What is high myopia?

myopia, also known as myopia, is an eye condition in which people have difficulty visiting objects that are far away, but clearly see objects that are in close proximity. People with high myopia have a high degree of nearsightedness and need objects to be very close to see them clearly. Myopia is usually corrected by glasses, contact lenses or surgery. This means that the light rays cannot bend at the eye, called a refractive error. Myopic eye cannot concentrate enough to clearly see distant objects. Lack of vision is measured in diopts, with positive numbers indicating foresight or difficulty to see close and negative numbers indicating myopia. Higher numbers, whether positive or negative, indicate a greater degree of deficiency. People with high myopia have recipes above -6.0 or -8.0 diopters. Regulations can go up to -35.0, which would indicate a very high degree of nearsightedness. Sometimes it degenerates, oris still getting worse with age and it often happens after a person grows.

High myopia is particularly likely to degenerate or result in damage to the eye, which may lead to loss of vision in rare cases. This may happen because the extension of the eyeball emphasizes the retina, causing it to separate or damage. High myopia can also be associated with cataracts and glaucoma. People with high nearsightedness should have regular eye tests and inform an eye care expert of any changes in their vision or eyes.

There are several different treatments for high myopia. Usually the treatment of the electorate lens. Goggles for high regulations must be very specific and carefully designed to accurately suit the eyes of the individual. The lenses for glasses must also be relatively strong, although the advances in the production of lenses significantly reduced. Contact lenses for high premiumSY reduces visual errors that can cause glasses of the same regulation, such as that everything looks less than it really is.

Surgery is also an option for people with this eye. The most common is laser -assisted eye surgery in situ keratomileusis (lasik), in which the laser cuts the flap in the cornea and removes some corneal tissue, allowing the light to bend properly when it enters the eye. Another option is the corneal rings in which the plastic rings are implanted in the eye to change its shape. Plastic rings can be removed or changed if the person's regulation changes if necessary. As with any operation, these procedures hold certain risks and are not suitable for allpatients.
