1. Potential risks of eye injuries

The Prevent Blindness America (PBA) has ever pointed out that over 850,000 Americans suffer from various eye injuries every year, during home and work activities or outdoor sports. These accidents always lead to a lifelong regret. It is reasonable because the injured person can see perfectly well before the accident but his or her vision may be partially or even profoundly lost. Driving and reading may become impossible, not to say potential ugly appearance.

2. Peripheral vision causes and treatments

People with healthy eyes have two parts of vision: central vision and peripheral vision, which are independent. If a person has difficulty in seeing dim light or navigating while walking, he or she probably has peripheral vision problems. People with good central vision may be unable to see properly around the edges.

3. Common issues of eyeglass frames

The size of eyeglass frames also has standard format, such as 48-19-140. The first number is the size of the lenses and the second number represents the bridge size. The third one indicates the temple length. Different wearers require individual frame measurements and fitting. With these standardized size measurements, manufactures can provide accurate eyeglass frames.

4. Prosthetic contact lenses for disfigured eye

As their name suggests, prosthetic contact lenses are created to decorate disfigured eyes. They either mask eye flaws by trauma and eye diseases or block excess light for abnormally functioning eyes. Prosthetic contacts can provide a healthy eye appearance using custom-painted colors. They have no special difference in materials and care methods with regular contact lenses.

5. Ocular migraine symptoms and causes

Also called ophthalmic or eye migraines, ocular migraines are common and usually painless. They may cause various visual problems such as visual disturbances and the appearance of a small, enlarging blind spot in your central vision.

6. Myopia treatments

Also named nearsightedness, myopia is so common today that it is estimated to affect one-third of the population in the world. In contrast to hyperopia which deprive people from close vision, people with myopia can see up-close objects but can not manage distance things such as highway signs.

7. Keratoconus treatments

Patients with keratoconus always have a cone-like cornea, which deflects light on its way to retina. In one or both eyes, keratoconus may cause vision distortion.

As a progressive eye disease, keratoconus develops slowly. Since the cornea is always thinning, nearsightedness and irregular astigmatism may develop at certain stages of keratoconus, bringing distorted and blurry vision. Other symptoms of keratoconus include glare, light sensitivity and changing prescription.

8. Common issues of prescription eyeglasses

Some people think that eyeglass wearing makes the wearer rely on them. In fact, eyeglass wearing causes no permanent visual change. Based on the misconception, those people are not willing to wear eyeglasses when they just feel good with the vision. But in sometimes, their actual vision is burry, thus bringing more risk when they are driving on the highway, especially at night.

9. Introduction of Retinitis pigmentosa

Retinitis pigmentosa (RP) is the slow and gradual retina degeneration. Unfortunately, it occurs most in young children, whose both eyes may have poor night vision. As the disease progresses, both central vision and peripheral vision will be narrowed and blindness occurs in final.

10. Must-knows about contact lenses

Contact lenses provide fashion expression and a complete vision field suitable for sports without apparent eyeglasses, and eliminate the need for irreversible refractive surgery. Among vision correction ways for myopia, hyperopia and astigmatism, contact lenses have gained a 20% share in US.
