I am 27 year old male and I have vision issue in my right eye since I was 18 yr old. I have done initial check up with an eye specialist and he suggested me that there won't be any issue in future as my left eye works perfectly. Kindly suggest what should I do?
My friend is 17 years old and has a power of -6 in both eyes. He is wearing specs from last 10 years, he started with -2. How can he control this growth with some Yoga/Exercise.
I had conjunctivitis in one eye a 3-4 days ago along with mild tonsils. Today when I woke up, the conjunctivitis had spread to the other eye as well with heavy pain in my throat. Upon looking in the mirror, I realised that the uvula is heavily swollen and in fact, just exhaling normally in pushing the uvula out. This is extremely painful. I am guessing that the first conjunctivitis will end soon and the uvula might become less swollen. So how long goes it take for the uvula to return to normal after conjunctivitis ends?
An important organ of the body, eyes must never be taken for granted and need to be protected at all times. In addition to protecting them, you also need to improve as well as maintain their overall health.
Here are some of the ways of keeping your vision in top form:
1. Eat for good eye vision
To have healthy eyes and consequently good vision, you need to have foods that keep them in good health. Nutrients like Zinc, Vitamins C and E and Omega-3 fatty acids can help to fend off age-related sight problems such as cataracts or macular degeneration (a condition characterized by the deterioration of the middle portion of the retina). Foods like eggs, nuts, green leafy vegetables, oranges and citrus fruits are what you need to have to get good eye health.
2. Kick the smoke habit
Smoking can adversely affect your eye health and can make you prone to eye conditions like cataracts, macular degeneration and damage of optic nerve (a nerve that transmits impulses from the eyes to the brain). By kicking this habit, you end up saving your eyes from irreversible damage.
3. Use sunglasses
Exposure to the sun’s ultraviolet rays for a long period of time can make you prone to common eye problems including cataracts. To protect them from the sun’s harmful rays, you need to use sunglasses that block 99-100% of ultraviolet A (UVA) and ultraviolet B (UVB) rays.
4. Go for a regular eye checkup
Going for regular eye examinations can help in protecting your vision and ensure you see clearly. Eye examinations are important to help you find eye problems like glaucoma (a condition wherein the optic nerve is damaged, resulting in vision loss). A comprehensive eye examination can help in identifying problems like nearsightedness, farsightedness or astigmatism (an eye defect that occurs to a deviated spherical curvature).
A common headache can have a number of reasons behind it, such as defective vision, hetrophoria or convergence deficiency, etc. Now, the question arises as to how they can cause headache. Read on to know more...
Q. Why should defective vision cause headache?
To attain a perfect vision, eyes with defective vision have to make sustained extra efforts, which results in headache. Even if the refractive error is very small, it can be the cause of headache. More prolonged the working and smaller the print, higher the incidence of headache.
Q. Can this occur at all ages?
Yes, it can occur at all ages. However, with age, the resistance decreases and hence elderly people are more prone to get headache. More the use of computer, mobiles, TV or prolonged studies precipitates headache
Q What is Hetrophoria?
Normally, both eyes always remain parallel, but in some cases, eyes have slight tendency to develop minor squint, may be convergent or divergent. This is called Hetrophoria or Latent squint. Such patients have to take extra strain to keep the eyes straight
Q. What is convergence deficiency?
For reading, both eyes have to converge and if there is weakness of convergence, extra strain has to be put on the eyes, which cause headache.
Q. What is the ideal method of refraction in young patients, I,e below 40 years?
Ideal method is to dilate the pupil with Tropicasyl plus drops. This has the advantage that the doctor can see the retina and Optic Disc. This is important to exclude any involvement of brain as the cause of headache. It also relaxes accommodation and hence provides correct refraction. In cases of Hypermetropia, it is extremely essential to dilate the pupil.
Q. What is the role of Autorefractmeter (a computer) in refraction?
It is a very important instrument to provide correct refraction, but it cannot be totally relied upon. Some opticians rely on it and give wrong numbers.
Q. What is acceptance Test?
You have refracted the eyes with Autorefractmeter or Streak Retinoscope but exact power is what a patient accepts. This is very important.
Q. What is astigmatism?
There is a difference in refraction in different meridians and it is important that a cylinder number is prescribed in correct axis. This is a difficult task and needs lot of experience.
Q. Is it important to correct astigmatism?
To relieve headache and strain on the eyes, it is very important that exact cylinder is prescribed.
Q. What is the role of exact centring of Optical Lenses?
.You may give correct number, but if the centre of the Optical lenses and cornea do not coincide, satisfactory results are not obtained. To dispense correct lenses is a big art and the Optician must be qualified and well experienced.
Q. Does the quality of lens affect the visual comfort?
Yes, it is important that quality of lenses should be good, preferable fibre lenses which are Ant reflect coated. Crizal coating with capability to block the UV rays are very popular.
Conclusion: Refractive errors are important cause of headache and needs proper examination of the eyes, preferably after dilating the pupil. Astigmatic error even if too small may be the cause of headache. Spectacle dispensing is an art and a patient must select proper optician. Spectacles if advised for constant use must be used constantly to get full relief.
