Who will tell me what my eye curvature is?

Anonymous

Question: Who will tell me what my eye curvature is? I go to an ophthalmologist but I only know my dioptres. Will he be able to tell me this parameter or do I have to visit a contactologist?

Lentiamo.co.uk

Reply: It is not enough if your contactologist (ophthalmologist or optometrist) tells you what your curvature is. It is important they also perform a so-called application. We would recommend you read the Contact lens guide.

The importance of contact lens diameter

Anonymous

Question: I know my eye curvature and dioptres but I can see that there are various diameters and I don’t know how important a lens diameter is and if it can have any impact on the eye.

Lentiamo.co.uk

Reply: Judging by your question I suspect that you would like to choose new contact lenses based on the parameters of your current lenses. That’s not the right way to do it and it could lead to certain complications. If you would like to change your contact lenses, explain your reasons to your contactologist – he will help you to pick suitable ones to do the job. I also suggest you take a look at the Contact lens guide.

How to understand information from a contactologist’s card

Anonymous

Question: My contactologist wrote this information about dioptres in my “Contact lens wearer” card: L = 2,25, R = 2,25. On my contact lens blister it says –2,25. When I’m ordering online, should I put in 2,25 or –2,25?

Lentiamo.co.uk

Reply: When ordering contact lenses, put in the same information as the one that’s on the lens pack (i.e. minus). Contactologists prescribe lenses the way you mentioned, the equal sign means minus for them.

Contact lenses and gel nails

Anonymous

Question: I have a question. I bought gel nails three weeks ago and I would like to start wearing contact lenses. I was at an ophthalmologist who told me that I could have lenses but I will have to get rid of my nails first. Is it true?

Lentiamo.co.uk

Reply: It is. You can only handle contact lenses with your fingertips which is not possible with long nails.

Principle of multifocal contact lenses

Anonymous

Question: Could you please explain to me what the principle of multifocal contact lenses is?

Lentiamo.co.uk

Reply: To put it simply, multifocal contact lenses work on the principle of different pupil dilation when looking at different distances. In the central part of the contact lens, there is a “different prescription” than in the peripheral one. Or they can alternate in concentric circles. The exact method can differ with specific manufacturers.

Another option is correction by “monovision” – using the principle of the “dominant eye”. One eye is focused on distance, the other on near-vision. Contact lenses are commonly used for this method.

Contact lenses with UV filter

Anonymous

Question: Could you please tell me what the difference is when it comes to lenses with a UV filter and without? How does it affect the eye? And one more thing. My current lenses, Soflens 66 (Bausch Lomb) will be discontinued soon. Which ones do you think would be an adequate replacement? Yesterday, I bought a trial pair of Frequency 58 UV. Could you please let me know if it was the right choice or not?

Lentiamo.co.uk

Reply: When it come to the first part of your query – contact lenses with UV filter protect the eye from harmful effects of UV radiation. They don’t protect the conjunctiva or eye lids which are as sensitive to UV radiation as the cornea is. In my opinion, UV filter in contact lenses is not very important because when you need a real protection from the sun, you will also need quality sunglasses that will protect your eye lids and conjunctiva, too. As of the second part of your query – if you are about to change the type of contact lenses, always do it with the help of a contactologist. Don’t buy a new type of lenses without having an eye exam first..

Is it safe to buy contact lenses online?

Anonymous

Question: Is it reliable to buy contact lenses on the internet? Is it possible that they’d be fake and how can I tell if a shop is safe and good?

Lentiamo.co.uk

Reply: Just like in any other industry, it can always happen that some shops will not be reliable. You might thus buy products that were not aimed for your Country's market, that might expire soon or that will be delivered much later than previously advertised. This is why it’s important to choose an e-shop that is reliable and established with a guaranteed service. I think it’s easy to tell if a shop is safe and good, you only have to look around it a bit.

Is it necessary to consult the choice of moisturising eye drops with a contactologist?

Anonymous

Question: If I wanted to buy moisturising eye drops, do I have to talk to an eye doctor first? Is it necessary to buy the same brand as the lenses?

Lentiamo.co.uk

Reply: More than the brand it’s about the problem that the drops should help with. If it’s lubrication of lenses, we can recommend Refresh which is preservative-free.

The difference between Proclear Sphere and Proclear Compatibles contact lenses

Anonymous

Question: I wanted to ask what the difference is between Proclear Sphere and Proclear Compatibles?

Lentiamo.co.uk

Reply: Proclear Compatibles is an older name for the current Proclear Compatibles Sphere CooperVision. It’s merely a name change, the lenses are exactly the same.

What are the - and + symbols?

Maria T.

Question: I wanted to ask what the – and + symbols are? What means what? (I’ve been confused by them). I have prescription distance glasses, 1 dpt on the right eye and ¾ dpt on the left. I also wanted to ask you if you could tell me which contact lenses I could buy.

