Contact Lenses In Pakistan

In the past, contact lenses in Pakistan were most common in young people aged 20-25, but today the average age of new contact lenses in Pakistan wearers is 38 years. The development is most likely due to the fact that today it is possible to correct for both distance and reading vision with contact lenses in Pakistan. Nowadays, contact lenses in Pakistan of all age groups are used.

Why Wear Contact Lenses In Pakistan?

At higher degrees of nearsightedness and farsightedness, the visual impression is optically better with contact lenses in Pakistan than with glasses. The use of contact lenses in Pakistan also creates fewer inconveniences in connection with sports and in the rain, and similar cosmetic considerations are also a contributing factor to many people preferring to wear contact lenses in Pakistan rather than glasses.

Contact Lenses In Pakistan Types

Contact lenses in Pakistan can be divided into soft and hard contact lenses in Pakistan. There are many different types of both soft and hard contact lenses in Pakistan, each of which caters to different vision and comfort needs.

Soft contact lenses in Pakistan

Takes partial shape after the eye and rests on the conjunctiva.

They make up 92 percent. of all contact lenses in Pakistan sold in Pakistan.

Shaped Contact Lenses In Pakistan

Are rigid contact lenses in Pakistan that rest either solely on the cornea (small lenses) or on both the cornea and the conjunctiva (large contact lenses in Pakistan) without taking shape. They make up 8 percent. of all contact lenses in Pakistan sold in Pakistan.

The soft contact lenses in Pakistan rests on the conjunctiva. The dimensional lens rests on the cornea

What Are Contact Lenses In Pakistan Made Of?

Contact lenses in Pakistan are available in several different materials. shows an overview of the different types of contact lenses Pakistan used in Pakistan, divided into materials.

Soft contact lenses in Pakistan(hydrogel lenses) are made of gel-like aqueous plastics called hydrogels. Soft contact lenses in Pakistan are very thin and flexible and partially adapt to the surface of the eye. The contact lenses in Pakistan cover the entire cornea and rest on the conjunctiva.

Since the introduction of soft contact lenses in Pakistan in the early 1970s, they have been popular. The popularity is due to the fact that they are typically immediately comfortable and easy to use, and that the risk of dropping them out of the eye is minimal. 92 pct. of all contact lenses in Pakistan sold in Pakistan are soft contact lenses.

Silicone hydrogel contact lenses in Pakistan are an advanced type of soft contact lenses in Pakistan. They are more porous than regular hydrogel contact lenses in Pakistan, allowing even more oxygen to reach the cornea. Silicone hydrogel contact lenses in Pakistan were introduced in 2002. Today, they are among the most popular contact lenses in Pakistan used in Pakistan .32 pct. of all lenses sold in Pakistan are of this type.

Oxygen To Pass

Shaped contact lenses in Pakistan are rigid – but porous – contact lenses in Pakistan that allow oxygen to pass through them. It makes them more comfortable to wear on the eye than conventional hard contact lenses, PMMA contact lenses in Pakistan(see below). Shaped contact lenses in Pakistan often provide sharper vision than soft and silicone hydrogel contact lenses in Pakistan do. This is especially true for major vision defects. It takes time to get used to form-fitting contact lenses in Pakistan, but after the initial adjustment period, most people find form-fitting contact lenses in Pakistan just as.

Comfortable as hydrogel contact lenses in Pakistan. Shaped contact lenses in Pakistan cover either only the central part of the cornea (Figure 1B) or both the cornea and the conjunctiva (Figure 1A). 8 pct. of all contact lenses in Pakistan sold in Pakistan are form-fitting contact lenses in Pakistan.

Hybrid Contact Lenses In Pakistan

Hybrid contact lenses in Pakistan are, as the name suggests, a mix of hard and soft contact lenses in Pakistan. They consist of a solid, rigid oxygen-permeable central zone surrounded by a peripheral zone of hydrogel or silicone hydrogel material.

The purpose of this construction is to achieve a wearing comfort on a par with the soft contact lenses in Pakistan and at the same time ensure the sharp vision that can be achieved with dimensional contact lenses in Pakistan. 0.5 pct. of all contact lenses in Pakistan sold in Pakistan are hybrid contact lenses in Pakistan.

PMMA (polymethylmethacrylate) 

PMMA contact lenses in Pakistan are made of a transparent, rigid plastic material called polymethylmethacrylate (PMMA). A PMMA lens has really good optics, but no oxygen can penetrate the contact lenses in Pakistan, making it difficult to use due to longer habituation. PMMA contact lenses in Pakistan are only rarely used today. Just 0.1 pct. of all lenses sold in Pakistan are PMMA contact lenses in Pakistan.

