Treatment:
Removing the clouded lens and replacing it with a clear artificial lens

Treatment 
For adults, myopia can be reversed with refractive surgery, also called laser eye surgery. A laser is used to reshape the corneal eye tissue and correct the refractive error. Laser eye surgery is not recommended for children.

A tendency to hold reading material farther away to make the letters clearer

Blurred vision at normal reading distance

Eyestrain or headaches after reading or doing close-up work

Treatment 

Caused by: abnormal visual experience early in life that changes the nerve pathways between a thin layer of tissue (retina) at the back of the eye and the brain. The weaker eye receives fewer visual signals. Eventually, the eyes' ability to work together decreases, and the brain suppresses or ignores input from the weaker eye.

Signs and symptoms: 
1. An eye that wanders inward or outward

2. Eyes that appear to not work together

3. Poor depth perception

4. Squinting or shutting an eye

5. Head tilting

6. Abnormal results of vision screening tests

Treatment: 
1. Corrective eyewear. Glasses or contact lenses can correct problems such as nearsightedness, farsightedness or astigmatism that result in lazy eye.

2. Eye patches. To stimulate the weaker eye, your child wears an eye patch over the eye with better vision for two to six or more hours a day. In rare cases, wearing an eye patch too long can cause amblyopia to develop in the patched eye. However it's usually reversible.

3. Bangerter filter. This special filter is placed on the eyeglass lens of the stronger eye. The filter blurs the stronger eye and, like an eye patch, works to stimulate the weaker eye.
4. Eyedrops. An eyedrop of a medication called atropine (Isopto Atropine) can temporarily blur vision in the stronger eye. Usually prescribed for use on weekends or daily, use of the drops encourages your child to use the weaker eye, and offers an alternative to a patch. Side effects include sensitivity to light and eye irritation.

5. Surgery. Your child might need surgery if he or she has droopy eyelids or cataracts that cause deprivation amblyopia. If your child's eyes continue to cross or wander apart with the appropriate glasses, your doctor might recommend surgical repair to straighten the eyes, in addition to other lazy eye treatments.

2.Double vision.

3. Eyes that do not aim in the same direction.

4. Uncoordinated eye movements (eyes do not move together)

5.Loss of vision or depth perception.

Treatment 
Treatment for strabismus may include eyeglasses, prisms, vision therapy, or eye muscle surgery. If detected and treated early, strabismus can often be corrected with excellent results. People with strabismus have several treatment options to improve eye alignment and coordination.

Treatment 

In wet AMD, abnormal blood vessel growth in the eye leads to the leaking of blood and proteins into the macula, leading to subsequent vision loss. The wet form commonly results in advance visual loss within a short period of time.

Signs and symptoms 
- Blurring of central vision (may be gradual or rapid in onset)

- Shadows or missing areas of vision

Distorted vision e.g. a grid of straight lines appears wavy and parts of the grid appear blank

Problems discerning colours, specifically dark colours from other dark colours and light colours from other light colours

Slow recovery of visual function after exposure to bright light

Loss of contrast sensitivity (ability to tell diff erent levels of brightness apart)

Treatment
- Laser photocoagulation, surgical procedure involving the application of a hot laser.

- Photodynamic therapy with verteporfin. This method uses a non-thermal laser together with an intravenous drug to seal and halt or slow the progression of the condition.

- Drugs. Macugen and Lucentis are examples of drugs delivered into the eye through injections to block the growth of the abnormal blood vessels.

There are no active treatments for dry AMD, nut magnifiers could help.

- swollen or red eyelids

- when eyelids turn in; or when eyelids turn outward

- being in smoke, wind or a very dry climate

- looking at a computer screen for a long time, reading and other activities that reduce blinking

- using contact lenses for a long time

- having refractive eye surgery, such as LASIK

- taking certain medicines, such as:

    -diuretics (water pills) for high blood pressure

    -beta-blockers, for heart problems or high blood pressure

    -allergy and cold medicines (antihistamines)

    -sleeping pills

    -anxiety and antidepressant medicines

    -heartburn medicines

signs and symptoms 
- stinging and burning of the eyes

- blurred vision, especially when reading

- scratchy or gritty feeling like something is in your eye.

- strings of mucus in or around your eyes.

- eyes are red or irritated

- painful to wear contact lenses.

- have lots of tears in your eyes.

treatment 
- use prescription eye drops or ointments

- do warm compresses on the eyes

- massage your eyelids

- use certain eyelid cleaners

The feeling that there's something in your eye.

Your eye feels sensitive to bright light.

Crust along the eyelid.

A scratchy or itchy feeling around the eye.

Your eye makes extra tears.

Treatment 
- warm compress on The Eye 
- antibiotic eye cream or eye drops 
- draining of pus using needle (only done by professional) 

To maintain normal pressures, the inflow must balance the outflow. In certain types of glaucoma, eg angle closure glaucoma, if the drainage is blocked, fluid accumulates and pressure in the eye builds up. This raised pressure may damage the optic nerve.