Lentiamo.co.uk

Reply: The + symbol indicates the convex lens that’s being used for far-sightedness correction (hypermetropia). The – symbol indicates the concave lens that is being used for the correction of short-sightedness (myopia). UnfortunatelyI can’t tell you which contact lenses would work for you as this decision should be made after a proper eye exam. Please see an optometrist or ohptalmologist to have your eyes checked.

What does the eye curvature mean?

Anonymous

Question: An optician’s device measured my curvature as BC 8,7. I wanted to ask what this value means and if I can buy lenses with a 8,6 curvature. And if I did, what are the risks?

Lentiamo.co.uk

Reply: The BC 8.7 value is a lead for choosing the right type of contact lenses. It’s the radius of your cornea curvature which the radius of the contact lens should correspond to. However, it’s not this value alone that’s important, other qualities of the lens also matter, you can’t choose them based only on the curvature. Considering the risks for your eyes all this shouldn’t be taken lightly.

Prescription of glasses and contact lenses

Anonymous

Question: Is it true that if you are short-sighted, you have less dioptres in your contact lenses and if you are far-sighted, you actually have a bit more because the glasses are a bit further away from the eye while contact lens sits directly on it?

Lentiamo.co.uk

Reply: It’s true. If you have 3dtp or more, 0.25 dpt is taken away in case of short-sightedness. If you have more dioptres, the difference can be up to 0.5 dpt. And it’s the other way around with far-sightedness in which case you actually add more dioptres.

Frequency 55 Toric and Frequency XCEL Toric

Anonymous

Question: Could you please explain the difference between Frequency 55 Toric and Frequency XCEL Toric contact lenses? Their price is different but the parameters seem to be the same. I’m not sure what the difference is apart from the material, which is methafilcon A or B. I use Frequency XCEL Toric.

Lentiamo.co.uk

Reply: Frequency 55 Toric are not officially distributed here, which means we are not familiar with their qualities. I can only guess that they will be similar to Frequency 55 Aspheric CooperVision – those lenses are, however, different from Frequency Xcell Toric, when it comes to basic parameters. It is also not possible to simply compare lenses by parameters, it is important to see how a lens fits on a specific eye..

Can I wear contact lenses when I’m ill?

Question: I wanted to ask if I can wear contact lenses when I’m ill (such as down with cold?).

Lentiamo.co.uk

Reply: Definitely don’t use contact lenses during an illness, even if it’s just a cold.

Medical certificate for motor vehicle drivers

Anonymous

Question: I would like to ask for your advice. I have a driving licence (C and D – large vehicles and buses) and I also wear contact lenses with –5 and –7 dpt. When I use them, I have no problems with my eye sight. I would like to know if I could have problems with getting a medical certificate for bus driving in accordance with Act. 277/2004 Coll. regarding fitness to drive. This act includes, among others:

“Disorders, defects or conditions of vision excluding medical fitness to drive are the disorders, defects or conditions of vision which cause such health complications or deviations that are dangerous to road traffic, in particular:

(b) a visual acuity less than 0.8 in the better eye and less than 0.5 in the worse eye; If corrective lenses are needed to attain values of 0.8 and 0.5, the uncorrected acuity of each eye is less than 0.5 or if the minimum acuity (0.5 and 0.8) is achieved either by correction by means of glasses or contact lenses with a power exceeding plus or minus 4 dpt (uncorrected vision = 0.05); the individual suffering from such disorders, defects or conditions does not tolerate the correction well.“

Does this mean that a person with more than 4 dpt is not fit to drive large vehicles or buses? And if yes, can I somehow, with the use of some optical correction or an operation, become fit to drive again? Thank you for your answer.

Lentiamo.co.uk

Reply: The way I understand this paragraph is that according to the law, you have to have your vision corrected to acuity of 0.8 or 0.5 and tolerate it well (see the last sentence of paragraph b), which might not always be the case with corrections over 4 dpt. Which means, if your visual acuity is 0.5/0.8 with –5 and –7 dpt and you tolerate it well, you shouldn’t have a problem.

Frequency of using eye drops

Anonymous

Question: I use Ciba Vision daily contact lenses and Refresh eye drops. I would like to ask, how many times a day can I use the eye drops while wearing lenses? Is there any limit to it so that the lenses don’t lose their quality?

Lentiamo.co.uk

Reply: The need of using moisturising eye drops is determined by the quality and quantity of the tear film and your environment. You will not damage your lenses by using eye drops. If you feel like you use the eye drops too often (more than 3–4× a day), it is possible that they’re not efficient enough. I recommend you browse through the choice we offer for Eye drops to find a suitable solution for your problem.

Can I use solution for moisturising instead of eye drops?

Anonymous

Question: Hello, I would like to ask if I could use a solution for lubricating my eyes when I don’t have eye drops at hand.

