What is MYOPIA?
Myopia also called near-sightedness is a condition in which close objects appear clearly, but far ones don't. Near-sightedness tends to run in families.
It is the most common cause of impaired vision in people under age 40. In recent years, its prevalence is growing at an alarming rate.
If you are nearsighted, you will have difficulty reading road signs and seeing distant objects clearly, but will be able to see well for close-up tasks such as reading and computer use.

CAUSES
1. Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye. This causes light rays to focus at a point in front of the retina, rather than directly on the retina.
2. Hereditary

SIGNS AND SYMPTOMS
1. Squinting
2. Eye Strain
3. Headache
4. Feeling fatique when driving or playing sports.
5. Large eyeballs
6. Large cornea

If you experience these signs or symptoms while wearing your glasses or contact lenses, schedule an eye exam with your Optometrist to see if you need a stronger prescription.

DIAGNOSIS OF MYOPIA
Myopia can be easily diagnosed using standard eye exams given by an eye doctor.

MANAGEMENT
1. Concave or Minus Spectacle Lenses
2. Concave or Minus Contact Lenses
3. Refractive Surgery

OTHER HELPFUL TIPS
1. Depending on the degree of your myopia, you may need to wear your glasses or contact lenses all the time or only when you need very clear distance vision, like when driving, seeing a chalkboard or watching a movie.
2. Myopia typically begins in childhood, and you may have a higher risk if your parents are nearsighted. In most cases, nearsightedness stabilizes in early adulthood but sometimes it continues to progress with age.
3. . Also, consider photochromic lenses to protect your eyes from UV rays and high-energy blue light and to reduce the need for a separate pair of prescription sunglasses outdoors.
4. Some type of MYOPIA  can increase with increase in age, while others remain the same throughout an individual's lifetime. Therefore visit your eye doctor regularly to know the type you have.

6 WEIRD EYE ISSUES YOU SHOULD NEVER IGNORE!!!

TELL THE TRUTH: How often do you really pay attention to your eye health? 💖 Basically only when you realize you have to squint to see the TV, or you notice the sun affects your eyes or maybe you have difficulty reading tiny prints, right? Bear with me while I sound like your mom for a sec—your eye health is something that you should absolutely be paying special attention to (you like to see, don't you?). Take changes in your vision, for example–flashes of light, black floaters, blurriness, smoky vision, cloudy vision, dark spots. Noticing those changes and getting them checked out early can be life-saving—and not just for your vision. They could be early signs of conditions like, diabetes, hypertension, sickle cell,  HIV, strokes, or even cancer—and yeah, you want to catch that stuff early. 💖 Yes the  diseases mentioned above can be noticed in the eyes! That’s why we Optometrists recommend a comprehensive eye exam every one to two years, even if you don’t need to chang

HAEMOLACRIA (BLOODY TEARS)

Can you imagine crying tears of blood? It may sound like a horror movie, but bloody tears are actually a real thing. Blood in the tears is a rare condition known as HAEMOLACRIA 💖 💖  HAEMOLACRIA is a physical condition that causes a person to produce tears that are partially composed of blood. It can manifest as tears that are anything from merely red-tinged to appearing to be entirely made of blood. 💖 CAUSES OF HAEMOLACRIA 💖 1. CONJUNCTIVAL INJURY: The conjunctiva is a clear tissue membrane that lies on top of the sclera, the white part of the eye. Within the conjunctiva is a meshwork of blood vessels. Sometimes infection, inflammation or laceration can cause bleeding of the conjunctiva since it is so blood vessel-rich. The blood simply seeps out and mixes with the tears, making it appear as if the person is making tears with blood in them. 💖 2. BLOOD DISORDERS:  Blood disorders including hemophilia can cause excessive bleeding due to clotting problems. 💖 3
