Laser Blended Vision
Laser blended vision is a laser eye treatment which is used to treat presbyopia (ageing eyes; progressive loss of the ability to focus on nearby objects) or other age-related eye conditions.Eye health: Presbyopia and your eyes. It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal spectacle correction due to ageing changes in the eye. It can be used for people who are also short-sighted (myopia) or long-sighted (hyperopia) and who also may have Astigmatism (eye), astigmatism. Primarily the treatment is for a condition called presbyopia. Laser Blended Vision can be achieved through laser eye surgery, usually performed as LASIK, although surface laser eye surgery Photorefractive keratectomy, PRK or LASEK can be used to produce the effect. Laser Blended Vision works by increasing the depth of field of each eye through subtle changes in the optics of the corneal spherical aberration. The increase in depth of field ...

Presbyopia
Presbyopia is physiological insufficiency of accommodation associated with the aging of the eye that results in progressively worsening ability to focus clearly on close objects. Also known as age-related farsightedness (or age-related long sight in the UK), it affects many adults over the age of 40. A common sign of presbyopia is difficulty reading small print which results in having to hold reading material farther away. Other symptoms associated can be headaches and eyestrain. Different people will have different degrees of problems. Other types of refractive errors may exist at the same time as presbyopia. This condition is similar to hypermetropia or far-sightedness which starts in childhood and exhibits similar symptoms of blur in the vision for close objects. Presbyopia is a typical part of the aging process. It occurs due to age related changes in the lens (decreased elasticity and increased hardness) and ciliary muscle (decreased strength and ability to move the len ...