Lentiamo.co.uk

Reply: In case of an emergency, you can use a solution to moisturise your eyes (but never a peroxide solution). The effect will be comparatively smaller than with eye drops, though. Peroxide solutions must never be used directly in the eyes, the peroxide element has to be neutralised first.

Period of contact lens use

Anonymous

Question: My question is about taking contact lenses out of the blister – e.g. I would wear them for 3 days and then I’d get ill and wouldn’t be able to wear them. Can I keep them in the case for 2 weeks and then wear them for the remaining 27 days when I get better or do I need to shorten the wearing period by those 14 days?

Lentiamo.co.uk

Reply: This issue is frequently discussed and there’s no clear answer. You need to consider the reasons for interrupting the usage and for how long it happenes. In case you get ill, throw away the pair you’ve been using even if you only wore them once. If you don’t wear the lenses for one day, you can keep the same solution. If it’s for longer, it is necessary to change the solution every day. I wouldn’t recommend interrupting the period of wear for more than 3–4 days. I also wouldn’t do this regularly, it’s better to start using Daily Contact Lenses instead.

Is it necessary to include the fact that you wear contact lenses in your driving license?

Anonymous

Question: I would like to ask if it’s necessary to have some special card for driving saying that I wear contact lenses?

Lentiamo.co.uk

Reply: Yes, if you have the “glasses needed” note in your driving licence, you will have to show a contact lens wearer card to the traffic control. Your contactologist will issue one for you. Newer driving licences that were issued according to EU guidelines have to have the right code.

Change of dioptres

Anonymous

Question: I’ve got a question. I’ve been wearing Air Optix for Astigmatism (-6.00 dpt, cyl. –1.25, acis 110). But it seems to me that my eye sight got worse so I would like to start wearing stronger lenses. My question is:

  1. I would like to order lenses with a slightly stronger prescription –6.25 2) do you think that if I buy lenses with let’s say –6.25 dpt, will I have to change the cylinder and axis as well? I don’t know if I that’s how it works / if the axis and cylinder have any effect on the dioptre.
Lentiamo.co.uk

Reply: Please ask your contactologist (eye doctor) as I can’t answer this question expertly. A professional will make sure you get to wear the correct lenses for your eyes, after giving you trial ones.

Eye check-up

Pavla J.

Question: I would like to ask for advice. I wear contact lenses and will have a regular check-up at my ophthalmologis­t’s soon. I would like to know if I should wear contact lenses or glasses for it? I haven’t found any information about this. Thank you for your advice, Pavla

Lentiamo.co.uk

Reply: I recommend you contact your doctor, at least by phone, and ask them. It is possible that every doctor has different requirements.

Changing diameter and curvature

Anonymous

Question: My curvature is 8,40 and diameter 13,80, do you think that if I order prescription coloured contact lenses (to be used for one day) with curvature 8,60 and diameter 14,00, it will be a problem?

Lentiamo.co.uk

Reply: It is difficult to tell if a different diameter and curvature will suit you. Diameter plays an important role with how the lens fits on the eye – a diameter smaller than the cornea can cause problems and a bigger one can make contact lens application more difficult for users with narrower eye slits. Lens curvature corresponds to the eye curvature and it should copy the cornea as closely as possible. A doctor should measure these parameters for you – if you buy lenses with the wrong curvature, the lens might not sit right on the eye. It could cause gritty feelings, or be too loose. I would definitely recommend you visit a doctor who will measure all parameters, recommend a suitable contact lens type and give you a trial pair. Other parameters such as material, oxygen permeability and water content also matter. So you won't run the risk of buying contact lenses that won’t fit properly.

Can I apply for a code B driving license?

Euka

Question: If I have –5 dioptres on each eye and wear contact lenses, can I apply for code B driving license? I was wondering if there are any legal limitations

Lentiamo.co.uk

Reply: Please ask your eye doctor, who will be able to determine if you are fit to drive or not.

Can I use Ocutein Sensitive eye drops with contact lenses?

Anonymous

Question: I wanted to ask if it’s possible to use Ocutein Sensitive eye drops with contact lenses? Thank you for your answer.

Lentiamo.co.uk

Reply: Unfortunately, we don’t sell Ocutein Sensitive eye drops which means we don’t know if they could be used with contacts or not. I would recommend you ask a pharmacist, or your eye doctor.

Can I combine glasses and lenses?

Petra S.

Question: I wear lenses for distance, –7 dpt. I don’t want my eyes to get used to more dioptres but sometimes I need to have better vision acuity at work. Can I combine lenses and glasses – if I for example bought glasses with –1 dpt for occasional use?

Lentiamo.co.uk

Reply: You should actually consult your eye doctor or a contactologist who will do a check-up and tell you which lenses or glasses you could wear.
