While spectacles are a fashion statement for some people, for others they are an uncomfortable necessity. Though contact lenses may be a little more aesthetically pleasing they too can be quite uncomfortable and cannot be worn throughout the day. Thankfully, there is a third way to correct vision. Laser sugery or LASIK, it is a popular refractive procedure that can correct common vision problems, such as nearsightedness, farsightedness and astigmatism. This procedure aims at reshaping the cornea so that light entering the eyes can be focused onto the retina for the person to have a clearer vision.
- Laser surgery is pain-free and quick in most cases. Usually, it does not take more than 15 minutes to correct vision in both eyes. The results of this surgery can be seen in as little as 24 hours.
- The first step of laser surgery to correct vision is to create a thin, circular flap in the cornea. This is then folded back to access the stroma or underlying cornea. An excimer laser is then used to remove some of the corneal tissue.
- For people suffering from nearsightedness, the cornea is flattened while for people suffering from farsightedness, the cornea is made steeper. In cases of astigmatism, an irregular cornea is smoothened.
- Once the correct gradient has been achieved the corneal flap is put back into place and the cornea is allowed to heal naturally. There are no stitches or bandages required in a laser eye surgery.
- You may feel a temporary burning or itching sensation in your eyes immediately after the procedure. It is important not to rub your eyes or place any pressure on them. Your vision may also be cloudy or blurred for the first few hours.
- A doctor will usually advise you to rest for a few days after the surgery so that your cornea can heal properly. In a few days, your eyesight should stabilize, though, in a few rare cases, it may take a little longer. You should also avoid any form of strenuous exercising for a few days after the surgery.
Though LASIK surgery has a very high success rate, there are very rare occasions where spectacles may still be needed even after the surgery. Thus LASIK is a choice of treatment for many who seek freedom from glasses. In case you have a concern or query you can always consult an expert & get answers to your questions!
With everything requiring a computer to execute, more and more people end up looking at the computer screen for hours on end. This could range anywhere from a couple of hours to really long hours like 16 to 18. The effect of is a group of symptoms, which are collectively known as computer vision syndrome or CVS (syndrome means a collection of symptoms). The cause of this is the strain and pain resulting from constant staring at the monitor.
It is a type of repetitive stress injury, where a particular organ, the eye here, is subjected to repeated action (staring at a monitor) resulting in a group of symptoms. This is also compounded by age, where the flexibility to adjust to near and far vision is gradually reduced.
Symptoms of CVS:
There is no damage per se, but a constant strain on the eyes leads to:
- Blurred vision
- Double vision
- Dryness of the eyes
- Redness of the eyes
- Irritation of the eyes
- Headaches and neck/back aches
This could be a progressive condition, where the symptoms get worse with time. Treatment is definitely an option once the problem sets in, but this is a condition which can be definitely prevented with some simple, effective steps.
- Desk arrangement: Make sure the desk or monitor is slightly below eye level, about 30 inches away from the face. If you are straining the neck or the back to look at the monitor, it requires a change. The chair also can be changed in height to suit the seating. Also, prints can be pinned to the workstation when something is being typed, so constantly looking up and down while typing is avoided.
- Screen type: Move away from the older tube-style monitor with an LCD screen, which is easier on the eye. Check the computer settings so that brightness, contrast, and font size and shape and contrast are altered to suit your convenience. Ensure you are not requiring to strain to read.
- Alter the lighting: Look around you, and ensure there is adequate lighting with no glares on the monitor from surrounding windows or bright lights. A glare filter on the monitor is an effective way to manage this.
- Rest your eyes: Follow the 20-20-20 rule, with a 20-second break every 20 minutes where you look at something 20 feet away.
- Keep them moist: Blink your eyes constantly to ensure there is enough moisture. Eye drops can be used if required additionally.
- Frequent breaks: Not just your eyes, this also reduces strain on the neck and the back.
- Regular eye checkups: An annual visit, especially after 40, is a must for optimal eye health.
