What Patients Say
- Wilmer Stevenson, Creative manager

When asked what makes optometry so rewarding, he said "My job is rewarding because sometimes even the simplest treatment can change the patient's confidence in himself/herself and I feel that I am part of a larger global healthcare promotion program."

Common Optometry questions
What is 6 / 6 or 20 / 20 visual acuity ? Does this mean perfect vision?

Visual acuity generally means the clarity and the sharpness of vision. It measures the ability of the eye to distinguish the smallest details of objects. Visual acuity measured by the eye chart (usually Snellen) on the distance of 6 meters, which is equivalent to 20 feet. The term 6/6 or 20/20 and the other fractions (such as 6/18 or 20/50, etc.) is used to express the amount of visual acuity at a standard distance (6m or 20ft) compared to a person with normal vision. Example: If your visual acuity is 6/36, it means you must be as close as 6 meters from the object to see what a person with normal visual acuity can see at a distance of 36 meters. 6/6 does not mean perfect vision in all cases; it is only an indication of the extent of sharpness and clarity of vision.

Vision measurement: is the measurement of visual acuity and the ability of the eye to distinguish the smallest details clearly, whether with or without glasses.

Glasses measurement: it measures the degree of refractive errors in the eye, whether they are nearsightedness, farsightedness or astigmatism.

It is known that wearing glasses improves the quality of vision and thus the vision is worse without them, but this does not mean that the vision becomes worse than before, or that the person is adapted to glasses. The truth is that the brain is adapted to clear vision. Worsen vision has nothing to do with wearing glasses or not. If a person’s vision has the ability to decrease for any reason, his or her vision will decrease even if he or she wears glasses because glasses do not correct the vision or worsen it.

One of the natural changes that occur in the eye with age is presbyopia, which often appears after the age of 40, where the vision of nearby objects is relatively blurred and becomes clear when they are further away from the eye. With age, the flexibility of the lens of the eye (that enables us to see close and far objects by changing its convexity according to the distance of the object we want to see) gradually decreases. Presbyopia can be corrected by reading glasses or special contact lenses.

One of the most common misconceptions about contact lenses is that they can get lost behind the eye. Anatomically, nothing can be entered behind the eye due to the presence of the conjunctiva which is a thin transparent lining that covers the white part of the eye (sclera) and extends and twists to line the inner surface of the upper and lower eyelids, making contact lens loss behind the eye impossible, but the lens may become stuck inside the eyelid when it is not fitted correctly on the cornea.

In general, if the prescription of the glasses is ± 4 diopters or less, then the prescription of the lenses is often the same as the glasses, but if the prescription is greater than ± 4 diopters, then there are mathematical methods to glasses prescription to contact lenses. The contact lenses have more details that must be taken into consideration, such as the astigmatism, the diameter and base curve of the lens, and so on, so it is preferable to consult an optometrist.

One of the most important prohibitions when wearing contact lenses is the use of water to clean or moisten the lenses, or swimming and showering while wearing them! Where it can cause the transmission of some dangerous microorganisms from the water, including the parasite (Acanthamoeba), which leads to serious complication to the cornea, which may lead to vision loss. Contact lenses should be cleaned only with the solution, not water or lubricant drops. If you feel dry eye while wearing the lenses, you can use preservative-free lubricant drops.

No, hard contact lenses do not treat or stop the progression of keratoconus, they only correct the vision with better quality and clarity than glasses or soft contact lenses.

No, glasses make vision clearer and reduce eye strain, but they do not correct or improve vision after taking them off. As for children, glasses are very important in treating amblyopia (lazy eye), and in some cases, they are a non-surgical treatment for strabismus (eye squint).

Amblyopia (lazy eye) refers to a decrease in visual acuity in one or both eyes during the critical period for the development of the visual system, which is approximately before the age of seven. It is caused when the brain receives a blurred image from the eye, either due to uncorrected refractive errors, squint, or any eye diseases (such as congenital cataract), which impair the stimulation of the nerve pathways between the eye and the brain properly, and thus the brain ignores the weak eye that weakens its ability to see. It can be treated by treating its cause and stimulating the lazy eye to work. When the diagnosis or treatment is delayed, the child may have lifelong vision problems that are not corrected by anything, and the treatment will be less effective in adults than in children, and they may end up with permanent vision impairment. Here, we stress the importance of routine eye examination in children.

No, there are types of drops that are in the form of single-use, but they are not lubricant eye drops, such as some drops for inflammation or pain relievers, which must be taken with a prescription for certain cases and for a short duration only, and the continued use leads to serious complications in the cornea. As for the lubricant drops, they are safe for all the day use and do not require a prescription.
