of 20 feet. A person with 20/20 vision can see quite clearly at that distance of what a normal vision must be able to see. 20/20 is really not perfect vision but, instead, it indicates sharpness of vision. To be more precise, an individual with 20/20 vision can see alphabets 1/10th the size of what an individual with 20/200 vision can see.
- Vision screening:- an effective way to identify if you need glasses. It involves a method to screen the vision of the individual detecting anything amiss with the eye or a possible bad eye condition. The vision screening chart is preferred among children above 3 and individuals. Apart from, eye power, even conditions such as cataracts, glaucoma, astigmatism, eye misalignment can be discovered.
- It is said:-
- • Persons between ages 20 - 39, should get their eyes checked thrice at least
- • After 40 - every 2 years
- • After 65 years - every year
- Refractive error:- this refers to the shape of the eye that keeps one from focusing well.the length of the eyeball or the shape of the cornea plays an important role in determining healthy vision.
- Types of refractive errors include:-
- • Myopia: nearsightedness - close vision is better than distance vision
- • Astigmatism: failure to focus because light is bent differently on the retina
- • Presbyopia: close vision is bad and unable to focus
- • Hyperopia: farsightedness - can see distance better than close objects
- Glaucoma:- usually known as the silent killer of eyesight, it settles on the vision without prominent symptoms. Blurry vision, halos, headaches, eye pain. Built up pressure to the eye damages the optic nerve and this pressure has to be brought down before you lose your sight. Treatment would involve - the traditional surgery or eye drops, pills and Laser trabeculoplasty, etc.
- Twitching eyelids:- excessive blinking, involuntary movements, light sensitivity and tired eyes are some symptoms. The involuntary movements of the eye muscles is similar to minor muscle spasms that happen in one or both eyes. If it happens to be a chronic condition, one can consider facial injections or removal of muscles surgically.
This is just the basics but believe us when we say there's more.
