1. Ocular hypertension causes and treatment

People with ocular hypertension have higher intraocular pressure (elevated IOP) than normal levels. Ocular hypertension can only be detected by your ECP using instruments, since it has no outward signs and symptoms. In most cases, the patients themselves can not realize this ocular problem.

2. Eye issues of preschoolers

Preschool children can be fine-tuning the vision when they master the complex hand-eye coordination. They can ride bicycles in right direction they want to go while dealing with pedal and steer. For some old preschoolers, they also play more sophisticated sports. Though preschool children who have already developed their vision during infant and toddle years, they are vulnerable to vision problems if they don’t correct some bad habits.

3. Refractive errors and treatments

Some people may be diagnosed with refractive errors after an eye exam, which means the eyes can not refract or focus light properly. The eye’s ability to focus light is decisive for one’s vision sharpness. Refractive eyeglasses, contact lenses as well as refractive surgeries can be used to correct a refractive error.

4. Eye color determination and changes

A child’s eye color is always inherited from its parents, even if the influences from each parent may not even. Eye colors include black, gray, green or other combinations.

5. Factors associated with human vision

The body’s abnormal immune responses can damage brain and nerve cells, resulting in multiple sclerosis, muscle weakness as well as vision problems. In 2007, a study conducted by Johns Hopkins Hospital claimed that an eye test named optical coherence tomography (OCT) could be used to identify and monitor multiple sclerosis. OCT could be used to test health conditions of nerve cells and only cost one-tenth of the fees of performing magnetic resonance imaging (MRI).

6. Diabetic retinopathy signs and treatments

The American Academy of Ophthalmology has ever claimed that diabetic people are 25 times more likely to lose vision than normal individuals. However, there are less serious eye diseases that are also caused by diabetes, such as diabetic retinopathy and glaucoma. It is widely known that diabetic patients can not use and store sugar in a normal way, resulting in high blood sugar.

7. Contact lenses for teens

Many teens prefer contact lenses to eyeglasses primarily for appearance reasons. They think that they look much better with contact lenses and self-esteem can be established. Another very important reason is the convenience brought by contact lenses. Wearing contact lenses during sports can give teens clearer peripheral vision without worry about the breakage of eyeglasses. Of course, a contact lens may be dislodged or lost, but replacing a contact lens is much cheaper than replacing a pair of glasses. And children spending much more time playing outdoors than adult are vulnerable to harmful UV rays. It is very convenient if they choose contact lenses because they only need to carry a pair of sunglasses. Contacts lenses can also correct astigmatism.

8. Chronic glaucoma risks

In contrast to acute glaucoma, chronic glaucoma (or primary open-angle glaucoma) has no obvious symptoms during its development process. This form of glaucoma gradually reduces the patient’s peripheral vision and permanent damage has become a reality once you realize it. It sounds scary and chronic is actually called “the silent thief of sight”.

9. Advantages and disadvantages of orthokeratology contacts

Also called ortho-k, orthokeratology is a kind of method that corrects vision by wearing designed rigid gas permeable contact lenses to reshape and flatten the cornea while sleeping at night. So that people need not to worry about extra emergencies happened with contact lenses or eyeglasses during sports. Wearers who have nearsightedness or astigmatism will receive clear vision without contact lenses or eyeglasses after they wear ortho-k lenses at the night.

10. Contact lenses evaluation for kids

Compared with eyeglasses, contact lenses have a lot of advantages. They can provide better peripheral vision and improve your performance in sports. With contact lenses, you don’t need to worry about the bad aspect of eyeglasses that are prone to breakage. Many contact lenses, such as gas permeable (GP) lenses, offer better optics than eyeglasses.
