Presbyopia- Introduction

Presbyopia is a condition in which the affected person can see objects at a distance very clearly, but cannot properly see the objects close to them. It is a condition where the eye exhibits a progressively diminished ability to focus on near objects with age. It is natural part of aging and almost everyone gets it, It is a result of loss of elasticity of the crystalline lens.

Presbyopia is generally believed to stem from a loss of flexibility and gradual thickening of the natural lens located inside the human eye.It is an age related process.

The age related changes appear within the proteins in the lens, thus making the lens less elastic and harder over a period of time.

Presbyopia happen inside the proteins in the lens, generating the lens tougher and a smaller amount elastic more than time. Age-related modifications also take location inside muscle fibers surrounding the lens. 

With fewer elasticity, the eye includes a tougher time focusing up near. Other, a lesser amount of well-liked theories exist too.

It is very different to Farsightedness and nearsightedness.

Difficulty seeing dim light, difficulty seeing objects at a previously comfortable distance, headaches, tiredness and stress due to discomfort with eye, are all symptoms of Presbyopia. The people affected by it, tend to need brighter light to see more clearly.

Visual acuity, Retina examination, Refraction test, muscle integrity test, slit lamp test are some of the examinations done to check for Presbyopia.

Glasses, Lens and certain types of surgeries can help in the treatment of Presbyopia. It is very common as people age and there is nothing to fear about. But people who tend to show the signs must visit the doctor as early as possible, to prevent any complications from happening.

Myopia- Introduction

Myopia or nearsightedness or shortsightedness, is a condition in which the light coming in, does not fall on the retina, which is at the back of the eye. As a result of this, the objects nearby appear clearly, while the objects in a distance appear out of sight or blurry.

 

It affects 20% to 30% of the population. It is not curable.But the eye disorder can be easily corrected with eyeglasses, contact lenses or surgery.

Since the people affected can see near objects but not objects a little further away, they do exhibit several unique signs and symptoms, using which other people can identify their problem.

Children do get affected by this and they might not be able to tell about their problem and parents can identify their problems using some basic signs and symptoms. They might report head aches often and can be seen squinting to see objects in a distance.

Myopics often tend to move closer to what they want to see and generally prefer to keep their books very closer to read.

There are many causes for Myopia. It can be hereditary, external environment can play a role. The structure of the eye and the amount of stress it goes through can also act as a reason for Myopia.

It is not completely curable as said before, but the problems can be corrected very easily. Glasses, lenses, exercises and surgeries can help in correcting Myopia to a certain extent.

There are several tests conducted by the eye specialist, like the Visual acuity test, Retinoscope and the use of phoropter. Using these tests the extent of Myopia's effect can be determined and treatment can be carried out based on the results.
