How to correct myopia?

Myopia is shortsightedness and in this case the power of eye is increased from normal eye power. 

For example: The normal power of eye is 58DS. The eye power >58DS will be considered as myopic eye. e.g. the eye with Power of +60DS is a myopic eye. And the myopia of this eye will be -2DS (60-58). 

The myopia can be corrected through glasses, contact lenses and refractive surgery. The minus lens is placed inform of the eye equal to the myopic power of eye to neutralize the myopia of eye in glasses of contact lens form. The minus or concave lens is the option to treat or manage myopia.

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti

Causes of Astigmatism

Astigmatism is a common refractive error that occurs when the cornea (the clear front part of the eye) is shaped more like a football than a basketball. This irregular shape causes light entering the eye to be focused unevenly on the retina, resulting in blurred or distorted vision at all distances. There are several potential causes of astigmatism, including genetics, underlying health conditions, and environmental factors. Genetics Astigmatism is often inherited and is usually present from birth. It is caused by an inherited irregularity in the shape of the cornea or lens. If one or both of your parents have astigmatism, you are more likely to develop the condition. Underlying Health Conditions Certain health conditions can cause or contribute to the development of astigmatism. These may include: Keratoconus: This is a rare condition in which the cornea becomes thin and bulges outward in an irregular shape, causing astigmatism. It is often the result of gene