Carrying Time And Replacement

Depending on how the contact lenses in Pakistan is surface treated, proteins and fats will be deposited from the tear film to a greater or lesser degree.

Despite careful care, all contact lenses in Pakistan need to be replaced after a shorter or longer period of time.

Soft contact lenses in Pakistan can usually be worn all day long. Are these one-day contact lenses in Pakistan, they are discarded when the day is over. In the case of multi-day contact lenses in Pakistan (weekly or monthly contact lenses in Pakistan), they must be cleaned and disinfected before being put on the eye again the next day.

24-Hour Contact Lenses In Pakistan

24-hour contact lenses in Pakistan can be worn around the clock. That is, they are used both day and night. They are typically replaced after one to two weeks and at the latest after one month. In general, 24-hour contact lenses in Pakistan should only be used for special needs. However, soft day contact lenses in Pakistan can sit well in the eye for a single night without significantly increasing the risk of complications.

24-hour contact lenses in Pakistan can be worn around the clock. That is, they are used both day and night. They are typically replaced after one to two weeks and at the latest after one month. In general, 24-hour contact lenses in Pakistan should only be used for special needs. However, a soft day lens can sit well in the eye for a single night without significantly increasing the risk of complications.

Special contact lenses in Pakistan, for example with very high intensity, will usually be replaced every 3.-12. month.

Hard Contact Lenses In Pakistan

Hard contact lenses in Pakistan are worn throughout the day or for the number of hours per day that the eye is trained to tolerate. Selected types of hard contact lenses in Pakistan can also be used as 24-hour contact lenses in Pakistan.

Contact Lenses In Pakistan Design

A contact lens in Pakistan can be designed in many different ways. The design depends on what the contact lenses in Pakistan are correct for.

Contact Lenses In Pakistan Spectrum 2018

Spherical contact lenses in Pakistan are correct for either myopia or farsightedness. They have the same power over the entire optical part of the lens.

Toric Contact Lenses In Pakistan

Toric contact lenses in Pakistan correct for structural defects along with either myopia or farsightedness. They have different strengths in different directions (for example, vertical and horizontal).

Multifocal (multi-strength)Contact Lenses In Pakistan

Multifocal (multi-strength) contact lenses in Pakistan correct for myopia (old-age farsightedness, presbyopia) along with nearsightedness or farsightedness, possibly with structural defects. They have several strengths. The distance to the object you are looking at is decisive for what strength you are looking at.

Cosmetic contact lenses in Pakistan have a colored iris painted and can be used with or without correction for optical defects.

In case of construction defects, the light rays gather in different places in the eye depending on the direction.

For Example,

The vertical rays (red) can accumulate in front of the retina and the horizontal rays (yellow) on the retina (A). With negative contact lenses in Pakistan that refract light in only one direction (here the vertical one), the vertical rays can be moved back on the retina, so that the focal point hits the retina’s yellow spot (macula), where you see clearly.

In presbyopia, the rays from distant objects on the retina are collected, while the rays from close objects can no longer be focused on the retina because the eye’s own contact lenses in Pakistan have become rigid. A multi-power lens (bottom) can collect the rays from different distances on the retina so that it is possible to see clearly at long distances (A: blue zone and blue rays) and short distances (B: red zone and red rays) using only one lens. In monovision, contact lenses in Pakistan on one eye are used to correct distance vision, and another contact lenses in Pakistan on the other eye to correct reading vision. The principle is the same as using an old-fashioned monocle.

Adjustment Of Contact Lenses In Pakistan

Only licensed optometrists and ophthalmologists may adjust contact lenses in Pakistan. To be able to make the lens correctly, one must take into account the information mentioned in Figure 10.

Overview of the parameters (conditions), contact lenses in Pakistan as a minimum is made according to. The values ​​in the table only serve as an example.

Spherical

Spherical indicates how many diopters the nearsighted (-) or farsighted (+) should be corrected for.

cylinder

The cylinder indicates the magnitude of the building defect (astigmatism) in diopters. The cylinder is indicated only in the case of toric contact lenses in Pakistan. Minor structural defects do not need to be corrected, as the tear film behind the contact lenses in Pakistan ‘smooths’ them out.

Axis

Axis indicates the orientation of the cylinder in degrees.

Addition Indicates

Addition indicates in diopters how much is to be added to the spherical value in order to be able to see clearly in the reading distance when using multi-power contact lenses in Pakistan. If this is not possible, you can use ordinary reading glasses with contact lenses in Pakistan.

For Toric Contact Lenses In Pakistan

For toric contact lenses in Pakistan, the direction of the cylinder must be indicated. Using various devices on the contact lenses in Pakistan, it is possible to prevent them from rotating on the eye.

The diameter of the lens is given in millimeters from edge to edge. The diameter is important as it determines where on the eye the edge of the contact lenses in Pakistan rests. Incorrect diameter can cause irritation or poor / unstable vision function.

Rear Curvature Of The Contact Lenses In Pakistan

The rear curvature of the contact lenses in Pakistan is given in millimeters. It should preferably have a greater curvature than the anterior curvature of the cornea.

Contact lens diameter (A) Rear curvature of the contact lens (B)

Special Contact Lenses In Pakistan

After eye injuries and especially corneal diseases, special contact lenses in Pakistan may be needed. These contact lenses in Pakistan must be manufactured individually by an optician who has experience with this.

Dry Eyes

Dry eyes can be a reaction to the use of contact lenses. In some cases, large, form-fitting contact lenses in Pakistan (scleral contact lenses in Pakistan) can relieve the severe pain caused by very dry eyes.

Night Contact Lenses In Pakistan

Night contact lenses in Pakistan (ortho-k lenses) are designed to flatten the cornea and thus correct for myopia. Ortho-k contact lenses in Pakistan are worn at night. During sleep, they change the shape of the eye in such a way that contact lenses in Pakistan wearer can be spectacle-free and contact-free during the day. With few exceptions, it is necessary to use ortho-k lenses every night to maintain the effect.

Night contact lenses in Pakistan work best for myopia up to about -6.00. Specially designed night contact lenses in Pakistan may help reduce the development of myopia in children and adolescents.

Quality And Prices Of Contact Lenses In Pakistan

A contact lens in Pakistan subscription for ordinary soft contact lenses in Pakistan costs Pakistan between 100 and 500 kroner a month. The varying prices reflect differences in contact lenses in Pakistan type, contact lenses in Pakistan quality, and subscription terms.

The type of lens depends on the needs of the contact lenses in Pakistan wearer within single-power, construction-fault, or multi-power contact lenses in Pakistan.

Lens Quality

The lens quality can be difficult for the individual contact lenses in Pakistan wearer to assess. But with special one-day contact lenses in Pakistan is

– as opposed to spectacle contact lenses in Pakistan – it is possible to try it out in collaboration with an authorized professional. Based on your own experience, you can choose the quality that meets your needs.

Subscription terms cover control terms, replacement of contact lenses in Pakistan, replacement lenses in case of loss, and the like.

Security

Contact lenses in Pakistan are a foreign body that is inserted into the eye. It can feel unnatural as the eye is very sensitive. The contact lenses in Pakistan can also cause damage to the eye. If this happens, the eye will become irritated with redness and tearing. If the eye is irritated, remove the lens.

If the symptoms do not disappear the next day, the contact lens wearer should seek help from an optician or ophthalmologist. For increasing pain, the lens wearer should seek help as soon as possible, as the pain may be a sign of corneal inflammation (see the Eye Association’s brochure ‘Red Eye’).

Red-eye

Red-eye is one of the most common symptoms that something is wrong with the eye or that the eye is responding to a disease somewhere in the body. The eye …

The vast majority of eye infections that occur in connection with the use of contact lenses in Pakistan can be treated effectively with early intervention. In Pakistan, it is estimated that there are approximately 400,000 contact lenses in Pakistan users. Of these, approximately 20 eyes each year have a permanently significantly reduced vision due to contact lens use. Thus, the risk of serious injury is fortunately small.

Reduce The Risk Of Infection

To reduce the risk of infection, contact lenses in Pakistan should not be worn in swimming pools. In addition, it is recommended to have good hand hygiene when handling contact lenses in Pakistan.

A not uncommon reason for contact lenses in Pakistan to give up – even after many years of use – is that the eye reacts to the contact lenses in Pakistan or cleansers.

The use of day or night contact lenses in Pakistan increases the risk of eye infections, so these types of contact lenses in Pakistan should only be used in special cases. Only a professional can give advice on this.

The cornea is usually clear and translucent, partly because it does not contain blood vessels. Poor oxygen permeability in the contact lenses in Pakistan or corneal inflammation can cause blood vessels to begin to grow into the cornea. If the blood vessels grow into the central optical zone, it will cause visual impairment. Ingrowth of blood vessels may therefore mean that the use of contact lenses in Pakistan must be discouraged.

Children And Contact Lenses In Pakistan

Children can wear contact lenses in Pakistan. However, except in special cases, children should only start using contact lenses in Pakistan when they are able to handle the contact lenses in Pakistan themselves without the help of their parents.
